Description

Die vorliegende Erfindung betrifft einen Türlagerwinkel für die drehbare Aufhängung einer Tür eines schrankartigen Haushaltsgerätes, insbesondere eines Kühlschranks oder Gefrierschranks.The present invention relates to a door bearing bracket for the rotatable suspension of a door of a cabinet-like household appliance, in particular a refrigerator or freezer.

Ein derartiger Türlagerwinkel ist aus dem deutschen Gebrauchsmuster DE 92 06 086 U1 bekannt.Such a door bearing bracket is known from German Utility Model DE 92 06 086 U1.

Herkömmliche Türlagerwinkel dieser Art umfassen einen am Gehäuse des Haushaltsgeräts zu befestigenden Trägerarm, der an einem Ende einen im Wesentlichen vertikal abstehenden Zapfen trägt. Der Zapfen ist vorgesehen, um in eine Bohrung der Tür eingesteckt zu werden und so eine vertikale Schwenkachse für die Tür zu definieren. Im Allgemeinen handelt es sich bei diesem Zapfen um einen massiven Metallstift, der in eine Bohrung des ebenfalls metallischen Trägerarms eingesteckt und in diesem verschweißt oder vernietet ist.Conventional door bearing brackets of this type comprise a support arm to be fastened to the housing of the domestic appliance, which carries a substantially vertically projecting pin at one end. The pin is provided to be inserted into a bore of the door, thus defining a vertical pivot axis for the door. In general, this pin is a solid metal pin, which is inserted into a bore of the likewise metallic support arm and welded or riveted therein.

Die an einem solchen Türlagerwinkel aufgehängte Tür kann ein erhebliches Gewicht erreichen, wenn es sich beispielsweise um eine Kühlschranktür mit Kühlgutabsteller handelt, die im allgemeinen an der Innenseite der Tür befestigt sind, welche mit vergleichsweise gewichtigem Kühlgut wie etwa Getränkeflaschen vollgestellt sind. Die Gehäuse derartiger Kältegeräte neigen mit zunehmendem technischen Fortschritt dazu, immer leichter zu werden, da für die Herstellung der Gehäusewände zunehmend schwere Metallbleche durch leichtgewichtigen Kunststoff ersetzt werden und die Kältemaschinen zunehmend kleiner und damit leichter gebaut werden können. Wenn das Gehäuse eines solchen Kältegeräts nur gering beladen ist, die Tür hingegen voll, so kann diese Entwicklung im Extremfall dazu führen, dass die Standfestigkeit des Gerätes gefährdet ist und das Gerät beim Öffnen der Tür dazu neigt, vornüber zu kippen.The door suspended from such a door bearing bracket can achieve considerable weight, for example, a refrigerator door with a refrigerated goods shelf, which are generally fixed to the inside of the door, which are filled with comparatively heavy refrigerated goods such as beverage bottles. The housing of such refrigerators tend with increasing technical progress to become lighter, since increasingly heavy metal sheets are replaced by lightweight plastic for the production of the housing walls and the chillers are increasingly smaller and thus easier to build. If the housing of such a refrigeration device is only slightly loaded, but the door is full, this development can in extreme cases lead to the endurance of the device being endangered and the device tends to tip over when the door is opened.

Der Erfindung liegt die Aufgabe zugrunde, einen Türlagerwinkel für ein schrankartiges Haushaltsgerät zu schaffen, der diesem eine verbesserte Standfestigkeit verleiht und eine vereinfachte Anbringung des Türlagerzapfens ermöglicht.The invention has for its object to provide a door bearing bracket for a cabinet-like household appliance, which gives this improved stability and allows a simplified attachment of the door journal.

Diese Aufgabe wird durch gelöst durch einen Türlagerwinkel mit den Merkmalen des Anspruchs 1 bzw. des Anspruchs 7.This object is achieved by a door bearing bracket with the features of claim 1 and of claim 7.

