A lateral edge (5-11) of the outer plate is reinforced by at least one section (6, 7, 18, 20) bent away from the lateral flank (3) towards the inside of the door, at a distance from the outer side and the inner side of the door.

Description

Tür für ein Kältegerät Door for a refrigeration appliance
Die vorliegende Erfindung betrifft eine Tür für ein Kältegerät mit einer mit Isolationsmaterial ausgeschäumten äußeren Hülle. Beim Ausschäumen der Hülle treten erhebliche Drücke auf, die, auch wenn die Hülle während des Ausschäumens äußerlich abgestützt wird, nach dem Aushärten des Isolierschaums zu dauerhaften Verformungen von Oberflächen der Tür führen können. Um die Gefahren derartiger Verformungen an den großflächigen Außenseiten der Türen zu vermeiden, ist es gebräuchlich, die Außenseiten einteilig aus einer leicht bombierten Blechblatte zu fertigen. Einerseits verbessert die Bombierung die Steifigkeit des Blechs auch bei geringer Material stärke, zum anderen sind an einer solchen Fläche leichte Verformungen, falls sie denn auftreten sollten, wesentlich weniger auffällig als an einer planen Oberfläche.The present invention relates to a door for a refrigerator with a foamed with insulating material outer shell. When foaming the shell considerable pressures occur, which, even if the shell is externally supported during foaming, can lead to permanent deformation of surfaces of the door after curing of the insulating foam. In order to avoid the dangers of such deformations on the large-scale outer sides of the doors, it is customary to manufacture the outsides in one piece from a slightly cambered sheet metal sheet. On the one hand, the crowning improves the rigidity of the sheet even with low material strength, on the other hand are on such a surface slight deformations, if they should occur, much less noticeable than on a flat surface.
An den Seitenflanken der Türen ist eine solche Lösung wenig praktikabel, da aufgrund ihrer geringen Breite eine wesentlich stärkere Krümmung der Oberfläche erforderlich wäre als an der Vorderseite, um eine ähnliche Versteifungswirkung zu erreichen. Dies führt dazu, dass häufig die seitlichen Flanken der gegen eine unerwünschte Verformung beim Ausschäumen empfindlichste Teil der Tür sind. Es ist daher wünschenswert, die Verformbarkeit der seitlichen Flanken mit einfachen, preiswerten Mitteln reduzieren zu können. Dies würde unter anderem die Möglichkeit eröffnen, ohne Einbuße an Stabilität dünnere und leichtere Bleche für die äußere Hülle einer solchen Tür zu verwenden.Such a solution is less practicable on the side flanks of the doors since, due to their small width, a much greater curvature of the surface would be required than on the front side in order to achieve a similar stiffening effect. As a result, the lateral flanks of the door which are most sensitive to undesired deformation during foaming are often the lateral flanks. It is therefore desirable to be able to reduce the deformability of the lateral flanks with simple, inexpensive means. This would, inter alia, open the possibility to use thinner and lighter sheets for the outer shell of such a door without sacrificing stability.
Dieses Ziel wird erfindungsgemäß erreicht, indem bei einer Kältegerätetür mit einer mit Isolationsmaterial ausgeschäumten äußeren Hülle, die eine eine Außenseite der Tür und wenigstens einen Teil von Seitenflanken der Tür einteilig überdeckende Außenplatte umfasst, ein seitlicher Rand der Außenplatte durch wenigstens einen beabstandet von Außen- und Innenseite der Tür von der Seitenflanke ins Innere der Tür hinein abgewinkelten Steg versteift ist. Ein solcher Steg kann zum Beispiel durch eine Falzverbindung zwischen einem seitlichen Rand einer Seitenflanke der Tür und einem seitlichen Rand von deren Außenlatte erzeugt sein.This object is achieved according to the invention by a case of a refrigerator door with a foamed with insulating outer shell, which comprises an outer side of the door and at least part of side edges of the door integrally covering outer plate, a lateral edge of the outer plate by at least one spaced from the outside and Inside the door is stiffened from the side edge into the inside of the door angled web. Such a web may be generated, for example, by a rabbet joint between a lateral edge of a side edge of the door and a lateral edge of its outer lip.
Die Wirksamkeit eines solchen Stegs ist am höchsten, wenn er im Wesentlichen parallel zur Außenseite der Tür ausgerichtet ist. Vorzugsweise ist der Steg einteiliger Bestandteil der Außenplatte.The effectiveness of such a web is highest when it is aligned substantially parallel to the outside of the door. Preferably, the web is an integral part of the outer panel.
