Description

Die vorliegende Erfindung ist im unabhängigen Anspruch 1 offenbart.The present invention is disclosed in independent claim 1.

Derartige Kühl- und/oder Gefriergeräte sind als sogenannte French-Door-Geräte bekannt. Bei diesem Gerät haben die genannten Dichtungen die Aufgabe, den Bereich zwischen den beiden gegensinnig öffnenden Türen abzudichten. Darüber hinaus sind üblicherweise Dichtungen vorgesehen, die den Bereich zwischen dem Korpus und der Tür abdichten.Such refrigerators and / or freezers are known as so-called French-door devices. In this device, the said seals have the task of sealing the area between the two opposing opening doors. In addition, seals are usually provided which seal the area between the body and the door.

Im geschlossenen Zustand beider Türen liegen die zwischen den Türen befindlichen Dichtungen üblicher Weise derart aneinander an, dass die gewünschte Abdichtfunktion erreicht wird bzw. ein Wärmeeintrag in den gekühlten Innenraum durch einen Bereich zwischen den Türen weitgehend oder vollständig verhindert wird. Das Dokument DE1709409U offenbart alle technischen Merkmale aus dem Oberbegriff des unabhängigen Anspruchs 1.In the closed state of both doors, the seals located between the doors are usually in such a way to each other that the desired sealing function is achieved or a heat input into the cooled interior is largely or completely prevented by an area between the doors. The document DE1709409U discloses all the technical features of the preamble of independent claim 1.

Ein Problem bei derartigen Geräten besteht darin, dass es beim Öffnen einer Tür sowie beim Schließen einer Tür unter Umständen zu einer Reibung der Dichtungen aneinander kommt, die zum einen das Öffnen und Schließen der Tür erschwert und zum anderen insofern unerwünscht ist, als dass sich dies negativ auf die Lebensdauer der Dichtungen auswirken kann. Wesentlich ist es somit, dass die genannten Türdichtungen im geschlossenen Zustand der Türen die gewünschte Dichtfunktion zwischen den Türen übernehmen, sobald aber eine Tür geöffnet oder geschlossen wird, diesen Schließvorgang bzw. Öffnungsvorgang möglichst nicht behindern dürfen. Dies hätte insbesondere bei der Verwendung von Selbstschließsystemen Nachteile, da diese keine großen Schließkräfte aufweisen, so dass es unter Umständen dazu kommen kann, dass eine Tür nicht richtig schließt.A problem with such devices is that when opening a door as well as when closing a door under certain circumstances, a friction of the seals comes together, on the one hand makes it difficult to open and close the door and the other is undesirable in that this is can negatively affect the life of the seals. It is therefore essential that the said door seals in the closed state of the doors take over the desired sealing function between the doors, but as soon as a door is opened or closed, this closing operation or opening operation should not hinder as possible. This would have disadvantages, especially when using self-closing systems, since they do not have large closing forces, so that under some circumstances a door may not close properly.

Der vorliegenden Erfindung liegt somit die Aufgabe zugrunde, ein Kühl- und/oder Gefriergerät der eingangs genannten Art dahingehend weiterzubilden, dass ein möglichst leichtes Schließen und Öffnen der Türen gewährleistet ist.The present invention is therefore the object of developing a refrigerator and / or freezer of the type mentioned in such a way that the easiest possible closing and opening the doors is guaranteed.

Diese Aufgabe wird durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der Erfindung sind offenbart in den abhängigen Ansprüchen.This object is achieved by a refrigerator and / or freezer with the features of claim 1. Further embodiments of the invention are disclosed in the dependent claims.

Danach ist vorgesehen, dass die Dichtung wenigstens einer Tür in eine zweite Position bewegbar ist, in der sie zu der Dichtung der anderen Tür zumindest bereichsweise einen größeren Abstand aufweist, als in der ersten Position der Dichtungen. Des weiteren ist wenigstens eine Nocke vorgesehen, die derart angeordnet ist, dass sie beim Öffnen und Schließen der Tür bewegt wird. Diese Nocke steht sowohl mit der Tür als auch mit der Dichtung so Verbindung, dass sie die Dichtung von ihrer ersten in ihre zweite Position bewegt, wenn die Tür ausgehend von der Schließstellung geöffnet wird. Erreicht die Tür ihre Schließstellung, wird die Dichtung vorzugsweise durch die Nocke von der zweiten in die erste Position bewegt. Die Nocke ist somit derart angeordnet, dass sie bewegt wird, wenn zumindest eine der Türen des Gerätes aus ihrer Schließstellung heraus geöffnet wird oder aus einer Offenstellung in die Schließstellung bewegt wird.Thereafter, it is provided that the seal of at least one door is movable to a second position in which it at least partially has a greater distance from the seal of the other door, as in the first position of the seals. Furthermore, at least one cam is provided, which is arranged so that it is moved when opening and closing the door. This cam communicates with both the door and the gasket so as to move the gasket from its first to its second position when the door is opened from the closed position. When the door reaches its closed position, the seal is preferably moved by the cam from the second to the first position. The cam is thus arranged so that it is moved when at least one of the doors of the device is opened from its closed position or moved from an open position to the closed position.

