Die Erfindung betrifft eine Lagerung für eine verschwenkbare Tür eines Haushaltsgerätes, wie einem Kältegerät, einen Wäschetrockner oder dergleichen mit von einem Befestigungsteil getragenen Lagerelement und einer zu dessen drehbaren Lagerung vorgesehenen Lageraufnahme.The invention relates to a mounting for a pivotable door of a household appliance, such as a refrigerator, a tumble dryer or the like, with a bearing element carried by a fastening part and a bearing receptacle provided for its rotatable mounting.
Bei Kältegeräten ist es Stand der Technik, die zur Lagerung ihrer Türen zum Einsatz kommenden Türlagerwinkel aus mehreren, separat gefertigten Einzelteilen aufzubauen. Diese Einzelteile, welche neben einem ein- oder zweiteilig aufgebauten winkelförmigem Befestigungsprofil noch einen Türlagerbolzen umfassen, sind miteinander durch eine Nietverbindung verbunden, wobei zur Befestigung des Türlagerbolzens am Lagerbolzenträger auch Schraubverbindungen zum Einsatz kommen. Derartig konzipierte Türlagerwinkel ziehen neben einer aufwendigen Logistik, um alle Einzelteile zur Fertigung des Türlagerwinkels termingerecht am Fertigungsort bereitstellen zu können, noch eine aufwendige Fertigung nach sich, welche neben den Fügetechniken für die einzelnen Elemente auch noch die Befestigungstechniken umfassen muß.For refrigeration appliances, it is state of the art to build the door bracket used for storing your doors from several separately manufactured individual parts. These individual parts, which in addition to a one-part or two-part angled fastening profile also comprise a door bearing bolt, are connected to one another by a rivet connection, screw connections also being used for fastening the door bearing bolt to the bearing bolt carrier. In addition to complex logistics, in order to be able to provide all individual parts for the production of the door bearing angle on time at the production site, door bearing angles designed in this way also involve complex production, which in addition to the joining techniques for the individual elements must also include the fastening techniques.
Der Erfindung liegt die Aufgabe zugrunde, eine Lagerung gemäß dem Oberbegriff des Anspruches 1 mit einfachen konstruktiven Maßnahmen zu verbessern.The invention has for its object to improve a storage according to the preamble of claim 1 with simple design measures.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das Lagerelement mit einem lagernd in die Lageraufnahme einzugreifen vermögenden Zwischenstück ver- sehen und einstückig zusammen mit dem Befestigungsteil aus einem flachprofiligen Werkstoff gebildet ist.This object is achieved according to the invention in that the bearing element is provided with an intermediate piece capable of engaging the bearing receptacle. see and is integrally formed together with the fastener from a flat profile material.
Durch die erfindungsgemäße Lösung ist ein Türlagerwinkel bereitgestellt, für dessen Herstellung wegen seines im wesentlichen einstückigen Aufbaus sich eine aufwendige Füge- und Fertigungstechnologie in Form eines entsprechenden Herstellungsautomaten erübrigt. Durch seinen einstückigen Aufbau ist der erfindungsgemäße Türlagerwinkel mit wesentlich geringeren Fertigungstoleranzen belastet, wodurch sich die Montage des Türlagerwinkels am Gehäuse eines Haushaltgerätes, wie einem Kältegerät oder dergleichen deutlich vereinfacht. Durch die Herstellung des Türlagerwinkels aus flachprofiligem Werkstoff können für die Herstellung kostengünstige Halbzeuge Anwendung finden. Unter flachprofiligem Werkstoff sollen hier Werkstoffe mit rechteckförmigen, ovalen, elliptischen Querschnitten oder dergleichen verstanden sein. Ferner bietet die erfindungsgemäße Lösung die Möglichkeit, das Zwischenstück hinsichtlich seiner Werkstoffeigenschaften an unterschiedliche Lagerbelastungen anzupassen.The solution according to the invention provides a door bearing bracket, for the manufacture of which, because of its essentially one-piece construction, a complex joining and manufacturing technology in the form of a corresponding manufacturing machine is unnecessary. Due to its one-piece construction, the door bearing bracket according to the invention is loaded with significantly lower manufacturing tolerances, which significantly simplifies the assembly of the door bearing bracket on the housing of a household appliance, such as a refrigerator or the like. By manufacturing the door bracket from flat profile material, inexpensive semi-finished products can be used for the production. Flat-profile material is to be understood here as meaning materials with rectangular, oval, elliptical cross sections or the like. Furthermore, the solution according to the invention offers the possibility of adapting the intermediate piece to different bearing loads with regard to its material properties.