Mit diesem Türlagerwinkel ist es möglich, einen Fuß des Kältegeräts in gleicher Weise wie den Lagerzapfen der Tür über die Vorderseite des Gerätegehäuses vorstehend zu platzieren. Diese Maßnahme ist gerade bei demjenigen Vorderfuß des Gerätes besonders wirksam, in dessen Nähe sich die Türaufhängung befindet, da beim Öffnen der Tür der Schwerpunkt des Gesamtgeräts sich nicht nur nach vorn, sondern gleichzeitig auch zu der Seite der Türaufhängung hin verlagert.With this door bearing bracket, it is possible to project a foot of the refrigerator in the same manner as the bearing pin of the door on the front of the device housing. This measure is especially effective for those forefoot of the device, in the vicinity of the door hanger is because when you open the door, the focus of the overall device is not only forward, but also shifted to the side of the door hanger out.

Der erfindungsgemäße Türlagerwinkel kann besonders einfach mit einem höhenverstellbaren Fuß versehen werden, indem der Stiftteil dieses Fußes in einem Hohlraum des Lagerzapfens untergebracht wird. Dieses Merkmal befreit von der Notwendigkeit, einen entsprechenden Hohlraum im Gehäuse des Kältegeräts selbst vorzusehen, wodurch sich die Herstellung des Gehäuses vereinfacht. Die Herstellung des Türlagerwinkels vereinfacht sich auch dadurch, dass der Stiftteil des Fußes zugleich als Träger für den Lagerzapfen dient. Die statische Beanspruchbarkeit des Fußes erlaubt es, die darauf aufgeschobenen Lagerzapfen weniger statisch anspruchsvoll, z.B. aus Kunststoff, auszubilden.The door hinge bracket according to the invention can be particularly easily provided with a height-adjustable foot by the pin part of this foot is housed in a cavity of the journal. This feature frees from the need to provide a corresponding cavity in the housing of the refrigerator itself, thereby simplifying the manufacture of the housing. The production of the door bearing bracket is also simplified in that the pin part of the foot also serves as a carrier for the bearing journal. The static strength of the foot makes it possible for the bearing journals pushed thereon to be less static-demanding, e.g. made of plastic, form.

Die Höhenverstellbarkeit des Fußes wird in einfacher Weise mit Hilfe einer mit dem Lagerzapfen fluchtenden Gewindebohrung des Trägerarms und einem Gewinde des durch diese Gewindebohrung des Trägerarms in den Hohlraum des Lagerzapfens eingreifenden Stiftteils erreicht.The height adjustment of the foot is achieved in a simple manner by means of a bearing pin aligned with the threaded bore of the support arm and a thread of engaging through this threaded bore of the support arm in the cavity of the journal pin part.

Um auch bei einer geringen Länge des Gewindes eine ausreichende Sicherheit des Fußes gegen Verkanten zu erreichen, ist bevorzugt, dass der Hohlraum des Lagerzapfens den Stiftabschnitt im Wesentlichen spielfrei in radialer Richtung aufnimmt. Durch die zumindest im Wesentlichen spielfreie Abstimmung des Stiftteils auf den Hohlraum des Lagerzapfens ist auch eine präzise und spielfreie Lagerung der Tür möglich.In order to achieve a sufficient safety of the foot against tilting even with a small length of the thread, it is preferred that the cavity of the journal receives the pin portion substantially free of play in the radial direction. By at least substantially free of play vote of the pin part on the cavity of the journal and a precise and play-free storage of the door is possible.