Diese Nocke erfährt somit eine Bewegung, die sie in geeigneter Weise auf die betreffende Türdichtung überträgt. Dabei stehen die Nocke und die Dichtung vorzugsweise so miteinander in Verbindung, dass die Nocke bei Erreichen in der Schließstellung der Türen die Dichtung in ihre erste Position bewegt, in der sie dichtend mit der Dichtung der anderen Türe in Verbindung steht. Wird eine oder beide der Türen ausgehend von dieser Position geöffnet, kommt es unmittelbar mit Beginn des Öffnungsvorgangs oder zumindest ab einem bestimmten Öffnungswinkel der Tür zu einer Bewegung der Nocke(n) und somit auch zu einer Bewegung der Dichtung(en) derart, dass die Dichtung(en) ausgehend von ihrer ersten in die zweite Position bewegt wird/werden, in der sie einen größeren Abstand zueinander aufweisen als im Zustand zweier geschlossener Türen.This cam thus undergoes a movement which transfers it in a suitable manner to the relevant door seal. Preferably, the cam and the seal are in communication with each other such that the cam, when it reaches the closed position of the doors, moves the seal to its first position in which it sealingly communicates with the seal of the other door. If one or both of the doors is opened starting from this position, immediately at the beginning of the opening process or at least at a certain opening angle of the door, a movement of the cam (s) occurs and thus also a movement of the seal (s) such that the Seal (s) is moved from its first to the second position in which they have a greater distance from each other than in the state of two closed doors.

Entsprechend bewirkt die Nocke, dass zumindest eine Dichtung der Tür von der anderen Dichtung wegbewegt wird, wenn zumindest eine Tür geöffnet wird. Vorzugsweise ist vorgesehen, dass die Dichtungen und Nocken beider Türen bewegt werden, wenn ausgehend von der geschlossenen Position beider Türen eine oder beide Türen geöffnet werden. Auf diese Weise ist es möglich, eine Tür des Gerätes mit geringem Kraftaufwand zu öffnen und zu schließen. Zudem wird sichergestellt, dass es zu keiner oder nur zu einer geringen Reibung zwischen den Dichtungen kommt, wenn eine Tür geöffnet und geschlossen wird.Accordingly, the cam causes at least one seal of the door to be moved away from the other seal when at least one door is opened. It is preferably provided that the seals and cams of both doors are moved when starting from the closed position of both doors one or both doors are opened. In this way, it is possible to open a door of the device with little effort and close. In addition, it ensures that there is no or only a slight friction between the seals when a door is opened and closed.

Erfindungsgemäß ist vorgesehen, dass die Dichtung derart angeordnet ist, dass sie um eine Achse verschwenkbar ist. Denkbar ist somit beispielsweise, dass an der Tür bzw. an einem Türprofil eine Aufnahme vorgesehen ist, in der die Dichtung in einem Bereich aufgenommen ist und zwar derart, dass sie in dieser Aufnahme schwenkbar bzw. drehbar aufgenommen ist.According to the invention it is provided that the seal is arranged such that it can be pivoted about an axis. It is thus conceivable, for example, that a receptacle is provided on the door or on a door profile, in which the seal in a Area is received in such a way that it is pivotally or rotatably received in this recording.

