Description

Tür für ein Kältegerät Door for a refrigeration appliance
Die vorliegende Erfindung betrifft eine Tür für ein Kältegerät, die zur Montage von Türabstellern an ihrer Innenseite geeignet ist.The present invention relates to a door for a refrigerator, which is suitable for mounting door housings on its inside.
Herkömmlicherweise ist die Tür eines Kältegeräts zusammengefügt aus einer festen Außenwand und einer Innenwand, die durch Tiefziehen aus einer Kunststoffplatine geformt ist, und ein Zwischenraum zwischen Außen- und Innenwand ist mit einem Polymermaterial ausgeschäumt, das zur thermischen Isolation dient. An der Innenwand sind vertikale Holme einteilig ausgeformt, die an einander zugewandten Seitenflächen Vorsprünge aufweisen, auf die ein Türabsteller aufgehängt werden kann.Conventionally, the door of a refrigerator is composed of a solid outer wall and an inner wall which is formed by deep drawing of a plastic board, and a gap between the outer and inner walls is foamed with a polymer material, which serves for thermal insulation. On the inner wall vertical bars are integrally formed, which have projections on mutually facing side surfaces on which a door rack can be suspended.
Die Fertigungsweise der Türinnenwand durch Tiefziehen bringt es mit sich, dass die Wandstärke der Holme, in denen das Kunststoffmaterial stärker gedehnt ist, als in umgebenden, im wesentlichen ebenen Bereichen der Türinnenwand, dünner sind als diese benachbarten Bereiche, und die aus den Flanken der Holme ausgeformten Vorsprünge sind wiederum dünnwandiger als der Rest des Holms. Es ist daher eine erhebliche Materialstärke der Innenwand erforderlich, um eine ausreichende Belastbarkeit der die Türabsteller tragenden Vorsprünge zu gewährleisten. Insbesondere bei weit über die Holme vorspringenden Türabstellern wirkt auf die Vorsprünge nicht nur das Gewicht der Türabsteller und der darauf befindlichen Gegenstände, sondern es können darüber hinaus erhebliche Kräfte durch Hebelwirkung auftreten, die die Vorsprünge erheblich belasten.The way in which the inner wall of the door is made by deep-drawing entails that the wall thickness of the spars, in which the plastic material is stretched more extensively than in surrounding, essentially flat areas of the inner wall of the door, is thinner than these adjacent areas, and that of the flanks of the spars formed projections are again thinner wall than the rest of the spar. It is therefore a considerable thickness of the inner wall required to ensure sufficient load capacity of the door rests bearing projections. In particular, in far above the spars projecting door compartments acts on the projections not only the weight of the door racks and the objects located thereon, but it can also considerable forces occur by leverage, which significantly burden the projections.
Es besteht daher Bedarf nach einer Tür für ein Kältegerät, die eine sichere und belastbare Aufhängung von Türabstellern ermöglicht, die ein hohes Gewicht haben und/oder weit von der Innenwand der Tür abstehen.There is therefore a need for a door for a refrigerator, which allows a safe and resilient suspension of door cabinets, which have a high weight and / or protrude far from the inner wall of the door.
Die Aufgabe wird dadurch gelöst, dass bei einer Tür für ein Kältegerät mit einer Innenwand und einer Außenwand, die einen Zwischenraum umgeben, und mit von der Innenwand abstehenden vertikalen Holmen, die Raststufen für Türabsteller aufweisen, die Holme wenigstens teilweise durch ein vertikales Profilteil gebildet sind und die Raststufen an dem Profilteil gebildet sind. Da das Profilteil, insbesondere wenn es sich über mehrere Raststufen erstreckt, eine erhebliche vertikale Ausdehnung haben kann, sind horizontale Kraftkomponenten, die von dem Profilteil in die Türinnenwand einzuleiten sind, im Vergleich zum Fall der herkömmlichen direkten Aufhängung der Türabsteller an den aus der Innenwand ausgeformten Vorsprüngen gering, und das Problem der auf der Hebelwirkung beruhenden horizontalen Kräfte tritt im wesentlichen nur an den Raststufen des Profilteils selber auf. Da das Profilteil jedoch ein von der Türinnenwand getrenntes Bauteil ist, kann es problemlos mit der erforderlichen Wandstärke und Festigkeit ausgelegt werden, ohne dass gleichzeitig die gesamte Innenwand dicker gemacht werden müsste, als für deren ebene Bereiche erforderlich ist.The object is achieved in that, in a door for a refrigeration device having an inner wall and an outer wall, which surround a gap, and projecting from the inner wall vertical bars, the latching stages for door racks, the spars are at least partially formed by a vertical profile part and the latching steps are formed on the profile part. Since the profile part, in particular when it extends over a plurality of latching steps, may have a considerable vertical extent, are horizontal force components to be initiated by the profile part in the door inner wall, compared to the case of the conventional direct suspension of the door racks on the formed from the inner wall Projections small, and the problem of the leverage based horizontal forces occurs essentially only at the latching steps of the profile part itself. However, since the profile part is a separate component from the door inner wall, it can be easily designed with the required wall thickness and strength, without at the same time the entire inner wall would have to be made thicker than is required for the flat areas.