Nach einer bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß das Zwischenstück als einseitig geschlossener, zylindrisch ausgeführter Hohlzapfen ausgebildet ist, in dessen Hohlraum das Lagerteil einzugreifen vermag.According to a preferred embodiment of the object of the invention it is provided that the intermediate piece is designed as a cylindrically shaped hollow pin closed on one side, in the cavity of which the bearing part is able to engage.
Ein derartiges Zwischenstück ist einerseits in sich besonders formsteif und andererseits besonders gut für Lagerführungen im Zusammenwirken mit einer z.B. in der Tür eines Kältegerätes vorgesehenen Lageraufnahme geeignet.Such an intermediate piece is on the one hand particularly dimensionally stable and on the other hand particularly good for bearing guides in cooperation with a e.g. suitable storage in the door of a refrigerator.
Besonders einfach und langzeitpositionsgenau gehaltert ist das Zwischenstück am Lagerelement, wenn nach einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß das Zwischenstück form- und/oder kraftschlüssig mit dem Lagerelement verbindbar ist. Ferner sind den Verschleiß des Zwischenstücks fördernde Drehbewegungen zwischen ihm und dem Lagerelement vermieden. Nach einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß das als Hohlzapfen ausgebildete Zwischenstück mit seiner Zapfeninnenseite form- und/oder kraftschlüssig mit dem Lagerelement zusammenwirkt.The intermediate piece on the bearing element is held particularly simply and in the long-term position if, according to a next preferred embodiment of the object of the invention, it is provided that the intermediate piece can be connected to the bearing element in a positive and / or non-positive manner. Furthermore, rotary movements promoting the wear of the intermediate piece between it and the bearing element are avoided. According to a next preferred embodiment of the object of the invention, it is provided that the intermediate piece, which is designed as a hollow pin, interacts with the bearing element with its inside of the pin in a positive and / or non-positive manner.
Eine derartige Verbindung zwischen dem Lagerelement und dem Zwischenstück ist einerseits besonders unauffällig und andererseits besonders sicher vor unbeabsichtigter Beschädigung. Darüber hinaus ist eine derartige Befestigungsmaßnahme des Zwischenstücks am Lagerelement besonders montagefreundlichSuch a connection between the bearing element and the intermediate piece is on the one hand particularly inconspicuous and on the other hand particularly safe from accidental damage. In addition, such a fastening measure of the intermediate piece on the bearing element is particularly easy to assemble
Besonders einfach ist die formschiüssige Verbindung zwischen dem Zwischenstück und dem Lagerelement ausgebildet, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die Zapfeninnenseite des Hohlzapfens mit wenigstens zwei einander gegenüberliegenden Aufnahmenuten ausgestattet ist, in welche die schmäleren Seiten des flachprofiligen Lagerelements formschlüssig einzugreifen vermögen.The positive connection between the intermediate piece and the bearing element is particularly simple if, according to a next advantageous embodiment of the object of the invention, it is provided that the inside of the pin of the hollow pin is equipped with at least two mutually opposite receiving grooves into which the narrower sides of the flat-profile bearing element have a positive fit are able to intervene.