Einer ersten Ausgestaltung zufolge kann die Außenplatte sich einstückig über die gesamte Seitenflanke erstrecken, d.h. sie reicht noch über den von der Innenseite der Tür beabstandeten Steg ein Stück weit nach hinten hinaus.According to a first embodiment, the outer plate may extend integrally over the entire side edge, i. it still extends beyond the bridge spaced from the inside of the door a little way to the rear.
Alternativ kann ein Profilelement, das zusammen mit der Außenplatte die Seitenflanke bildet, entlang des Stegs mit der Außenplatte verbunden sein. Die Verwendung eines solchen Profilelements ist auch unter ästhetischen Gesichtspunkten interessant, da sie die Möglichkeit eröffnet, unterschiedliche Materialien bzw. unterschiedlich aussehende Oberflächen an der Außenplatte und dem Profilelement zu verwenden.Alternatively, a profile element, which forms the side edge together with the outer plate, be connected along the web with the outer plate. The use of such a profile element is also interesting from an aesthetic point of view, since it opens the possibility to use different materials or different-looking surfaces on the outer plate and the profile element.
Um die Außenplatte und das Profilelement miteinander zu verbinden, kann ein Rand des Profilelements zu einem den Steg umgreifenden Haken geformt sein.In order to connect the outer panel and the profile element with each other, an edge of the profile element may be formed into a hook encompassing the web.
Umgekehrt ist auch der Fall denkbar, dass der Steg einteiliger Bestandteil des Profilelements ist. In einem solchen Fall kann ein Rand der Außenplatte zu einem den Steg umgreifenden Haken geformt sein, oder es können Ränder der Außenplatte und des Profilelements zu ineinander eingreifenden Haken umgebogen sein.Conversely, the case is also conceivable that the web is an integral part of the profile element. In such a case, an edge of the outer panel may be formed into a hook embracing the bridge, or edges of the outer panel and the profile member may be bent to interlocking hooks.
Wenn der Steg Teil einer von der Seitenflanke aus in die Tür eingetieften Rille ist, kann die Rille gleichzeitig die Funktion eines Griffs der Tür übernehmen.If the web is part of a groove recessed into the door from the side flank, the groove can simultaneously function as a handle of the door.
Eine solche Rille ist zweckmäßigerweise an einem Ende durch ein aufgestecktes Formteil verschlossen.Such a groove is expediently closed at one end by an attached molded part.
Um die Schaumdichtigkeit des Verschlusses zu gewährleisten, greifen Längsenden von Wänden der Griffrille vorzugsweise in eine Nut des Formteils ein.In order to ensure the foam-tightness of the closure, longitudinal ends of walls of the grip groove preferably engage in a groove of the molded part.
Ober- und Unterseite der Tür sind vorzugsweise jeweils durch ein Kopfstück verschlossen, das an einer Vorderseite eine Nut zum Aufnehmen eines von einem Rand der Außenplatte abgewinkelten Steges aufweist und mit dem Formteil durch Nut und Feder verbunden ist. Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Figuren. Es zeigen:The top and bottom of the door are preferably each closed by a head piece having a groove for receiving a angled from an edge of the outer plate web and is connected to the molding by tongue and groove on a front. Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

Fig 1 zeigt in perspektivischer Ansicht eine einteilig aus Blech geformte Außenplatte 1 einer Kältegerätetür. Die Außenplatte 1 umfasst eine Frontplatte 2, die die gesamte dem Benutzer zugewandte Vorderseite der Tür bildet, an die seitlichen Wände der Frontplatte 2 anschließende Seitenwangen 3, einen entlang des oberen Randes der Frontplatte nach hinten abgewinkelten schmalen Steg 4 und einen dem Steg 4 entsprechenden, nicht dargestellten Steg am unteren Rand der Frontplatte 2. Die Seitenwangen 3 umfassen eine Mehrzahl von jeweils in etwa rechtwinklig voneinander abgewinkelten Stegen, einem ersten äußeren Steg 5, der unmittelbar an die Frontplatte 2 angrenzt, Stege 6, 7, 8, die jeweils Seitenwände bzw. Boden einer in die Tür seitlich eingetieften Rille 9 bilden, sowie angrenzend an die Seitenwand 7 und bündig mit dem ersten äußeren Steg 5, einen zweiten äußeren Steg 10. Der äußere Steg 10 geht wiederum in einen zu der Frontplatte 2 parallelen Randsteg 11 über, an dem, wie in Fig. 2 gezeigt, eine Rückwandplatte 12 befestigt ist, die in herkömmlicher Weise aus Kunststoff tiefgezogen ist. Eine Verbindungszone, in der die Frontplatte 2 und die Rückwandplatte 12 aneinander grenzen, ist unter einer Magnetdichtung 13 verborgen.1 shows a perspective view of an integrally formed from sheet metal outer panel 1 of a refrigerator door. The outer panel 1 comprises a front panel 2 which forms the entire front of the door facing the user, side panels 3 adjoining the lateral walls of the front panel 2, a narrow bar 4 angled backwards along the upper edge of the front panel and a bar 4 corresponding to not illustrated web at the bottom of the front panel 2. The side walls 3 comprise a plurality of each approximately at right angles angled webs, a first outer web 5, which is directly adjacent to the front plate 2, webs 6, 7, 8, each side walls or bottom of a laterally recessed into the groove 9 groove, and adjacent to the side wall 7 and flush with the first outer web. 5 The outer web 10, in turn, merges into an edge web 11 parallel to the face plate 2, to which, as shown in FIG. 2, a back plate 12 is deep-drawn in a conventional plastic manner. A connection zone in which the front panel 2 and the rear wall panel 12 adjoin each other is hidden under a magnetic seal 13.