Vorzugsweise ist das Profilteil ein Strangprofil aus einem Metall, insbesondere Aluminium oder rostfreiem Stahl.Preferably, the profile part is an extruded profile of a metal, in particular aluminum or stainless steel.
Aus ästhetischen Gründen und im Interesse einer einfachen Sauberhaltung sollte das Profilteil an seinen Enden verschlossen sein. Dies kann einfach und ansprechend mit einem aus der Innenwand ausgeformten Vorsprung erfolgen.For aesthetic reasons and in the interests of easy keeping clean the profile part should be closed at its ends. This can be done easily and responsively with a molded-out of the inner wall projection.
Das Profilteil ist an der Innenwand vorzugsweise mit Hilfe von Schrauben befestigt.The profile part is preferably fixed to the inner wall by means of screws.
Bei einem Profilteil mit einer an der Innenwand der Tür anliegenden Rückwand und einer Außenwand, in der die Raststufen in Form von Öffnungen gebildet sind, können die Schrauben vorteilhaft so eingesetzt sein, dass sie die Rückwand durchsetzen und durch die Öffnungen der Außenwand hindurch zugänglich sind, um sie zu lösen oder festzuziehen. Das Profilteil ist so bequem an- oder abmontierbar, aber die zu seiner Befestigung verwendeten Schrauben sind versteckt, sobald die Öffnungen der Raststufen durch an ihnen aufgehängte Türabsteller verdeckt sind.In a profile part with a voltage applied to the inner wall of the door rear wall and an outer wall in which the latching steps are formed in the form of openings, the screws can be advantageously used so that they pass through the rear wall and are accessible through the openings of the outer wall, to loosen or tighten. The profile part is so easy to assemble or disassemble, but the screws used for its attachment are hidden as soon as the openings of the locking steps are concealed by suspended on them door racks.
Um die Anbringung der Schrauben zu vereinfachen, ist die Rückwand des Profilteils vorzugsweise schräg in Bezug auf eine Hauptoberfläche der Tür ausgerichtet, so dass die durch die Öffnung einer Raststufe eingeführte Schraube in ungefähr senkrechter Richtung auf die Rückwand trifft. Um einen festen Halt der Schrauben zu gewährleisten, stehen diese vorzugsweise mit einem in dem Zwischenraum der Tür aufgenommenen Hinterlegteil in Gewindeeingriff. Dieses Hinterlegteil, das zweckmäßigerweise ebenfalls aus Metall bestehen kann, verringert die Anforderungen an die Stärke der Innenwand weiter.To facilitate the attachment of the screws, the rear wall of the profile part is preferably aligned obliquely with respect to a main surface of the door, so that the screw inserted through the opening of a latching step meets the rear wall in an approximately perpendicular direction. In order to ensure a firm grip of the screws, these are preferably in threaded engagement with a locking member received in the space of the door. This backing part, which may conveniently also be made of metal, further reduces the requirements for the thickness of the inner wall.
Mit Hilfe von Flügeln, die iin den Zwischenraum hinein abstehen und in eine den Zwischenraum ausfüllende Isolationsmaterialschicht eingebettet sind, ist das Hinterlegteil nicht nur an der Innenwand der Tür abgestützt, sondern auch in der Isolationsmaterialschicht verankert.With the help of wings which project into the gap and are embedded in an insulating material layer filling the gap, the backing piece is not only supported on the inner wall of the door, but also anchored in the insulation material layer.

Fig. 1 ist perspektivische Ansicht einer mit Türabstellern 2, 3 bestückten Kältegerätetür 1. Die Kältegerätetür 1 ist in an sich bekannter Weise zusammengesetzt aus einer in der Fig. vom Betrachter abgewandten Außenwand und einer Innenwand 4 aus Kunststoff, die verborgen hinter einer umlaufenden Magnetdichtung 5 miteinander schaumdicht verbunden sind, um einen mit einem expandierten Polymermaterial als Isolationsmaterial ausgefüllten Zwischenraum zu begrenzen.1 is a perspective view of a refrigerated appliance door 1 equipped with door compartments 2, 3. The refrigerator door 1 is composed in a manner known per se of an outer wall facing away from the observer in the figure and an inner wall 4 made of plastic, which is hidden behind a circulating magnetic seal 5 are foam-tight connected to each other to limit a space filled with an expanded polymer material as insulation material gap.