Besonders positionsgenau ist die Eindringtiefe des Zwischenstücks in die Lageraufnahme bestimmt, wenn nach einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß das als Hohlzapfen ausgebildete Zwischenstück an seiner offenen Zapfenseite mit einem Bund versehen ist, welcher als Anschlag für die Lageraufnahme dient.The depth of penetration of the intermediate piece into the bearing receptacle is determined particularly precisely if, according to a next preferred embodiment of the object of the invention, it is provided that the intermediate piece designed as a hollow pin is provided on its open pin side with a collar which serves as a stop for the bearing receiving piece.
Entsprechend einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß der flachprofilige Werkstoff plastisch verformbar ausgebildet ist und daß das Lagerelement am freien Ende einer Abwinklung des Befestigungsteiles angeordnet ist.According to a further preferred embodiment of the object of the invention, it is provided that the flat-profile material is designed to be plastically deformable and that the bearing element is arranged at the free end of an angled portion of the fastening part.
Durch eine derartige Lösung ist der Drehpunkt der Tür auf besonders einfache Weise entsprechend dem Tür- und Geräteaufbau anpaßbar. Darüber hinaus eröffnet die Verwendung eines plastisch verformbaren Werkstoffes eine besonders kostengünstige Herstellung verschiedener, an unterschiedliche Gerätetypen gesondert angepaßte Türlagerwinkel. Nach einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Abwinklung zur Längsachse des Befestigungsteiles unter einem von 90° verschiedenen Zwischenwinkel zur Längsachse des Befestigungsteiles angeordnet und an seinem freien Ende das entsprechend dem Zwischenwinkel abgewinkelte Lagerelement vorgesehen ist.With such a solution, the pivot point of the door can be adapted in a particularly simple manner in accordance with the door and device structure. In addition, the use of a plastically deformable material opens up a particularly cost-effective production of various door bearing angles that are specially adapted to different device types. According to a next preferred embodiment of the object of the invention it is provided that the bend to the longitudinal axis of the fastening part is arranged at an intermediate angle which is different from 90 ° to the longitudinal axis of the fastening part and that the bearing element which is angled according to the intermediate angle is provided at its free end.
Durch die schräg zur Längsachse des Befestigungsteiles angeordnete Abwinklung ergibt sich eine Querschnittsvergrößerung für die Abwinklung, so daß deren Widerstandsmoment gegen Verdrehung und somit deren Steifigkeit deutlich erhöht ist. Zudem ist durch die schräge Anordnung der Abwinklung der Längsachse des Befestigungsteiles auf einfache Weise ein unterschiedliches Höhenniveau für das Lagerelement bezüglich des Befestigungsteiles, entsprechend den Höhenabmessungen der zu lagernden Tür und den Lagererfordernissen, erreichbar.The angled arrangement at an angle to the longitudinal axis of the fastening part results in an increase in cross section for the angled portion, so that its moment of resistance to torsion and thus its rigidity is significantly increased. In addition, the oblique arrangement of the bend of the longitudinal axis of the fastening part makes it easy to achieve a different height level for the bearing element with respect to the fastening part, corresponding to the height dimensions of the door to be stored and the storage requirements.
Besonders sicher abgestützt ist das Zwischenstück, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß an der Abwinklung eine Auflagefläche vorgesehen ist, auf welcher das Zwischenstück aufzuliegen vermag.The intermediate piece is particularly securely supported if, according to a next advantageous embodiment of the object of the invention, it is provided that a support surface is provided on the bend, on which the intermediate piece can lie.
Fertigungstechnisch besonders einfach und kostengünstig herstellbar ist die Auflagefläche für das Zwischenstück, wenn nach einer letzten bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Auflagefläche an einen im wesentlichen senkrecht zum Lagerelement angeordneten Umbug vorgesehen ist.The support surface for the intermediate piece is particularly simple and inexpensive to manufacture if, according to a last preferred embodiment of the object of the invention, it is provided that the support surface is provided on a fold arranged essentially perpendicular to the bearing element.

