Description

Die Erfindung betrifft ein Kältegerät mit einer an seinem wärmeisolierenden Gehäuse angeschlagenen Tür, an welcher ein drehbar gelagerter, als zweiarmiger Hebel ausgebildeter Türgriff angeordnet ist, welcher einen längeren, als Handgriff zum Öffnen der Tür dienenden Hebelarm und einen kürzeren, beim Betätigen des Handgriffs sich am Gehäuse abstützenden Hebelarm aufweist. Ein solches Gerät ist z.B. aus der DE-U-9 313 978 bekannt.The invention relates to a refrigerator with a struck on its heat-insulating housing Door on which a rotatably mounted, designed as a two-armed lever Door handle is arranged, which is a longer, serving as a handle for opening the door Lever arm and a shorter one, when pressing the handle on the housing has a supporting lever arm. Such a device is e.g. known from DE-U-9 313 978.

Bei Kältegeräten, insbesondere bei mit großflächigen Türen ausgestatteten Gefriergeräten ist man dazu übergegangen, die Türen, um ihr Öffnen zu erleichtern, mit Türöffnungshilfen auszustatten. Diese sind entweder als eine die Magnetdichtung der Türen partiell von dem als ihren Anker dienenden Öffnungsrand des Gehäuses abhebende Mechanik oder als zweiarmiger Hebel ausgebildet, durch dessen längeren, als Handgriff dienenden Hebelarm die zum Öffnen der Tür aufzuwendende Kraft aufgrund seiner Hebellänge deutlich reduziert ist. Die zuletzt genannte Möglichkeit zur Verringerung der Türöffnungskraft ist aus dem deutschen Gebrauchsmuster 18 11 327 bekannt. Hierin ist ein zweiarmiger Hebel gezeigt und beschrieben, welcher drehbar an der Frontseite einer Isoliertüre angeschlagen ist und dessen längerer Hebelarm als Handgriff dient, während der kürzere Hebelarm zum Öffnen der Tür entweder auf ein Abdrückgestänge oder auf einen Abdrückbeschlag einwirkt.For refrigerators, especially freezers with large doors people have started to open the doors to make opening them easier equip. These are either used as a magnetic seal on the doors partially lifting off from the opening edge of the housing serving as its anchor Mechanics or designed as a two-armed lever, through its longer, as a handle serving lever arm the force to open the door due to its lever length is significantly reduced. The latter option to reduce the Door opening force is known from German utility model 18 11 327. Here is a two-armed lever shown and described, which is rotatable on the front of one Insulated door is struck and the longer lever arm serves as a handle while the shorter lever arm to open the door either on a push rod or on a forcing fitting acts.

Der Erfindung liegt die Aufgabe zugrunde, aufbauend auf diesem Stand der Technik, eine Befestigung für einen Türgriff eines Kältegerätes gemäß dem Oberbegriff des Anspruches 1 vorzuschlagen, aufgrund welcher der Türgriff mit einfachen konstruktiven Mitteln an dem von einem dünnwandigen Gehäusemantel und darin eingefüllten Wärmeisolationsmaterial gebildeten Türkorpus weitestgehend biegesteif gehalten ist.The invention is based, based on this prior art, the task Propose attachment for a door handle of a refrigerator according to the preamble of claim 1, due to which the door handle with simple constructive means on the one thin-walled housing jacket and thermal insulation material filled therein Door body is kept largely rigid.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß an der Tür ein Halteelement lösbar festgesetzt ist, welches wenigstens einen sich von der Drehachse des Türgriffs auf die Seite des längeren Hebelarms erstreckenden Führungsabschnitt aufweist, welcher in eine an diesem Hebelarm vorgesehene Gegenführung eingreift und den Türgriff wenigstens annähernd über dem Bereich seines Drehwinkels in Richtung seiner Drehachse formschlüssig abstützt.This object is achieved according to the invention in that a holding element on the door is releasably fixed, which is at least one of the axis of rotation of the door handle on the Side of the longer lever arm extending guide portion, which in a provided on this lever arm engages and the door handle at least approximately over the range of its angle of rotation in the direction of its axis of rotation supported form-fitting.

Durch die erfindungsgemäße Lösung ist für einen an einer wärmeisolierenden Tür eines Kältegerätes anzuordnenden zweiarmigen Türgriff eine Befestigungsmaßnahme geschaffen, welche zielgerichtet die am längeren, als Handgriff dienenden Hebelarm des Türgriffs vor allem bei dessen unbeabsichtigter, unsachgemäßer Betätigung ausgeübten Kräfte an das Halteelement in Form einer Flächenlast auf das Türgehäuse eingeleitet werden. Hierdurch ist eine nahezu punktuelle, gegebenenfalls an der Einleitungsstelle der Kraft hervorgerufene, sowohl die Funktionsfähigkeit beeinträchtigende Deformation des Türgehäuses stets sicher über den gesamten Drehwinkel des Türgriffes, als auch Schaden an diesem, aufgrund punktueller Überbeanspruchung zu vermieden. Darüberhinaus eignet sich eine solche Lösung auch für einen einfachen und zeitsparenden Anschlagwechsel der Tür, da das lösbar festgesetzte Halteelement ohne großen Montageaufwand an der Losseite der Tür zu befestigen ist.The solution according to the invention is for one on a heat-insulating door Refrigeration device to be arranged two-armed door handle created a fastening measure, which is aimed at the longer lever arm of the Door handle especially when it is used unintentionally, improperly Forces applied to the holding element in the form of a surface load on the door housing become. As a result, an almost punctual, possibly at the point of introduction Force induced deformation of the Door housing always safe over the entire rotation angle of the door handle, as well as damage to avoid this due to selective overuse. Furthermore such a solution is also suitable for a simple and time-saving Changing of the door stop, as the releasably fixed holding element is easy to install to be attached to the loose side of the door.

