Description

Die Erfindung betrifft eine Türverriegelung zur Verriegelung von Kühlschränken nach dem Oberbegriff des Schutzanspruchs 1.The invention relates to a door lock for locking refrigerators according to the preamble of claim 1.

Insbesondere bei Klein-Kühlschränken, die in Fahrzeuge wie Wohnmobile, Boote etc. eingebaut sind, ist nach dem Stand der Technik eine Türverriegelung vorgesehen, welche den üblichen magnetischen Türverschluß ergänzt. Eine derartige ergänzende Verriegelung ist insbesondere deshalb notwendig, um zu verhindern, daß das im Kühlschrank gelagerte Kühlgut bei Unfällen nicht aus dem Kühlschrank geschleudert wird.In the case of small refrigerators in particular, which are installed in vehicles such as mobile homes, boats, etc., a door lock is provided according to the prior art which supplements the customary magnetic door lock. Such a supplementary lock is particularly necessary to prevent the refrigerated goods stored in the refrigerator from being thrown out of the refrigerator in the event of an accident.

Bislang ist nach dem Stand der Technik eine Türverriegelung für Kühlschranktüren bekannt, die einen am Kühlschrankgehäuse angebrachten, in Richtung der Kühlschranktür verschiebbaren Verriegelungsstift umfaßt, der in Verriegelungsposition in eine in der Kühlschranktür vorgesehene Bohrung eingreift und somit die Kühlschranktür gegenüber dem Kühlschrankgehäuse fixiert.To date, a door lock for refrigerator doors is known according to the prior art, which comprises a locking pin which is attached to the refrigerator housing and can be displaced in the direction of the refrigerator door, which engages in the locking position in a bore provided in the refrigerator door and thus fixes the refrigerator door relative to the refrigerator housing.

Es hat sich bei Crash-Tests jedoch herausgestellt, daß diese Einpunktverriegelung nach dem Stand der Technik unzureichend ist. Insbesondere bei extremen Belastungen, wie bei Unfällen, kann die Kühlschranktüre durch im Kühlschrank aufgenommenes Kühlgut derart deformiert werden, daß die Türe aus der Verriegelungsposition ausweicht und geöffnet wird.However, it has been found in crash tests that this single-point locking system according to the prior art is insufficient. Particularly in the case of extreme loads, such as in the event of accidents, the refrigerator door can be deformed by items to be refrigerated in such a way that the door escapes from the locking position and is opened.

Aufgabe der Erfindung ist es den oben beschriebenen Nachteil zu beheben und hierfür eine einfache und kostengünstig herstellbare Vorrichtung anzugeben.The object of the invention is to eliminate the disadvantage described above and to provide a simple and inexpensive device for this purpose.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Schutzanspruchs 1 gelöst, wobei sich zweckmäßige Weiterbildungen der Erfindung aus den in den Unteransprüchen beschriebenen Merkmalen ergeben.This object is achieved by the characterizing features of claim 1, expedient developments of the invention resulting from the features described in the subclaims.

Nach Maßgabe der Erfindung wird die gestellte Aufgabe dadurch gelöst, daß durch Stellen des Verriegelungsstiftes in eine Verriegelungsposition eine Verriegelungseinrichtung betätigt wird, so daß die Kühlschranktür an einem zweiten Verriegelungspunkt verriegelbar ist.According to the invention, the object is achieved in that a locking device is actuated by placing the locking pin in a locking position, so that the refrigerator door can be locked at a second locking point.

Vorteilhafterweise umfaßt die Verriegelungseinrichtung eine verschiebbar in Führungen innerhalb der Kühlschranktür aufgenommene Stange, die durch Betätigung des Verriegelungsstiftes nach unten gedrückt wird. Das über die Unterkante der Kühlschranktür herausragende Ende der Stange greift dabei gleichzeitig in eine Bohrung ein, die an einem zweiten, fest mit dem Kühlschrankgehäuse verbundenen Vorsprung vorgesehen ist. Bei Rückstellen des Verriegelungsstiftes in eine entriegelte Position wird die Stange durch elastische Mittel ebenfalls in eine entriegelte Position zurückgestellt.Advantageously, the locking device comprises a rod which is slidably received in guides within the refrigerator door and which is pressed down by actuation of the locking pin. The end of the rod protruding over the lower edge of the refrigerator door simultaneously engages in a bore which is provided on a second projection which is fixedly connected to the refrigerator housing. When the locking pin is returned to an unlocked position, the rod is also returned to an unlocked position by elastic means.