Gemäß Fig. 1 ist eine als Standgerät ausgeführte Kühl-/Gefrierkombination 10 gezeigt, deren wärmeisolierten Gehäuse 11 ein Normalkühlfach 12 mit Kühlgutablagen 13 und ein unterhalb dem Normalkühlfach 12 wärmeisolierend davon getrennt, ein Gefrierfach 14 mit schubladenartigen Gefriergutbehältern 15 angeordnet ist. Sowohl das Normalkühlfach 12 als auch das Gefrierfach 14 ist mit je einer Tür 16 bzw. 17 verschließbar, welche über am Gehäuse 11 festgesetzte Türlagerwinkel 20 verschwenkbar am Gehäuse 11 gelagert sind.1, a refrigerator / freezer combination 10 designed as a standing device is shown, the heat-insulated housing 11 of which has a normal refrigerated compartment 12 with refrigerated goods racks 13 and a thermally insulated underneath it, a freezer compartment 14 with drawer-like frozen goods containers 15. Both the normal refrigerator compartment 12 and the freezer compartment 14 can each be closed with a door 16 or 17, which are pivotably mounted on the housing 11 via door bearing brackets 20 fixed to the housing 11.
Wie insbesondere Fig. 2 zeigt, weist der aus flachprofiligem, beispielsweise aus Flachstahl gemäß den DIN1017 spanlos durch Abwinklung geformte Türlagerwinkel 20 einen Befestigungsteil 21 auf, mit welchem er am Gehäuse 11 festgesetzt ist. Der Befestigungsteil 21 ist zum Zwecke seiner Festsetzung am Gehäuse 11 mit voneinander beabstandeten Durchgangsbohrungen 22 versehen, welche im Befestigungszustand von nichtgezeigten Befestigungschrauben durchdrungen sind. An den Befestigungsteil 21 schließt sich eine Abwinklung 23 an, deren Abwinklungsachse 24 (in Fig. 3 durch gestrichelte Linien dargestellt) unter einem von 90° verschiedenen Zwischenwinkel α zur Längsachse des Befestigungsteiles 21 angeordnet ist. Durch eine Variation des Zwischenwinkels α ist die Möglichkeit geschaffen, verschiedene Türkonstruktionen, wie dies beispielsweise bei Türen, angelenkt mit einem Flachscharnier oder bei sogenannten Schlepptüren der Fall sein kann, mit ein und derselben Befestigungsposition am Gehäuse 11 lagern zu können. Der Türlagerwinkel 20 weist nahe dem freien Ende seiner Abwinklung 23 einen mit seinem freien Ende vom Befestigungsteil 21 weggerichteten Umbug 25 auf, dessen von der Abwicklung 23 weggerichtete Außenseite als Auflagefläche 26 dient.

Auf das Lagerelement 30 ist ein beispielsweise aus Kunststoffspritzguß gefertigtes Zwischenstück 32 aufbringbar. Dieses weist weitestgehend die Form eines mit zylindrischem Querschnitt ausgestatteten Hohlzapfens auf, dessen den Hohlraum umgebende Zapfenwandung einen in einer nicht dargestellten Lageraufnahme an den Türen 16 bzw. 17 zu deren drehbaren Lagerung einbringbaren Lagerbolzen 33 bildet, welcher um Zugang zu dem Hohlzapfeninnenraum zu haben, einseitig mit einer Öffnung 34 ausgestattet ist. Der als Hohlzapfen ausgebildete Lagerbolzen 33 ist an seiner dem Hohlraum zugewandten Wandungsinnenseite mit vier um je 90° versetzte, paarweise einander gegenüberliegend angeordnete Aufnahmenuten 35 versehen, welche in die Bolzenwandung eingeformt und mit ihrer offenen Nutenseite einander zugewandt sind. In je ein Paar der Aufnahmenuten 35 sind die mit den Seitenflächen 31 versehenen seitlichen Ränder des Lagerelementes 30 formschlüssig einbringbar, wodurch das Zwischenstück 32 verdrehsicher um seine Längsachse am Lagerelement 30 gehalten ist. Das Zwischenstück 32 ist an seiner offenen Hohlzapfenseite mit einem in Form eines Ovals ausgebildeten, asymmetrisch zum Zentrum des Lagerbolzens angeordneten Anschlagbund 36 versehen, dessen der Öffnungsseite des Hohlraumes zugewandte Außenseite als Anschlagfläche 37 dient und durch ihr Aufliegen auf der Auflagefläche 26 die Einstecktiefe des Lagerelementes 30 in die Aufnahmenuten 35 bestimmt. Gegenüber der Anschlagfläche 37 ist der Anschlagbund 36 mit einer Auflagefläche 38 ausgestattet, an welcher