Des weiteren ist vorzugsweise vorgesehen, dass die Nocke derart angeordnet ist, dass sie um eine Achse verschwenkbar ist. Somit ist es möglich, dass auch die Nocke verschwenkbar bzw. drehbar angeordnet ist. Diese Verschwenkbewegung führt die Nocke aus, wenn eine Tür oder beide Türen ausgehend von der geschlossenen Position beider Türen geöffnet wird oder geschlossen wird. Die Schwenkbewegung der Nocke wird aufgrund der Verbindung zwischen Nocke und Dichtung dahingehend auf die Dichtung übertragen, dass diese ebenfalls eine Schwenkbewegung ausführt, durch die die Dichtung beim Öffnen der Tür in ihre zweite Position, d.h. in eine Parkposition bewegt wird.Furthermore, it is preferably provided that the cam is arranged such that it is pivotable about an axis. Thus, it is possible that the cam is arranged pivotable or rotatable. This pivotal movement executes the cam when a door or both doors are opened or closed from the closed position of both doors. The pivoting movement of the cam is transmitted to the seal due to the connection between the cam and the seal, in that it also performs a pivotal movement whereby the seal, upon opening the door, is moved to its second position, i. is moved to a parking position.

Vorzugsweise ist vorgesehen, dass die Achse, um die die Nocke verschwenkbar ist, in ihrer Position veränderbar ist. Durch einen solchen veränderbaren Drehpunkt kann ein Türspalt zwischen den Türen mit variabler Größe abgedeckt werden. Denkbar ist es beispielsweise einen Türspalt abzudecken, der im Bereich zwischen 6 und 9 mm, ggf. + 1 mm Dichtungseigenhub liegt.It is preferably provided that the axis about which the cam is pivotable, in its position is variable. By such a variable pivot point, a door gap between the variable-sized doors can be covered. It is conceivable, for example, to cover a door gap which lies in the range between 6 and 9 mm, if necessary + 1 mm Dichtseigenhub.

In weiterer Ausgestaltung der Erfindung ist es denkbar, dass die Nocke fest mit der Dichtung in Verbindung steht. Dabei ist des weiteren vorzugsweise vorgesehen, dass Nocke und Dichtung einen gemeinsamen Drehpunkt aufweisen, das heißt um eine gemeinsame Achse verschwenkbar bzw. verdrehbar sind.In a further embodiment of the invention, it is conceivable that the cam is firmly connected to the seal. In this case, it is further preferably provided that the cam and the seal have a common pivot point, that is, are pivotable or rotatable about a common axis.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass sich die Nocke in ihrer ersten Position befindet, wenn die Tür geschlossen ist und sich in ihrer zweiten Position befindet, wenn die Tür ausgehend von dieser Position geöffnet ist. Weiterhin kann vorgesehen sein, dass die Nocke und die Dichtung so miteinander in Verbindung stehen, dass die Nocke die Dichtung von ihrer ersten in ihre zweite Position bewegt, wenn die Nocke ihrerseits von ihrer ersten in die zweite Position bewegt wird.In a further embodiment of the invention it is provided that the cam is in its first position when the door is closed and is in its second position when the door is opened starting from this position. Furthermore, it can be provided that the cam and the seal are in communication with each other so that the cam moves the seal from its first to its second position when the cam is in turn moved from its first to the second position.

Grundsätzlich kann vorgesehen sein, dass die Nocke derart angeordnet ist, dass sie zumindest in ihrer zweiten Position über die Stirnseite der Tür hinausragt und/oder in ihrer zweiten Position zumindest mit ihrem Kontaktbereich weiter von der Tür wegbewegt ist als in ihrer ersten Position.In principle, it can be provided that the cam is arranged such that it protrudes beyond the front side of the door at least in its second position and / or is moved further away from the door in its second position at least with its contact area than in its first position.

Die Nocke kann wenigstens einen Kontaktabschnitt aufweisen, mit dem die Nocke im geschlossenen Zustand der Türen mit einem weiteren Element, vorzugsweise mit der Nocke der anderen Tür in Kontakt steht. Beim Öffnen einer Tür verläßt die Nocke ab einem bestimmten Öffnungswinkel ihre Kontaktstellung, das heißt der Kontaktabschnitt steht dann nicht mehr mit einem weiteren Element, wie z.B. mit dem Kontaktabschnitt der Nocke der anderen Tür in Verbindung. Ab diesem Zeitpunkt befindet sich die Nocke, vorzugsweise die Nocken und Dichtungen beider Türen in ihrer zweiten Position.The cam may have at least one contact portion, with which the cam in the closed state of the doors is in contact with a further element, preferably with the cam of the other door. When opening a door leaves the cam from a certain opening angle their contact position, that is, the contact portion is then no longer with another element, such as. communicates with the contact portion of the cam of the other door. From this point on, the cam, preferably the cams and seals of both doors, is in its second position.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass sich zwischen dem Kontaktabschnitt der Nocke und dem Bereich, in dem die Nocke mit der Dichtung in Verbindung steht, die Achse befindet, um die die Nocke verschwenkbar ist.In a further embodiment of the invention it is provided that between the contact portion of the cam and the region in which the cam is in communication with the seal, the axis is about which the cam is pivotable.