Die beschriebene relativ einfach aufgebaute Vorrichtung kann selbstverständlich modifiziert werden. So kann es beispielsweise vorteilhaft sein, wenn die Bohrung, in welche die Stange beim Verriegeln eingreift, sich in Eingriffsrichtung konisch öffnet, so daß ein erleichtertes Einfädeln der Stange möglich ist. Ferner ist es selbstverständlich auch denkbar, die Verriegelungspunkte anders anzuordnen. Zu diesem Zweck könnte beispielsweise eine Umlenkvorrichtung vorgesehen sein. Ferner ist es denkbar, eine Verriegelungsvorrichtung vorzusehen, die beispielsweise durch einen Drehknopf, der an der Kühlschranktüre vorgesehen ist, betätigt wird. Mit diesem Drehknopf können Verriegelungselemente betätigt werden, die wiederum an zwei Verriegelungspositionen in entsprechende Aussparungen am Kühlschrankgehäuse angreifen. Bei diesen Verriegelungselementen kann es sich beispielsweise um hakenartige Elemente handeln, die um eine Achse drehbar gelagert sind.The described relatively simply constructed device can of course be modified. For example, it can be advantageous if the bore into which the Rod engages when locking, opens conically in the direction of engagement, so that easier threading of the rod is possible. Furthermore, it is of course also conceivable to arrange the locking points differently. A deflection device could be provided for this purpose, for example. It is also conceivable to provide a locking device which is actuated, for example, by a rotary knob which is provided on the refrigerator door. This rotary knob can be used to actuate locking elements, which in turn engage at two locking positions in corresponding cutouts on the refrigerator housing. These locking elements can, for example, be hook-like elements which are rotatably mounted about an axis.

Insbesondere das Vorsehen von zwei Befestigungspunkten, die vorzugsweise einander gegenüberliegend angeordnet sind, erlaubt in vorteilhafter Weise die Herstellung einer einfachen und kostengünstigen Vorrichtung, die ein sicheres Verriegeln der Kühlschranktür auch unter extremen Bedingungen, wie bei Unfällen, gewährleistet.In particular, the provision of two fastening points, which are preferably arranged opposite one another, advantageously allows the production of a simple and inexpensive device which ensures secure locking of the refrigerator door even under extreme conditions, such as in the event of an accident.

An exemplary embodiment of the invention is described below with reference to the accompanying drawings. Show here:
Fig. 1
is a schematic side sectional view of an inventive locking device in the unlocked state;
Fig. 2
is a schematic side sectional view of FIG. 1, wherein the locking device is in the locked state, and
Fig. 3
a partial sectional view of a further embodiment of a locking device according to the invention.

Fig. 1 zeigt eine schematische Seitenschnittansicht eines allgemein mit Bezugszeichen 1 versehenen Kühlschranks, insbesondere zur Verwendung in Kraftfahrzeugen. Erkennbar ist ein Gehäuse 2, welches an einem an der Oberkante vorgesehenen ersten Vorsprung 3 einen zylindrischen Stift 4 trägt. Der zylindrische Stift 4 umfaßt an seinem oberen Ende einen konisch sich erweiternden Kopf 5. Der zylindrische Stift 4 ist in dem ersten Vorsprung in einer hierin vorgesehenen Bohrung verschiebbar aufgenommen. Ferner ist an der Vorderseite des Gehäuses 2 eine Kühlschranktüre 6 vorgesehen, welche mit einem Dichtungsgummi 7 am Gehäuse anliegt. Die Kühlschranktüre 6 umfaßt eine Stange 8, welche in Führungen 9 verschiebbar aufgenommen ist. Die Stange 8 umfaßt ferner einen Absatz 10 gegen die eine Druckfeder 11 vorgespannt ist. In axialer Fortsetzung der Stange 8 ist an der Unterkante des Gehäuses 2 ein sich hiervon erstreckender zweiter Vorsprung 12 vorgesehen, welcher eine Bohrung 13 umfaßt.1 shows a schematic side sectional view of a refrigerator which is generally provided with reference number 1, in particular for use in motor vehicles. A housing 2 can be seen, which carries a cylindrical pin 4 on a first projection 3 provided on the upper edge. The cylindrical pin 4 comprises at its upper end a conically widening head 5. The cylindrical pin 4 is slidably received in the first projection in a bore provided therein. Furthermore, a refrigerator door 6 is provided on the front of the housing 2, which rests on the housing with a sealing rubber 7. The refrigerator door 6 comprises a rod 8 which is slidably received in guides 9. The rod 8 further comprises a shoulder 10 against which a compression spring 11 is biased. In the axial continuation of the rod 8, a second projection 12 extending therefrom is provided on the lower edge of the housing 2 and comprises a bore 13.