sich vor allem die nicht dargestellten, tieferliegenden Lageraufnahmen an den Türen 16 und 17 in deren Montagezustand am Gehäuse 11 anhand der paarweise zur Lagerung der Türen 16 und 17 vorgesehenen Türlagerwinkel 20 abstützen. As shown in FIG. 2 in particular, the door bearing bracket 20 made of flat profile, for example of flat steel according to DIN1017 without cutting by bending, has a fastening part 21 with which it is fixed to the housing 11. The fastening part 21 is provided for the purpose of fixing it on the housing 11 with spaced through bores 22 which are penetrated by fastening screws, not shown, in the fastening state. The fastening part 21 is followed by a bend 23, the bend axis 24 (shown in FIG. 3 by dashed lines) at an intermediate angle α, which is different from 90 °, to the longitudinal axis of the fastening part 21. A variation of the intermediate angle α creates the possibility of being able to store different door constructions, such as, for example, in the case of doors hinged with a flat hinge or in the case of so-called trailing doors, with one and the same fastening position on the housing 11. Near the free end of its bend 23, the door bearing bracket 20 has a fold 25 which is directed away from the fastening part 21 with its free end, the outside of which is directed away from the development 23 and serves as a support surface 26. The fold 25 is produced by angling a plate-like projection along the bending axis 27, the outside of the fold serving as the support surface 26 lying in a plane parallel to one of the outer edges of the fastening part 21. Adjacent to fold 25 a further bend 28 is provided at the free end of the bend 23, the bend axis 29 of which runs parallel to the bend axis 24 (see FIG. 3) and the larger outer surfaces of which run parallel to the larger outer surfaces of the fastening part 21 provided with the through bores 22. The bend 28 carries a journal-like bearing element 30, the free end of which protrudes from the bearing surface 26 and the narrower side surfaces 31 serve as guides. An intermediate piece 32, for example made of plastic injection molding, can be applied to the bearing element 30. This has largely the shape of a hollow pin equipped with a cylindrical cross-section, the pin wall surrounding the cavity forming a bearing pin 33 which can be inserted in a bearing receptacle (not shown) on the doors 16 or 17 for its rotatable mounting and which has access to the hollow pin interior on one side is equipped with an opening 34. The bearing pin 33, which is designed as a hollow pin, is provided on its inner wall side facing the cavity with four receiving grooves 35 which are offset by 90 ° and are arranged opposite one another in pairs and which are formed in the pin wall and face one another with their open groove side. The side edges 31 of the bearing element 30, which are provided with the side surfaces 31, can be positively inserted into a pair of the receiving grooves 35, as a result of which the intermediate piece 32 is held on the bearing element 30 such that it cannot rotate about its longitudinal axis. The intermediate piece 32 is provided on its open hollow pin side with a stop collar 36 designed in the form of an oval and arranged asymmetrically with respect to the center of the bearing bolt, the outside of which faces the opening side of the cavity serves as a stop surface 37 and, by resting on the contact surface 26, the insertion depth of the bearing element 30 determined in the receiving grooves 35. Compared to the stop surface 37, the stop collar 36 is equipped with a support surface 38, on which, above all, the lower bearing receptacles (not shown) on the doors 16 and 17 in their assembled state on the housing 11 are based on the door bearing bracket 20 provided in pairs for mounting the doors 16 and 17 support.