In weiterer Ausgestaltung der Erfindung ist wenigstens eine Feder vorgesehen, die auf die Nocke und/oder direkt auf die Dichtung eine Kraft ausübt. Diese Feder kann einerseits an der Tür bzw. an einem Türprofil angeordnet sein und andererseits mit der Nocke zusammenwirken. Vorzugsweise ist die Feder so angeordnet, dass die Nocke in Richtung auf ihre zweite Position mit einer Kraft beaufschlagt wird.In a further embodiment of the invention, at least one spring is provided, which exerts a force on the cam and / or directly on the seal. This spring can be arranged on the one hand on the door or on a door profile and on the other hand cooperate with the cam. Preferably, the spring is arranged so that the cam is acted upon in the direction of its second position with a force.

Figur 1 zeigt mit dem Bezugszeichen 10, 10' zwei Türen eines French-Door-Gerätes, die gegensinnig zueinander geöffnet werden können. Die Türen sind jeweils mit ihrem nicht dargestellten Seitenbereich an dem Korpus des Gerätes angelenkt. FIG. 1 shows by the reference numeral 10, 10 'two doors of a French-door device, which can be opened in opposite directions to each other. The doors are each articulated with their side area, not shown, on the body of the device.

Wie dies aus Figur 1 weiter hervorgeht, bestehen die Türen jeweils aus einer Außentür bzw. einem Außenbereich 12, 12', beispielsweise aus Metall bzw. Blech, und einer Innentür bzw. einem Innenbereich 14, 14'. An diesem Innenbereich 14, 14' sind beispielsweise ein oder mehrere Türabsteller befestigbar.Like this FIG. 1 Furthermore, the doors each consist of an outer door or an outer area 12, 12 ', for example made of metal or sheet metal, and an inner door or an inner area 14, 14'. For example, one or more door racks can be fastened to this inner region 14, 14 '.

Mit den Bezugszeichen 200, 200' sind umlaufende Magnettürdichtungen gekennzeichnet, die jeweils eine dichte Verbindung zwischen Tür und Korpus sicherstellen.With the reference numerals 200, 200 'circumferential magnetic door seals are marked, each ensuring a tight connection between the door and the body.

In den zueinander gewandten Bereichen der Türen 10, 10' sind diese mit jeweils einer oder mehreren, vorzugsweise mit zwei oder mehr in Höhenrichtung der Türen beabstandeten Nocken 30, 30' ausgeführt. Wie dies aus Figur 1 ersichtlich ist, stehen die Nocken 30, 30' über die zueinander gewandten Stirnseiten der jeweiligen Türen 10, 10' hinaus.In the mutually facing areas of the doors 10, 10 ', these are each designed with one or more cams 30, 30' preferably spaced apart in the height direction of the doors, preferably two or more. Like this FIG. 1 it can be seen, the cams 30, 30 'on the mutually facing end faces of the respective doors 10, 10' addition.

Wie dies insbesondere aus Figur 3 hervorgeht, sind die Nocken 30, 30' schwenkbar an der Tür angeordnet. Mit dem Bezugszeichen 32 ist in Figur 3 die entsprechende Schwenkachse der Nocke 30 gekennzeichnet. Des Weiteren weist die Nocke 30 den aus Figur 1 ersichtlichen Kontaktabschnitt 34 auf, mit dem die Nocke 30 beim Bewegen der Tür in ihre Schließstellung ab Unterschreiten eines bestimmten Öffnungswinkels mit einem weiteren Element, vorzugsweise mit der Nocke 30' der jeweils anderen Tür 10' in Verbindung tritt.How this particular out FIG. 3 As can be seen, the cams 30, 30 'are pivotally mounted on the door. The reference numeral 32 is in FIG. 3 the corresponding pivot axis of the cam 30 marked. Furthermore, the cam 30 has the FIG. 1 apparent contact portion 34, with the cam 30 when moving the door in its closed position from below a certain opening angle with another element, preferably with the cam 30 'of the other door 10' comes into contact.