Nach einer bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß das Halteelement an seinem Führungsabschnitt einen sichelartigen Fortsatz aufweist, welcher zur Verlängerung des mit der Gegenführung zusammenwirkenden Führungsabschnitts dient und welcher in eine am Türgriff vorgesehene taschenähnliche Aufnahme einzutauchen vermag, mit welcher er formschlüssig in Richtung der Drehachse des Türgriffes zusammenwirkt.According to a preferred embodiment of the subject matter of the invention, that the holding element has a sickle-like extension on its guide section which cooperates with the counter guide to extend Serves guide section and which in a pocket-like provided on the door handle Can immerse the recording with which it positively in the direction of the axis of rotation of the door handle interacts.

Durch eine derartige Maßnahme ist auf einfache Weise eine noch günstigere Kraftüberleitung der auf den längeren Hebelarm des Türgriffes einwirkenden Betätigungskraft auf das Halteelement erreicht, wodurch die Drehachse des Türgriffes weitestgehend entlastet und damit eine nahezu punktuelle Kraftübertragung über die Drehachse auf das Türgehäuse einerseits und auf den Türgriff andererseits vermieden ist.Such a measure makes it even easier to transfer force even more cheaply the operating force acting on the longer lever arm of the door handle reached the holding element, whereby the axis of rotation of the door handle is largely relieved and thus an almost selective power transmission via the axis of rotation to the Door housing on the one hand and on the door handle on the other hand is avoided.

Besonders sicher und großflächig findet eine Überleitung der am längeren Hebelarm beim Öffnungsvorgang der Tür eingeleiteten Betätigungskraft auf den Türgriff in eine Flächenlast am Türgehäuse und am Türgriff statt, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß am Türgriff neben der Gegenführung an seinem längeren Hebelarm auch an seinem kürzeren Hebelarm eine Gegenführung angeordnet ist, welche zumindest über den Drehwinkel des Türgriffs mit einem weiteren Führungsabschnitt am Halteelement in Richtung der Drehachse des Türgriffs formschlüssig zusammenwirkt.A transfer of the on the longer lever arm is particularly secure and extensive Opening process of the door initiated operating force on the door handle in a Surface load on the door housing and on the door handle instead, if after a next advantageous Embodiment of the object of the invention is provided that next to the door handle the opposite guide on its longer lever arm also on its shorter lever arm a counter guide is arranged, which at least over the angle of rotation of the door handle with a further guide section on the holding element in the direction of the axis of rotation of the Door handle interacts positively.

Fertigungstechnisch besonders kostengünstig, aber dennoch mit einer ausreichenden Führungspräzision herstellbar sind Führungsabschnitte, wenn nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Führungsabschnitte am Halteelement als zwei einander annähernd gegenüberliegende Führungslaschen ausgebildet sind.Technically particularly inexpensive, but still with sufficient Guiding precision can be produced in guiding sections if according to another preferred one Embodiment of the object of the invention is provided that the Guide sections on the holding element as two approximately opposite one another Guide tabs are formed.

Einen besonders großen Einwirkbereich zur Erzeugung einer Flächenlast am Türkorpus und am Türgriff ist durch die Führungslaschen erreicht, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die freien Enden der Führungslaschen am Halteelement voneinander abgewandt sind.A particularly large impact area for generating a surface load on the door body and on the door handle is achieved through the guide tabs if after a next advantageous Embodiment of the subject of the invention is provided that the free Ends of the guide tabs on the holding element are facing away from each other.

Gemäß einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung ist vorgesehen, daß die Führungslaschen am Halteelement durch ein gleichsinniges, stufenförmiges Absetzen der schmäleren Randabschnitte einer flachprofiligen Platte erzeugt sind.According to a next advantageous embodiment of the subject of the invention provided that the guide tabs on the holding element by a co-directional, step-shaped Settling of the narrower edge sections of a flat profile plate generated are.

Der Vorteil einer derartigen Lösung ist darin zu sehen, daß zur Herstellung des Halteelements ein kostengünstiges Halbzeug zur Anwendung kommen kann, bei welchem die Führungstiefe auf einfache Weise durch die Abkröpfung bestimmt ist. Außerdem ermöglicht ein solches Halteelement einen besonders platzsparenden Aufbau. The advantage of such a solution can be seen in the fact that for the production of the holding element an inexpensive semi-finished product can be used, in which the Leadership depth is determined in a simple manner by the offset. Also enables such a holding element has a particularly space-saving construction.