Die Rille 9 erstreckt sich in Breiten- und Tiefenrichtung der Tür jeweils über etwa ein bis zwei Zentimeter und über die gesamte Höhe der Tür. Die Rille 9 dient einerseits zur Versteifung der Seitenflanken der Tür, andererseits ist sie auch als Eingriff zum Öffnen der Tür nutzbar. Indem die Rille 9 auf beiden Seiten der Tür vorgesehen ist, ermöglicht sie eine Montage der Tür an einem Kältegerätegehäuse mit wahlweise rechtsseitigem oder linksseitigem Anschlag.The groove 9 extends in the width and depth direction of the door each about about one to two inches and over the entire height of the door. The groove 9 serves on the one hand to stiffen the side edges of the door, on the other hand, it is also used as an intervention to open the door. By the groove 9 is provided on both sides of the door, it allows mounting of the door to a refrigerator housing with either right-sided or left-sided stop.
Während die Außenplatte 1 sich in der Ausgestaltung der Fig. 1 und 2 über die gesamte Breite der Seitenflanken bis zur Rückwandplatte 12 erstreckt, bildet sie in der in Fig. 3 gezeigten Ausgestaltung nur einen vorderen äußeren Steg 5 der Seitenflanke und einen sich an den rückwärtigen Rand dieses Stegs 5 anschließenden Randsteg 20, der ins Innere der Tür und zurück nach vorn umgebogen ist, um einen sich über die gesamte Höhe der Tür erstreckenden Haken 14 zu bilden. In den Haken 14 greift ein komplementärer Haken 15 eines Profilelements 16 ein. Das Profilelement 16 bildet eine Rille 9, einen zweiten äußeren Steg 10 und den mit der Rückwandplatte 12 verbundenen Randsteg 1 1.While the outer plate 1 extends in the embodiment of FIGS. 1 and 2 over the entire width of the side edges to the rear wall plate 12, it forms in the embodiment shown in Fig. 3, only a front outer web 5 of the side edge and one at the rear Edge of this web 5 adjoining edge web 20, which is bent into the interior of the door and back forward to form over the entire height of the door extending hook 14. In the hook 14 engages a complementary hook 15 of a profile element 16 a. The profile element 16 forms a groove 9, a second outer web 10 and connected to the rear wall plate 12 edge web 1 first
Hier ist es in erster Linie das Profilelement 16, welches durch die Rille 9 eine hohe Biegesteifigkeit erhält. Durch die ineinander greifenden Haken 14, 15 stabilisiert es aber auch den zur Frontplatte gehörenden vorderen äußeren Steg 5 gegen eine mögliche Verformung beim Ausschäumen.Here it is primarily the profile element 16, which receives a high bending stiffness through the groove 9. By the interlocking hooks 14, 15 but it also stabilizes the belonging to the front panel front outer web 5 against a possible deformation during foaming.