Die Gewindebohrung ist vorzugsweise in einem vorspringenden Stutzen des Trägerarms gebildet. Dies ermöglicht die Ausbildung eines Gewindes von für eine hohe Tragkraft des Fußes ausreichender Länge, auch wenn das Material des Trägerarms eine dieser Länge entsprechende Dicke nicht aufweist. Vorzugsweise ist der vorspringende Stutzen einteilig aus dem Material des Trägerarms geformt, z.B. in Art eines Gewindedurchzuges ausgebildet.The threaded bore is preferably formed in a projecting neck of the support arm. This allows the formation of a thread of sufficient length for a high load capacity of the foot, even if the material of the support arm does not have a thickness corresponding to this length. Preferably, the protruding neck is integrally molded from the material of the support arm, e.g. formed in the manner of a thread passage.

Erfindungsgemäß ist ferner bevorzugt, dass der Lagerzapfen, egal ob hohl und zum Aufnehmen des Stiftteiles eines Fußes ausgelegt oder nicht, mit dem Trägerarm über einen auf einen Endabschnitt des Trägerarms aufschiebbaren und an diesem verrastbaren Steckschuh verbunden ist. Dieser Steckschuh, der vorzugweise aus einem festen Kunststoffmaterial besteht, erlaubt gleichzeitig eine optisch ansprechende Verkleidung des Endabschnitts des Trägerarms, so dass auf eine aufwendige Oberflächenbearbeitung, Lackierung oder dergleichen des Trägerarms verzichtet werden kann. Wenn der Trägerarm mit dem oben erwähnten Stutzen versehen ist, kann dieser in zweckmäßiger Weise auch als Rastpunkt für eine Zunge des Steckschuhs dienen.According to the invention it is further preferred that the bearing pin, whether hollow and designed for receiving the pin part of a foot or not, is connected to the support arm via a push-on an end portion of the support arm and latchable thereto at this plug shoe. This plug-in shoe, which is preferably made of a solid plastic material, at the same time allows a visually appealing panel of the end portion of the support arm, so that can be dispensed with a complex surface treatment, painting or the like of the support arm. If the support arm is provided with the above-mentioned neck, this can also serve as a locking point for a tongue of the boot in an appropriate manner.

Der Steckschuh und der Lagerzapfen sind vorzugsweise einteilig aus Kunststoff gebildet.The plug-in shoe and the bearing journal are preferably formed in one piece from plastic.

Die Erfindung betrifft ebenfalls ein Haushaltsgerät, das wenigstens einen Türlagerwinkel wie oben definiert aufweist.The invention also relates to a domestic appliance having at least one door bearing bracket as defined above.

Der Trägerarm 1 hat einen in etwa U-förmigen Querschnitt, wodurch dem Trägerarm 1 durch die zwei U-Profil-Schenkel 19 eine hohe Biegesteifigkeit verliehen ist.The support arm 1 has an approximately U-shaped cross-section, whereby the support arm 1 is given a high bending stiffness by the two U-profile legs 19.

Ein dem Steckschuh 2 gegenüberliegender Endabschnitt des Trägerarms 1 ist zu einer kurzen schmalen Zunge 6 geformt, die durch eine eingeprägte Vertiefung 8 ebenfalls hohe Biegesteifigkeit aufweist. Die Zunge 6 ist vorgesehen zum formschlüssigen Einschieben in eine Öse 20 eines Kältegerätegehäuses.A plug-in shoe 2 opposite end portion of the support arm 1 is formed into a short narrow tongue 6, which also has high flexural rigidity by an impressed recess 8. The tongue 6 is provided for the positive insertion into an eyelet 20 of a refrigeration device housing.

Fig. 2 ist eine perspektivische Ansicht des unteren Bereichs eines Kältegerätegehäuses, die die Anbringung des Türlagerwinkels an dem Gehäuse veranschaulicht. Eine ungefähr mittig am Trägerarm 1 gebildete Bohrung 7 ist vorgesehen, um eine Schraube aufzunehmen, mit der der Trägerarm 1 von unten an dem Gehäuse festgeschraubt wird. Für die feste Montage des Trägerarms genügt es also, zunächst dessen Zunge 6 in die Öse des Gehäuses einzustecken und ihn dann durch die Bohrung 7 festzuschrauben.Fig. 2 is a perspective view of the lower portion of a refrigerator housing illustrating the attachment of the door bearing bracket to the housing. An approximately centrally formed on the support arm 1 bore 7 is provided to receive a screw with which the support arm 1 is screwed from below to the housing. For the fixed mounting of the support arm so it is sufficient to first insert the tongue 6 in the eye of the housing and then screw it through the hole 7.