An der Innenwand 4 erstrecken sich benachbart zu deren seitlichen Kanten zwei vertikale Holme 6, an denen die Türabsteller 2, 3 aufgehängt sind. Die Holme 6 haben jeweils einen oberen und einen unteren Endabschnitt 8, 9, in dem sie in herkömmlicher Weise auf ihrer gesamten Tiefe einteilig aus der Platte der Innenwand 4 tiefgezogen sind. Zwischen den Endabschnitten 8, 9 sind die Holme 6 nur auf einem Teil ihrer Tiefe aus der Innenwand 4 tiefgezogen, und die daraus zwischen den Endabschnitten 8, 9 resultierenden Aussparungen der Holme 6 sind jeweils mit einem Strangprofil 7 aus Aluminium allseits bündig ausgefüllt. In dem Strangprofil 7 sind in der Fig. nicht sichtbare Raststufen gebildet, an denen die Türabsteller 2, 3 befestigt sind.On the inner wall 4 extend adjacent to the lateral edges of two vertical bars 6, where the door racks 2, 3 are suspended. The spars 6 have each an upper and a lower end portion 8, 9, in which they are deep drawn in a conventional manner over its entire depth in one piece from the plate of the inner wall 4. Between the end portions 8, 9, the spars 6 are deep-drawn only on part of their depth from the inner wall 4, and the resulting between the end portions 8, 9 recesses of the spars 6 are each filled with an extruded profile 7 made of aluminum on all sides. In the extruded profile 7 not visible locking steps are formed in the figure, where the door racks 2, 3 are attached.
Fig. 2 ist eine perspektivische Ansicht des oberen Bereichs der Kältegerätetür 1 ohne die Türabsteller. Wie man hier sieht, erstreckt sich das Strangprofil 7 an den voneinander abgewandten Außenseiten 10 der Holme 6 etwa über die Hälfte von deren Tiefe, während die einander zugewandten Seitenflächen 11 zwischen den Endabschnitten 8, 9 vollständig von dem Strangprofil 7 ausgefüllt sind. Eine Raststufe 12 für einen Türabsteller ist gebildet durch eine in das Strangprofil 7 gefräste Öffnung, die sich über einen Teil einer Scheitelfläche 13 des Strangprofils 7 und winkelförmig auf der Seitenfläche 11 erstreckt.Fig. 2 is a perspective view of the upper portion of the refrigerator door 1 without the door racks. As can be seen here, the extruded profile 7 extends on the outer sides 10 of the uprights 6 facing away from each other approximately over half their depth, while the mutually facing side surfaces 11 between the end sections 8, 9 are completely filled by the extruded profile 7. A latching step 12 for a door racks is formed by an opening machined into the extruded profile 7, which extends over a part of a vertex surface 13 of the extruded profile 7 and angularly on the side surface 11.
Fig. zeigt den zur Montage an den Raststufen 12 vorgesehenen Türabsteller 2, gesehen von seiner im montierten Zustand der Tür 1 zugewandten Rückseite. Der dargestellte Türabsteller 2 ist als Butterfach ausgebildet, mit einer schwenkbaren Klappe 14, die eine Oberseite und eine dem Innern eines Kältegeräts, an dem die Tür 1 montiert ist, zugewandte Frontseite des Türabstellers 2 bildet, einer Rückseite 15, einem Boden und Stirnseiten 16. Die Stirnseiten 16 sind durch eine Stufe 17 in einen frei sichtbaren Bereich und einen im montierten Zustand an der Seitenfläche 1 eines Strangprofils 7 anliegenden zurückversetzten Bereich 18 unterteilt. Von dem Bereich 18 steht ein Zapfen 19 ab, der vorgesehen ist, um in die Raststufe 12 des Strangprofils 7 eingehängt zu werden.Fig. Shows the intended for mounting on the locking steps 12 door rack 2, seen from its in the mounted state of the door 1 facing the rear. The illustrated door rack 2 is designed as a butter compartment, with a pivotable flap 14 which forms an upper side and a front side of the door compartment 2 facing the interior of a refrigeration device on which the door 1 is mounted, a rear side 15, a bottom and front sides 16. The end faces 16 are subdivided by a step 17 into a freely visible area and a recessed area 18 in the mounted state on the side face 1 of an extruded profile 7. From the area 18 is a pin 19, which is intended to be hooked into the latching step 12 of the extruded profile 7.