Die Funktion der erfindungsgemäßen Vorrichtung wird insbesondere in Zusammensicht der Fig. 1 und Fig. 2 deutlich. Hierbei ist die Verriegelungsvorrichtung im verriegelten Zustand dargestellt. Der zylindrische Stift 4 wird zu diesem Zweck durch Druck auf den Knopf 5 bis zum Anschlag an dem ersten Vorsprung 3 heruntergedrückt. Der zylindrische Stift 4 greift somit in die für die Stange 8 in der Türe vorgesehene Führung 9 ein. Gleichzeitig wird die in axialer Fortsetzung des zylindrischen Stifts 4 verschiebbar aufgenommene Stange 8 nach unten gedrückt, so daß ihr unteres Ende gegen die Wirkung der Druckfeder 11 nunmehr über die Unterkante der Kühlschranktüre 6 hinausragt und in die Bohrung 13 des zweiten Vorsprunges 12 einfädelt. Somit ist eine sichere Verriegelung der Kühlschranktüre 6 an zwei Verriegelungspunkten, nämlich am ersten Vorsprung 3 und am zweiten Vorsprung 12 gewährleistet.The function of the device according to the invention is particularly clear in the view of FIGS. 1 and 2. Here, the locking device is shown in the locked state. For this purpose, the cylindrical pin 4 is pressed down until the stop on the first projection 3 by pressing the button 5. The cylindrical pin 4 thus engages in the guide 9 provided for the rod 8 in the door. At the same time, the rod 8, which is slidably received in the axial continuation of the cylindrical pin 4, is pressed downward, so that its lower end now protrudes against the action of the compression spring 11 beyond the lower edge of the refrigerator door 6 and is threaded into the bore 13 of the second projection 12. This ensures secure locking of the refrigerator door 6 at two locking points, namely on the first projection 3 and on the second projection 12.

Fig. 3 zeigt eine weitere Ausgestaltungsform der erfindungsgemäßen Entriegelungsvorrichtung. Im Gegensatz zu dem in Fig. 1 und Fig. 2 gezeigten Ausführungsbeispiel ist hier die Vorderansicht eines Kühlgeräts in teilweiser Schnittansicht gezeigt. Insbesondere ist hier die Stange 8 in einem sich im wesentlichen über die Gesamthöhe der Kühlschranktüre 6 erstreckenden Führungsrohr 9 aufgenommen. Das Führungsrohr selbst ist in entsprechenden Aufnahmen 14, welche in der Kühlschranktüre vorgesehen sind, befestigt. Ferner ist in diesem Ausführungsbeispiel der Absatz 10 durch eine stufenartig vorgesehene verjüngte Stange 8 an ihrem unteren Ende ausgebildet.3 shows a further embodiment of the unlocking device according to the invention. In contrast to the exemplary embodiment shown in FIGS. 1 and 2, here is the front view of a refrigerator shown in partial sectional view. In particular, the rod 8 is received in a guide tube 9 which extends essentially over the entire height of the refrigerator door 6. The guide tube itself is fastened in corresponding receptacles 14, which are provided in the refrigerator door. Furthermore, in this embodiment, the shoulder 10 is formed by a step-like tapered rod 8 at its lower end.
