Description

Die vorliegende Erfindung betrifft ein Kältegerät mit einer an seinem wärmeisolierenden Gehäuse angeschlagenen Tür, einem an der Tür um eine Achse drehbar gelagerten, als zweiarmiger Hebel ausgebildeten Türgriff, und einem Führungselement, das eine zu der Achse konzentrische Führungsschiene trägt, die in eine in dem Türgriff gebildete Gegenführungsschiene eingreift. Ein solches Kältegerät mit den Merkmalen des Oberbegriffs des Anspruchs 1 ist aus EP 0 891524 B1 bekannt.The present invention relates to a refrigerator having a door hinged to its heat-insulating housing, a door handle rotatably mounted about an axis, designed as a two-armed lever door handle, and a guide member which carries a concentric to the axis guide rail, which in one in the door handle formed counter-guide rail engages. Such a refrigerator with the features of the preamble of claim 1 is made EP 0 891524 B1 known.

Bei Kältegeräten, insbesondere solchen mit großflächigen Türen, werden zunehmend Türöffnungshilfen eingebaut, die einem Benutzer das Öffnen der Tür entgegen einer Schließkraft erleichtern, die z.B. durch magnetische Anziehungskraft einer Magnetdichtung oder einen in dem Gerät herrschenden Unterdruck erzeugt sein kann. Insbesondere ein solcher Unterdruck, der entsteht, wenn nach dem Türöffnen ins Innere des Gerätes eingedrungene Luft sich abkühlt, kann eine erhebliche Schließkraft hervorrufen, so dass, wenn ein Benutzer zum Überwinden der Schließkraft an der Tür zieht, unter Umständen die Standfestigkeit des Kältegeräts beeinträchtigt sein kann. Bei dem aus EP 0 891 524 B1 bekannten Kältegerät ist als Türöffnungshilfe ein Türgriff verwendet, der, anstatt starr an der Tür befestigt zu sein, mit dieser um eine Achse drehbar verbunden ist und aus zwei von der Achse ausgehenden Hebelarmen aufgebaut ist, einem längeren, der als Handgriff zum Öffnen der Tür dient, und einem kürzeren, der sich beim Betätigen des Handgriffs am Gehäuse abstützt und so die Tür vom Gehäuse abspreizt.In refrigerators, especially those with large doors, door opening aids are increasingly installed, which facilitate a user opening the door against a closing force, which may be generated for example by magnetic attraction of a magnetic seal or a pressure prevailing in the device vacuum. In particular, such a negative pressure, which occurs when air which has penetrated into the interior of the device after the door has opened, can produce a considerable closing force, so that if a user pulls on the door to overcome the closing force, the stability of the refrigeration device may be impaired can. At the EP 0 891 524 B1 Known refrigeration device is used as a door opening aid, a door handle which, instead of being rigidly attached to the door, is rotatably connected to this about an axis and constructed of two outgoing from the axis of the lever arms, a longer, which serves as a handle for opening the door , and a shorter, which is supported when operating the handle on the housing and thus spreads the door from the housing.

Ein Problem bei einer derartigen Türöffnungshilfe ist, dass zwischen der Achse und dem Türgriff ein gewisses Spiel vorhanden sein muss, damit der Türgriff frei schwenkbar ist, die Achse aber im allgemeinen recht kurz ist und die Drehung des Türgriffs um die Achse infolgedessen nur mit geringer Stabilität zu führen vermag. Diese geringe Stabilität kann bei einem Benutzer den Eindruck mangelnder Haltbarkeit und Qualität d es K ältegeräts hervorrufen, was zu vermeiden ist.A problem with such a door opening aid is that there must be some play between the axle and the door handle so that the door handle is free to pivot, but the axis is generally quite short and the rotation of the door handle about the axle is consequently of only limited stability to lead. This low stability can give a user the impression of lack of durability and quality of the refrigerator, which should be avoided.

Zur Stabilisierung der Schwenkbewegung wird daher bei EP 0 891 524 B1 eine zu der Achse konzentrische Führungsschiene eingesetzt, die in eine an dem Griff gebildete, als Gegenführung ausgeführte Gegenführungsschiene eingreift.To stabilize the pivoting movement is therefore at EP 0 891 524 B1 a concentric with the axis guide rail used, which engages in a counter-guide rail formed on the handle, designed as a counter-guide.