Der Lagerzapfen 3 greift in die bereits erwähnte Lagerbohrung an der schrägen Unterseite einer Tür 21 ein; das abgeflacht ausgebildete Ende des Lagerzapfens 3 trägt das Gewicht der Tür 21.The bearing pin 3 engages in the already mentioned bearing bore on the oblique underside of a door 21; the flattened trained end of the journal 3 carries the weight of the door 21st

Fig. 3 ist eine Ansicht des Türlagerwinkels in der gleichen Perspektive wie Fig. 1, bei der allerdings der Steckschuh 2 und der mit ihm verbundene Lagerzapfen 3 weggelassen sind, um den Fuß 4 vollständiger zeigen zu können. Ein vom Basisabschnitt 5 vertikal nach oben abstehender Stiftabschnitt 9 ist mit einem Außengewinde versehen, das mit einem Innengewinde einer Bohrung 10 des Trägerarms 1 in Eingriff ist und über das das Gewicht des Kühlschranks auf den Fuß 4 übertragen wird. Durch Drehen des Fußes 4 ist die Höhe des Trägerarms 1 über einer Standfläche einstellbar.Fig. 3 is a view of the door bearing bracket in the same perspective as Fig. 1, in which, however, the plug shoe 2 and the associated bearing pin 3 are omitted in order to show the foot 4 more fully. A pin portion 9 protruding vertically upward from the base portion 5 is provided with an external thread which engages an internal thread of a bore 10 of the support arm 1 and via which the weight of the refrigerator is transmitted to the foot 4. By turning the foot 4, the height of the support arm 1 is adjustable over a standing surface.

Fig. 4 ist wiederum eine perspektivische Ansicht des Türlagerwinkels in der gleichen Perspektive wie Figs. 1 und 2, bei der allerdings der Steckschuh 2 und der Lagerzapfen 3 in Längsrichtung des Trägerarms 1 aufgeschnitten dargestellt sind. In dieser Darstellung erkennt man, dass der mit dem Steckschuh 2 einteilig ausgeformte Lagerzapfen 3 einen nach unten offenen Hohlraum 12 aufweist, in den der Stiftabschnitt 9 eingreift. Der Außendurchmesser des Stiftabschnitts 9 entspricht mit geringer Toleranz dem Innendurchmesser des Hohlraums 12. Der Lagerzapfen 3 verhindert so ein ungewolltes Verkanten des Stiftabschnitts 9 und schützt so das Gewinde des Stiftabschnitts 9 und der Bohrung 10 vor Beschädigung. Die im Wesentlichen spielfreie Aufbringung des Lagerzapfens 3 auf den Stiftabschnitt 9 schafft zugleich auch die Voraussetzung für eine spielfreie Lagerung der Tür 21 am Lagerzapfen 3.4 is again a perspective view of the door bearing bracket in the same perspective as FIGS. 1 and 2, in which, however, the plug-in shoe 2 and the bearing pin 3 are shown cut in the longitudinal direction of the support arm 1. In this illustration, it can be seen that the bearing pin 3 integrally formed with the plug-in shoe 2 has a downwardly open cavity 12 in which the pin portion 9 engages. The outer diameter of the pin portion 9 corresponds with a small tolerance to the inner diameter of the cavity 12. The journal 3 thus prevents accidental tilting of the pin portion 9 and thus protects the thread of the pin portion 9 and the bore 10 from damage. The essentially play-free application of the bearing pin 3 on the pin portion 9 at the same time also creates the prerequisite for a play-free mounting of the door 21 on the bearing journal. 3