Fig. 4 ist eine zweite perspektivische Ansicht des oberen Bereichs der Kältegerätetür 1, diesmal mit weggelassenen Strangprofilen 7. Wie man sieht, verdecken diese zwischen den Endabschnitten 8, 9 eine einteilig aus der Innenwand 4 ausgeformte Rippe 20 von in etwa dreieckigem Querschnitt, wobei voneinander abgewandte Flanken der zwei Rippen jeweils einen Teil der Seitenflanken 10 bilden und einander zugewandte Flanken 20, die jeweils einen stumpfen Winkel mit einer dazwischenliegenden zentralen Planfläche 22 der Innenwand 4 bilden, im fertig montierten Zustand von den Strangprofilen 7 verdeckt sind. An den Flanken 21 sind mehrere Schraublöcher 23 zu sehen. Fig. 5 zeigt einen horizontalen Teilschnitt durch die Tür 1 und einen daran aufgehängten Türabsteller 2 in Höhe von dessen Zapfen 19. Wie man hier sieht, ist das Strangprofil 7 ein Hohlprofil mit mehreren inneren Kammern 24 und einer an der Flanke 21 anliegenden Rückwand 25. Die Rückwand 25 und die Flanke 21 sind jeweils in Höhe jeder Raststufe 12 von einer Schraube 26 durchsetzt, deren in der Fig. nicht sichtbarer, an der Rückwand 25 anliegender Kopf die Rückwand 25 gegen die Flanke 21 presst. Die Schraube 26 ist verankert in einem Hinterlegteil 27 aus Blech, das hier in etwa die Form eines U-Profils mit einem an der Innenseite der Flanke anliegenden Mittelabschnitt 28 und zwei von dem Mittelabschnitt 28 in den mit in der Fig. nicht gezeigtem Isoliermaterial ausgefüllten Zwischenraum zwischen der Innenwand 4 und Außenwand 29 der Tür eingreifenden Schenkeln 30 hat. Das Hinterlegteil 23 erstreckt sich vertikal über die gesamte Länge des Strangprofils 7. Die Schenkel 30 haben auseinanderlaufende Endabschnitte 31 , die es erlauben, eine von der Schraube 26 ausgeübte horizontale Zugkraft in das Isoliermaterial großflächig einzuleiten. So wird auch das Isoliermaterial zur Halterung der Türabsteller 2, 3 genutzt, so dass die Stärke der Innenwand 4 besonders gering gemacht werden kann.4 is a second perspective view of the upper portion of refrigerator door 1, this time with extruded sections 7. As can be seen, these cover, between end portions 8, 9, a rib 20 formed integrally with inner wall 4, of approximately triangular cross-section, from each other opposite flanks of the two ribs each form a part of the side edges 10 and facing flanks 20, each forming an obtuse angle with an intermediate central plane surface 22 of the inner wall 4, are covered in the assembled state of the extruded profiles 7. On the flanks 21 a plurality of screw holes 23 can be seen. 5 shows a horizontal partial section through the door 1 and a door rack 2 suspended therefrom at the level of its pin 19. As can be seen, the extruded profile 7 is a hollow profile with a plurality of inner chambers 24 and a rear wall 25 resting against the flank 21. The rear wall 25 and the edge 21 are each penetrated at the level of each latching stage 12 by a screw 26 whose not visible in the Fig, on the rear wall 25 abutting head presses the rear wall 25 against the edge 21. The screw 26 is anchored in a backing piece 27 made of sheet metal, here approximately in the form of a U-profile with a voltage applied to the inside of the flank central portion 28 and two of the central portion 28 in the filled with not shown in the insulating material space between the inner wall 4 and outer wall 29 of the door engaging legs 30 has. The backing piece 23 extends vertically over the entire length of the extruded profile 7. The legs 30 have diverging end portions 31, which allow a large horizontal force exerted by the screw 26 horizontal tensile force in the insulating material. Thus, the insulating material for holding the door racks 2, 3 is used, so that the strength of the inner wall 4 can be made very low.
Ein Teil der äußeren Seitenfläche 10 jedes Holms 6 ist durch einen kurzen Steg 32 gebildet, der von dem Strangprofil 7 aus über die an der Flanke 21 anliegende RückwandA portion of the outer side surface 10 of each spar 6 is formed by a short web 32 which extends from the extruded profile 7 via the abutting against the flank 21 rear wall