Diese bekannte Führungsschiene ist ausgebildet als gekröpfter Rand einer Metallplatte, die an einer seitlichen Flanke der Tür befestigt ist. Der gekröpfte Rand steht von der Tür in seitlicher Richtung ab und ist überdeckt von dem Türgriff. Dieser weist somit einen erheblichen seitlichen Überstand über die Tür auf, er reicht sogar über die Fluchtlinie der Seitenwand des Gehäuses hinaus. Dieser seitliche Überstand macht es unmöglich, das bekannte Kühlgerät in unmittelbarem seitlichen Kontakt mit einem zweiten Gerät aufzustellen.This known guide rail is formed as a cranked edge of a metal plate which is fixed to a side edge of the door. The bent edge protrudes from the door in a lateral direction and is covered by the door handle. This thus has a considerable lateral projection over the door, it even extends beyond the line of flight of the side wall of the housing. This lateral projection makes it impossible to set up the known cooling device in direct lateral contact with a second device.

Dieses Problem könnte zwar prinzipiell behoben werden, indem die Tür des Kältegeräts schmaler gemacht wird; dann müßte jedoch auch die an der Tür angebrachte Magnetdichtung nach innen verlagert werden, und die Kontaktfläche für die Magnetdichtung an der Vorderseite des Gerätegehäuses müßte verbreitert werden, um weiterhin einen dicht schließenden Kontakt zwischen Magnetdichtung und Gehäuse zu ermöglichen. Dies würde nicht nur Konstruktionsänderungen am Kältegerätegehäuse erfordern, zusätzlich ginge auch Stauvolumen in dessen Innerem verloren.Although this problem could be remedied in principle by the door of the refrigerator is made narrower; then, however, the attached to the door magnetic seal would have to be displaced inward, and the contact surface for the magnetic seal on the front of the device housing would have to be broadened to further allow a tight-fitting contact between the magnetic seal and the housing. This would not only require design changes to the refrigerator housing, in addition, storage volume would be lost in the interior.

Aufgabe der vorliegenden Erfindung ist daher, ein Kältegerät mit einem als Türöffnungshilfe fungierenden Türgriff zu schaffen, bei dem der seitliche Überstand des Türgriffs über die Tür reduziert ist, und zwar vorzugsweise soweit, dass mehrere derartige Kältegeräte in Kontakt nebeneinander aufgestellt werden können, ohne dass der Türgriff des einen an die Tür oder einen Türgriff eines benachbarten Geräts anstößt.Object of the present invention is therefore to provide a refrigeration device with a door handle acting as a door handle, wherein the lateral projection of the door handle is reduced via the door, and preferably so far that several such refrigerators can be placed in contact next to each other without the Door handle of one to the door or a door handle of a neighboring device abuts.

Die Aufgabe wird gelöst durch ein Kältegerät mit den Merkmalen des Anspruchs 1.The object is achieved by a refrigeration device having the features of claim 1.

Da bei dem bekannten Kältegerät die Führungsschiene jeweils der Seitenwange der Tür gegenüberliegend angeordnet ist, ist eine Kröpfung und damit ein seitlicher Abstand der Führungsschiene von der Seitenwange der Tür erforderlich, um die Führungsschiene mit der Gegenführungsschiene beiderseits umgreifen zu können. Indem erfindungsgemäß die Führungsschiene auf einen über die Seitenwange der Tür überstehenden Bereich des Führungselements verlagert ist, ist eine solche Kröpfung überflüssig, und der seitliche Überstand des Türgriffs über die Tür kann ohne Verlust an Stabilität für die Führung und die Befestigung des Türgriffs um die Stärke der Kröpfung verringert werden. Vorzugsweise ist das Führungselement beim erfindungsgemäßen Kältegerät einfach als eine ebene Platte ausgebildet. Dadurch, dass das Führungselement als ebene Platte ausgebildet ist, ist deren Herstellung deutlich vereinfacht und somit sehr kostengünstig. Diese Platte ist vorzugsweise kreissegmentförmig, wobei zweckmäßigerweise wenigstens ein mittlerer Abschnitt des gekrümmten Randes dieser Platte die Führungsschiene bildet.Since in the known refrigeration device, the guide rail in each case the side cheek of the door is arranged opposite, a cranking and thus a lateral distance of the guide rail of the side cheek of the door is required in order to engage around the guide rail with the counter guide rail on both sides. By the present invention, the guide rail is displaced to a projecting beyond the side wall of the door portion of the guide element, such a crank is superfluous, and the lateral projection of the door handle on the door without loss of stability for the leadership and attachment of the door handle to the strength of Crease be reduced. Preferably, the guide element in the refrigerator according to the invention is simply designed as a flat plate. The fact that the guide element is formed as a flat plate, their production is much easier and thus very inexpensive. This plate is preferably circular segment-shaped, wherein expediently at least one middle section of the curved edge of this plate forms the guide rail.