Figur 3 zeigt die Tür 10 eines French-Door-Gerätes, dessen andere Tür 10' geöffnet ist. FIG. 3 shows the door 10 of a French door device, the other door 10 'is open.

Mit dem Bezugszeichen 36 ist ein Befestigungsabschnitt, beispielsweise ein Bolzen oder dergleichen der Nocke 30 gekennzeichnet, der wie aus Figur 3 ersichtlich in einem Aufnahmebereich 22 der Dichtung 20 aufgenommen ist. Dieser Abschnitt 36 der Nocke 30 dient somit gleichsam als Mitnehmer und bewirkt, dass die Dichtung 20 bewegt wird, wenn die Nocke 30 ihrerseits eine Bewegung erfährt.By the reference numeral 36, a fixing portion, for example, a bolt or the like of the cam 30 is characterized, as shown FIG. 3 can be seen in a receiving area 22 of the seal 20 is added. This portion 36 of the cam 30 thus serves as a driver and causes the seal 20 is moved when the cam 30 in turn undergoes a movement.

Die Dichtung 20 einer oder beider Türen 10, 10' ist vorzugsweise als Extrusionsprofil ausgeführt und weist einen weicheren Teil und einen demgegenüber härten Teil auf. Der weichere Teil der Dichtung 20 ist mit dem Bezugszeichen 24 gekennzeichnet und dient vorzugsweise als Abdichtungsteil, der eine dichtende Verbindung zu der Dichtung 20' der anderen Tür bildet. In diesem Teil der Dichtung kann auch wenigstens eine Kammer 25 angeordnet sein, in der sich ein Magnet befinden kann, der in Wechselwirkung mit der entsprechend ausgebildeten Dichtung 20' der anderen Tür 10' diese anzieht und so eine dichte Verbindung zwischen den Türen sicherstellt.The seal 20 of one or both doors 10, 10 'is preferably designed as an extrusion profile and has a softer part and a contrast hardening part. The softer part of the seal 20 is designated by the reference numeral 24 and preferably serves as a sealing part, which forms a sealing connection to the seal 20 'of the other door. In this part of the seal can also be arranged at least one chamber 25 in which there may be a magnet which, in interaction with the correspondingly formed seal 20 'of the other door 10' attracts them and thus ensures a tight connection between the doors.

Der demgegenüber härtere Teil der Dichtung 20 ist mit dem Bezugszeichen 26 gekennzeichnet und bildet eine Drehlagerung der Dichtung 20, die in Figur 3 ebenfalls mit dem Bezugszeichen 26 gekennzeichnet ist. Die Dichtung 20 ist somit um die Achse 26 drehbar gelagert. Auch die Aufnahme 22 der Dichtung 20 kann als härterer Teil der Dichtung 20 ausgebildet sein, da diese sicherstellen muß, dass die Dichtung 20 der Bewegung der Nocke 30 folgt.The harder part of the seal 20 is denoted by the reference numeral 26 and forms a pivot bearing of the seal 20, the in FIG. 3 also designated by the reference numeral 26. The seal 20 is thus rotatably mounted about the axis 26. Also, the receptacle 22 of the seal 20 may be formed as a harder part of the seal 20, since this must ensure that the seal 20 of the movement of the cam 30 follows.

Die Tür 10 kann in ihrer zu der anderen Tür 10' gewandten Seite ein Profil aufweisen, das mit dem Bezugszeichen 100 gekennzeichnet ist und das die Aufnahmen für den Abschnitt 26 der Dichtung 20 bildet und auch die Aufnahme für die Drehachse 32 der Nocke 30. Denkbar ist es auch, dass die Drehachse 32 Bestandteil des Türprofils 100 ist und mit der Nocke 30 bzw. mit einer Ausnehmung der Nocke 30 in Verbindung steht.In its side facing the other door 10 ', the door 10 may have a profile which is designated by the reference numeral 100 and which forms the receptacles for the section 26 of the seal 20 and also the receptacle for the axis of rotation 32 of the cam 30. Conceivable it is also that the rotation axis 32 part of the door profile 100 and is in communication with the cam 30 and with a recess of the cam 30.

Auch ist es denkbar, die Aufnahme für die Heizung zur Kondensatvermeidung in dieses Aufnahmeprofil 100 zu integrieren.It is also conceivable to integrate the receptacle for the heater for condensate avoidance in this receiving profile 100.