Der zweiteilige Aufbau der Seitenflanken der Tür gemäß dieser Ausgestaltung schafft die Möglichkeit, unterschiedliche Materialien oder Oberflächen an der Außenplatte 1 und den sie beiderseits einfassenden Profilelementen 16 zu verwenden. So ergeben sich neuartige Gestaltungsmöglichkeiten zum Beispiel durch Verwendung von blankem Metall, insbesondere Aluminium oder Edelstahl für die Außenplatte 1 und gefärbtem Kunststoff oder lackiertem Metall für die Profilelemente 16.The two-part construction of the side flanks of the door according to this embodiment makes it possible to use different materials or surfaces on the outer panel 1 and the profiled elements 16 enclosing them on both sides. So arise novel design options, for example by using bare metal, in particular aluminum or stainless steel for the outer panel 1 and colored plastic or painted metal for the profile elements 16th
Ein weiterer Vorteil der Ausgestaltung der Fig. 3 ist, dass die Außenplatte 1 mit Profilelementen 16 unterschiedlicher Querschnitte kombinierbar ist. So zeigt Fig. 4 die gleiche Außenplatte wie Fig. 3 kombiniert mit einem Profilelement 16, bei dem die Rille 9 fehlt. Zwar entfällt so auch die Versteifungswirkung der Rille, doch kommt eineAnother advantage of the embodiment of FIG. 3 is that the outer panel 1 can be combined with profile elements 16 of different cross sections. Thus, Fig. 4 shows the same outer panel as Fig. 3 combined with a profile element 16, in which the groove 9 is missing. Although it eliminates the stiffening effect of the groove, but comes one
Versteifung auch durch die sich überlappenden Stege der ineinander greifenden HakenStiffening also by the overlapping webs of interlocking hooks
14, 15 zustande, die zumindest auf einem Teil der Seitenflanke vier Materialschichten nebeneinander bilden.14, 15, which form at least on one side of the side edge four layers of material next to each other.
Ein Türgriff 17 ist bei dieser Ausgestaltung zweckmäßigerweise an dem Profilelement 16 montiert; die Außenplatte 1 kann dann mit derjenigen der Ausgestaltung von Fig. 3 exakt identisch sein.A door handle 17 is expediently mounted on the profile element 16 in this embodiment; The outer panel 1 can then be exactly identical to that of the embodiment of FIG. 3.
Eine weitere Variante mit verbesserter Versteifungswirkung ist in Fig. 5 gezeigt. Hier ist ein Rand der Außenplatte 1 nicht wie in Fig. 3 und 4 nach innen und nach vorn zurückgeschlagen, um den Haken 14 zu bilden, sondern lediglich etwa rechtwinklig ins Innere der Tür hinein abgewinkelt, so dass ein zur Vorderseite der Tür in etwa paralleler Steg 18 erhalten wird. Ein Haken 19 des Profilelements 16 umgreift den Steg 18. Steg 18 und Haken 19 sind durch Punktschweißungen aneinander befestigt. Die Punktschweißungen sind bequem mit einer an den Außenseiten des Hakens 19 angreifenden Schweißzange erzeugbar; an dem Haken 19 zurückbleibende Schweißmale sind an der fertigen Tür nicht sichtbar, da sie in ihrem Inneren verborgen bleiben.Another variant with improved stiffening effect is shown in FIG. Here, an edge of the outer panel 1 is not as shown in Figs. 3 and 4 turned back inwardly and forward to form the hook 14, but only approximately at right angles into the interior of the door angled so that one to the front of the door in approximately parallel Bridge 18 is obtained. A hook 19 of the profile element 16 surrounds the web 18. The web 18 and hooks 19 are fastened to each other by spot welds. The spot welds are conveniently produced with a welding tongs acting on the outer sides of the hook 19; Weld marks remaining on the hook 19 are not visible on the finished door as they remain hidden inside.
Die Fertigung der Außenplatte 1 gemäß Fig. 5 unterscheidet sich von der gemäß Fig. 3 lediglich durch den Winkel, um den der seitliche Rand der Außenplatte umgebogen wird, um entweder den Haken 14 oder den Steg 18 zu bilden. Dieser geringe Unterschied schließt eine Fertigung der zwei Typen von Außenplatten 1 unter Verwendung weitgehend gleicher Werkzeuge nicht aus, so dass auch hier eine rationelle Fertigung unterschiedlicher Typen von Kältegerätetüren möglich ist. Selbstverständlich könnte umgekehrt zur Darstellung der Fig. 5 auch das Profilelement 16 mit einem einfachen, parallel zur Frontseite ins Innere der Tür hinein eingreifenden Steg und die Außenplatte mit einem diesen Steg umgreifenden Haken versehen sein.The manufacture of the outer panel 1 of FIG. 5 differs from that of FIG. 3 only by the angle by which the lateral edge of the outer panel is bent to form either the hook 14 or the web 18. This small difference does not exclude a production of the two types of outer panels 1 using largely the same tools, so that here too a rational production of different types of refrigerator doors is possible. Of course, conversely to the representation of FIG. 5, the profile element 16 could be provided with a simple, parallel to the front inside the door engaging web and the outer plate with a web embracing this hook.
Fig. 6 zeigt in einer perspektivischen Ansicht eine Endkappe 21 , die in den Ausgestaltungen der Fig. 1 und 2 oder 3 vorgesehen ist, um die Rille 9 an ihrem oberen und unteren Ende dicht zu verschließen und ein Ausschäumen der Tür möglich zu machen. Eine flache Mulde 22 an der Unterseite der Endkappe 21 bildet den Abschluss der Rille 9.