Fig. 5 zeigt eine perspektivische Ansicht des Türlagerwinkels von unten, wobei der Fuß 4 weggelassen ist. Man erkennt, dass die Bohrung 10 des Trägerarms 1 an dessen Unterseite durch einen Stutzen 13 verlängert ist, der durch Aufdornen einer ursprünglich kleineren Bohrung aus dem Material des Trägerarms 1 geformt ist. Dieser Stutzen 13 hat eine zweifache Funktion. Zum einen erlaubt er, das Innengewinde der Bohrung 7 wesentlich länger zu machen, als es der eigentlichen Materialstärke des Trägerarms 1 entspricht, so dass der Fuß 4 ohne Gefahr einer Beschädigung des Gewindes mit hohem Gewicht belastet werden kann, zum anderen dient er als Rastanschlag für eine flexible Zunge 14 des Steckschuhs 2 und hält diesen so am Trägerarm 1 fixiert, auch wenn der Stiftabschnitt 9 des Fußes nicht in seinen Hohlraum eingreift. Ausgangspunkt der Zunge 14 ist eine Brücke 15, die zwei Seitenflanken des Steckschuhs 2 unterhalb des Trägerarms 1 miteinander verbindet und so die Steifigkeit des Steckschuhs und seine Belastbarkeit durch auf den Lagerzapfen 3 einwirkende Kippmomente erhöht.Fig. 5 shows a perspective view of the door bearing bracket from below, with the foot 4 is omitted. It can be seen that the bore 10 of the support arm 1 is extended at its bottom by a nozzle 13 which is formed by thinning an originally smaller bore of the material of the support arm 1. This nozzle 13 has a dual function. On the one hand, it allows to make the internal thread of the bore 7 much longer than it corresponds to the actual material thickness of the support arm 1, so that the foot 4 can be loaded without risk of damaging the thread with high weight, on the other hand it serves as a stop for a flexible tongue 14 of the plug shoe 2 and keeps it fixed on the support arm 1, even if the pin portion 9 of the foot does not engage in its cavity. Starting point of the tongue 14 is a bridge 15 which connects two side edges of the plug shoe 2 below the support arm 1 with each other and thus increases the rigidity of the plug shoe and its load capacity by acting on the bearing pin 3 tilting moments.

Wie man an Fig. 6 erkennt, ist der Gedanke, den Lagerzapfen mit Hilfe eines Steckschuhs am Trägerarm zu befestigen, auch auf den oberen Türlagerwinkel einer Kältegerätetür übertragbar. Man erkennt hier, in auseinander gezogener Darstellung, einen Trägerarm 1' mit einer Steckzunge 16 und einem von der Steckzunge 16 abgewinkelten Basisabschnitt 17, in dem mehrere Bohrungen zum Verschrauben an einem Kältegerätegehäuses gebildet sind. Der Steckschuh 2' hat eine geschlossene Ober- und Unterseite; von der Unterseite steht der massive Lagerzapfen 3' ab. Rasthaken 18 an den Seitenwänden des Steckschuhs 2' sind vorgesehen, um in seitliche Einkerbungen 19 der Steckzunge 16 einzugreifen und den Steckschuh so zu verankern.As can be seen from FIG. 6, the idea of securing the bearing journal to the carrier arm with the aid of a plug-in shoe can also be applied to the upper door bearing bracket of a refrigerator door. It can be seen here, in exploded view, a support arm 1 'with a tongue 16 and a bent from the tongue 16 base portion 17 in which a plurality of holes are formed for screwing to a refrigerator housing. The plug shoe 2 'has a closed top and bottom; from the bottom of the massive bearing pin 3 'from. Latch hooks 18 on the side walls of the plug shoe 2 'are provided to engage in lateral notches 19 of the tongue 16 and to anchor the boot so.