Auch ist es möglich, dass die Drehachsen bzw. die für die Drehachsen vorgesehenen Aufnahmen alternativ oder zusätzlich an einem oder mehreren Abdeckprofilen angeordnet sind, die z.B. die obere Abdeckung der Tür 10 bilden.It is also possible for the axes of rotation or the receptacles provided for the axes of rotation to be arranged alternatively or additionally on one or more covering profiles, which are e.g. form the top cover of the door 10.

Mit dem Bezugszeichen 40 ist in Figur 3 eine Feder gekennzeichnet, die ebenfalls in oder an dem Türprofil 100 und/oder in der genannten Abdeckung angeordnet ist.The reference numeral 40 is in FIG. 3 a spring, which is also arranged in or on the door profile 100 and / or in said cover.

Diese Feder 40 wirkt auf die Nocke 30 derart ein, dass diese mit ihrem Kontaktbereich 32 von der Tür 10 wegbewegt wird, und zwar in die Position, die in Figur 3 ersichtlich ist.This spring 40 acts on the cam 30 so that it is moved away with its contact portion 32 of the door 10, in the position that in FIG. 3 is apparent.

Grundsätzlich ist es denkbar, dass pro Tür 10, 10' zwei oder mehr als zwei Nocken 30 vorgesehen sind, die beispielsweise auf beiden Enden, d.h. in einem oberen Abschnitt der Dichtung 20 und in einem unteren Abschnitt der Dichtung 20 in diese eingreifen bzw. über den Abschnitt 22, 36 mit dieser in Verbindung stehen.In principle, it is conceivable that per door 10, 10 'two or more than two cams 30 are provided which, for example, on both ends, i. in an upper portion of the seal 20 and in a lower portion of the seal 20 engage in this or via the section 22, 36 in conjunction with this.

Der beschriebene Aufbau der Tür 10 gilt entsprechend für die in Figur 3 nicht dargestellte Tür 10', die die genannten Komponenten in spiegelbildlicher Anordnung aufweist.The described construction of the door 10 applies accordingly for in FIG. 3 not shown door 10 ', which has said components in a mirror image arrangement.

Figur 3 zeigt die Position der Nocke 30 sowie der Dichtung 20, in einem Zustand, in dem eine oder beide Türen geöffnet sind. In diesem Zustand wird der Kontaktbereich 34 der Nocke 30 durch die Kraft der Feder 40 von der Tür 10 weg, das heißt gemäß Figur 3 nach links bewegt. Dies führt zu einer Drehung der Nocke 30 im Uhrzeigersinn und zu einer Bewegung des Abschnittes 36 der Nocke 30 nach rechts. FIG. 3 shows the position of the cam 30 and the seal 20, in a state in which one or both doors are opened. In this state, the contact portion 34 of the cam 30 by the force of the spring 40 of the door 10 away, that is according to FIG. 3 moved to the left. This results in clockwise rotation of the cam 30 and movement of the portion 36 of the cam 30 to the right.

Diese Bewegung der Nocke 30 hat zur Folge, dass die Türdichtung 20 ausgehend von der Schließposition im Uhrzeigersinn und zwar um die Schwenkachse 26 gedreht bzw. verschwenkt wird, bis sie ihre in Figur 3 dargestellte Position erreicht hat. In dieser Position befindet sich die Dichtung 10 in ihrer erfindungsgemäß zweiten Position, in der sie zur Tür 10 hinbewegt ist.This movement of the cam 30 has the result that the door seal 20 is rotated or pivoted starting from the closed position in the clockwise direction about the pivot axis 26 until they turn their in FIG. 3 has reached the position shown. In this position, the seal 10 is in its second position according to the invention, in which it is moved toward the door 10.

Wie dies oben dargestellt wurde, werden die Nocken 30, 30' sowohl bei der geöffneten Türe 10' als auch bei der geschlossenen Türe 10 durch die Federspannung aus der jeweiligen Aufnahme der Türen 10, 10' geschoben. Durch die entsprechende Lagerung der Nocken 30, 30' in den Aufnahmeteilen des Profils 100 und den Eingriff in die Aufnahme 22 des French-Door-Koextrusionsprofils werden die Dichtungen 10, 10' dadurch in die jeweilige Parkposition, das heißt in die zweite Position geschoben. Durch diese zweite Position ist gewährleistet, dass sich keine Störkontur im Bereich der geschlossenen Tür 10 während des Schließvorgangs der Tür 10' befindet.As was shown above, the cams 30, 30 ', both in the open door 10' and in the closed door 10 by the spring tension from the respective receiving the doors 10, 10 'are pushed. By the corresponding mounting of the cams 30, 30 'in the receiving parts of the profile 100 and the engagement in the receptacle 22 of the French-door coextrusion profile, the seals 10, 10' thereby in the respective parking position, that is pushed into the second position. This second position ensures that there is no interference contour in the area of the closed door 10 during the closing operation of the door 10 '.

Dies hat den Vorteil, dass die jeweilige Tür 10' ohne Dichtungsreibung geschlossen werden kann. Kurz bevor die Tür 10' ganz geschlossen ist berühren sich die Nocken 30, 30' gegenseitig und werden in die Aufnahmeteile bzw. Aufnahmebereiche der Türen 10, 10' geschoben. Das heißt die Nocken 30, 30' verdrängen sich in diesem Fall gegenseitig.This has the advantage that the respective door 10 'can be closed without seal friction. Just before the door 10 'is fully closed, the cams 30, 30' touch each other and are pushed into the receiving parts or receiving areas of the doors 10, 10 '. That is, the cams 30, 30 'displace each other in this case.

Wird die Tür 10' somit ausgehend von der in Figur 1 dargestellten Position geschlossen, tritt der Kontaktbereich 34 der Nocke 30 ab einem bestimmten Schließwinkel der Tür 10 mit der Nocke 30' bzw. mit deren Kontaktbereich der anderen Tür 10' in Verbindung, was dazu führt, dass die in Figur 3 dargestellte Nocke 30 gegen den Uhrzeigersinn um die Achse 32 verschwenkt wird. Dies wiederum führt dazu, dass die Dichtung 20, die über die Elemente 22, 36 mit der Nocke 30 in Verbindung steht, von der in Figur 3 dargestellten zweiten Position gegen den Uhrzeigersinn in die erste Position verschwenkt wird. Ein entsprechender Vorgang vollzieht sich bei beiden Türen, d.h. bei der geschlossenen sowie auch bei der zu schließenden Tür 10, 10'.If the door 10 'thus starting from the in FIG. 1 closed position, the contact portion 34 of the cam 30 occurs from a certain closing angle of the door 10 with the cam 30 'or with the contact region of the other door 10' in connection, which leads to the in FIG. 3 shown cam 30 is pivoted counterclockwise about the axis 32. This, in turn, causes the seal 20, which is in communication with the cam 30 via the elements 22, 36, to be inferior to that in FIG FIG. 3 shown second position is pivoted counterclockwise in the first position. A corresponding process takes place two doors, ie in the closed as well as in the door to be closed 10, 10 '.

Dies bedeutet, dass die Dichtungen 20, 20' über deren Drehpunkte 26 ausgelenkt werden und sich aufeinander zu bewegen, bis sich die Dichtungen 20,20' berühren und den Türspalt abdichten.This means that the seals 20, 20 'are deflected over their pivot points 26 and move towards each other until the seals 20, 20' touch and seal the door gap.

Denkbar ist es, dass die Dichtungen einen kleinen Hubbereich von +/- 1mm aufweisen, um eine Beschädigung zu vermeiden bzw. um eventuelle Toleranzen auszugleichen. Besonders vorteilhaft ist es, wenn das Nockensystem insofern flexibel ausgeführt ist, dass die Nocken 30, 30' einen veränderbaren Drehpunkt 32 aufweisen. Dadurch kann ein variabler Türspalt abgedeckt werden. Denkbar ist es beispielsweise einen Türspalt in der Größenordnung von 6 - 9 mm + 1 mm Dichtungseigenhub abzudecken.It is conceivable that the seals have a small stroke range of +/- 1 mm in order to avoid damage or to compensate for any tolerances. It is particularly advantageous if the cam system is designed to be flexible in that the cams 30, 30 'have a variable pivot point 32. As a result, a variable door gap can be covered. It is conceivable, for example, a door gap in the order of 6 - 9 mm + 1 mm Dichtseigenhub cover.

Figur 2 zeigt die Position der Nocken 30, 30' sowie der Dichtung 20, 20', in dem Zustand, in dem beide Türen 10, 10' geschlossen sind. In diesem Zustand stehen die beiden Nocken 30, 30' mit ihren jeweiligen Kontaktbereichen 34 miteinander in Verbindung. Jede der Nocken 30, 30' wird somit durch die jeweils andere Nocke 30, 30' entgegen der Kraft der Feder 40 eingedrückt, d.h. zu der jeweiligen Tür 10, 10' hinbewegt, was dazu führt, dass die beiden Dichtungen 20, 20' durch Verschwenken aufeinander zu bewegt werden, so dass eine dichtende Verbindung zwischen den Türen vorliegt. Dieser Zustand ergibt sich beispielsweise aus Figur 2. In dieser Figur ist die rechte Tür 10 geschnitten dargestellt. Aus Figur 2 geht bei der rechten Tür 10 die untere Nocke 30 hervor, die über die Feder 40 gemäß Figur 2 nach links vorgespannt wird. FIG. 2 shows the position of the cams 30, 30 'and the seal 20, 20', in the state in which both doors 10, 10 'are closed. In this state, the two cams 30, 30 'communicate with each other with their respective contact regions 34. Each of the cams 30, 30 'is thus pressed by the respective other cam 30, 30' against the force of the spring 40, that is, to the respective door 10, 10 'moves, resulting in that the two seals 20, 20' through Pivoting are moved toward each other, so that there is a sealing connection between the doors. This condition arises for example FIG. 2 , In this figure, the right door 10 is shown cut. Out FIG. 2 goes in the right door 10, the lower cam 30 out, the spring 40 according to FIG. 2 biased to the left.

Wird eine der Türen 10, 10' oder werden beide Türen 10, 10' ausgehend von Figur 2 geöffnet, führt dies dazu, dass die Nocken 30, 30' beider Türen 10, 10' mit zunehmendem Öffnungswinkel aufgrund der Federkraft weiter von der jeweiligen Tür 10, 10' weg bewegt werden, wobei beispielsweise die in Figur 3 dargestellte Nocke 30 eine Drehbewegung im Uhrzeigersinn erfährt. Dies führt dazu, dass die Dichtung 20 um die Achse 26 ebenfalls im Uhrzeigersinn bewegt wird. Somit werden die beiden Türdichtungen 20, 20' voneinander wegbewegt.If one of the doors 10, 10 'or both doors 10, 10' starting from FIG. 2 open, this leads to the fact that the cams 30, 30 'of both doors 10, 10' are moved further away from the respective door 10, 10 'as the opening angle increases due to the spring force, wherein, for example, the in FIG. 3 shown cam 30 undergoes a clockwise rotation. This causes the seal 20 is also moved about the axis 26 in a clockwise direction. Thus, the two door seals 20, 20 'are moved away from each other.

Wird somit eine Tür geöffnet verläßt deren Nocke ab einem bestimmten Öffnungswinkel die Kontaktstellung zu der anderen Nocke und wird durch die Kraft der Feder in deren zweite Position bewegt. Dies führt dazu, dass die Nocke die Dichtung in ihre zweite Position, das heißt in ihre Parkposition bewegt. Dies gilt nicht nur für die geöffnete Tür, sondern auch für die Tür, die geschlossen bleibt.Thus, if a door is opened leaving its cam from a certain opening angle, the contact position with the other cam and is moved by the force of the spring in its second position. This causes the cam to move the seal to its second position, that is, to its parking position. This is true not only for the open door, but also for the door that remains closed.

Als Vorteile sind zu nennen, dass das Schließen einer Tür ohne Kollisionsgefahr zwischen Dichtung und Gegentür leicht möglich ist. Dies hat größere Vorteile insbesondere bei der Verwendung von Türschließsystemen. Die vorliegende Erfindung betrifft somit auch ein Kühl- und/oder Gefriergerät mit einem derartigen Türschließsystem.As advantages are to be mentioned that the closing of a door without risk of collision between the seal and the opposite door is easily possible. This has greater advantages, especially when using door locking systems. The present invention thus also relates to a refrigerator and / or freezer with such a door closing system.

Denkbar ist es weiterhin, das Heizungskabel nicht mehr in der Dichtung zu integrieren, sondern im Aufnahmeprofil, wodurch sich der Montage- und Serviceaufwand verringert und eine mögliche Störkontur durch das Kabel in der Dichtung entfällt. Ein weiterer Vorteil ist ein geringer Eigenhub der Dichtung und ein dadurch reduziertes Walkverhalten der Dichtung, wodurch sich die Tür leicht Öffnen lässt.It is also conceivable to integrate the heating cable no longer in the seal, but in the receiving profile, which reduces the assembly and service costs and eliminates a possible interference contour through the cable in the seal. Another advantage is a low self-stroke of the seal and thereby reduced Walk behavior of the seal, which makes the door easy to open.