Es ist vorgesehen, dass der die Führungsschiene aufweisende überstehende Bereich von der Tür nach vorn absteht, d.h. über die Seitenflanke in tangentialer Richtung vom Gehäuse des Kältegeräts fort übersteht.It is envisaged that the projecting portion having the guide rail projecting forward from the door, i. protrudes beyond the side edge in tangential direction away from the housing of the refrigerator.

Um die Schwenkbewegung des Türgriffs wirksam zu stabilisieren, ist es wünschenswert, dass sich die Gegenführungsschiene über einen möglichst großen Winkel erstreckt; vorzugsweise sollten die Enden der Gegenführungsschiene in Bezug auf die Achse einen Winkel von wenigstens 120 aufspannen. Gleichzeitig wird die auf den Türgriff ausgeübte Betätigungskraft verhältnismäßig großflächig und somit sehr vergleichmäßigt über das Führungselement in der Tür eingeleitet.In order to effectively stabilize the pivotal movement of the door handle, it is desirable that the counter-guide rail extend over as large an angle as possible; Preferably, the ends of the counter guide rail should span at an angle of at least 120 with respect to the axle. At the same time, the force exerted on the door handle operating force is introduced relatively large area and thus very evenly over the guide element in the door.

Andererseits darf der aufgespannte Winkel nicht zu groß sein, damit die Enden der Gegenführungsschiene nicht durch Anstoßen an die Tür die gewünschte Schwenkbewegungsfreiheit des Türgriffs über Gebühr beeinträchtigen. Unter diesem Gesichtspunkt ist bevorzugt, dass die Enden der Gegenführungsschiene an der Achse einen Winkel von höchstens 130 ° aufspannen.On the other hand, the clamped angle must not be too large, so that the ends of the counter guide rail do not interfere with the desired pivoting freedom of the door handle overpowered by abutting the door. From this point of view, it is preferable that the ends of the counter guide rail subtend an angle of at most 130 ° to the axle.

Fig. 1 zeigt als Beispiel für ein erfindungsgemäßes Kältegerät einen Haushalts-Gefrierschrank 10, dessen wärmeisolierend ausgebildetes Gehäuse 11 einen Gefrierraum 12 aufweist, welcher zur Aufnahme von übereinander angeordneten, schubladenartig ausgebildeten Gefriergutbehältern 13 dient und welcher über eine Zugangsöffnung am Gehäuse 11 zugänglich ist. Die Zugangsöffnung ist von einer am Gehäuse 11 angeschlagenen Tür 14 abdeckbar, welche im abgedeckten Zustand über eine Magnetdichtung 15 elastisch am Rand der Zugangsöffnung aufliegt. Zum Öffnen der Tür 14 ist an ihrer der Anschlagsseite gegenüberliegenden Seitenwange 16 ein daran drehbar gelagerter Türgriff 20 vorgesehen. Wie insbesondere aus Fig. 2 hervorgeht, ist der Türgriff 20 als ein um eine Drehachse 23 drehbar gelagerter zweiarmiger Hebel ausgebildet, dessen Hebelarme 21, 22 eine unterschiedliche Hebellänge 11 und 12 aufweisen, wobei der Hebelarm 22 die kürzere Hebellänge 12 aufweist. Fig. 1 shows as an example of a refrigerator according to the invention a household freezer 10, the heat-insulating housing 11 has a freezer compartment 12 which serves to receive stacked, designed like a drawer-shaped Gefgutbehältern 13 and which is accessible via an access opening on the housing 11. The access opening can be covered by a door 14 hinged to the housing 11, which in the covered state rests elastically on the edge of the access opening via a magnetic seal 15. To open the door 14, a door handle 20 rotatably mounted thereon is provided on its side wall 16 opposite the abutment side. As in particular from Fig. 2 As can be seen, the door handle 20 is formed as a two-axis lever rotatably mounted about a rotation axis 23, the lever arms 21, 22 have a different lever length 11 and 12, wherein the lever arm 22 has the shorter lever length 12.

Der Türgriff 20 ist aufgebaut aus einem rohrförmigen Abschnitt 24 und einem auf einem Teil der Länge des rohrförmigen Abschnitts 24 an diesen anschließenden Abschnitt in Form eines Winkelprofils 25, wie gezeigt in Fig. 2. Ein an den Abschnitt 24 angrenzender Schenkel 26 des Winkelprofils 25 erstreckt sich in etwa parallel zur Vorderseite der Tür 14; der mit dem Schenkel 26 über eine Rundung verbundene zweite Schenkel 27 liegt an der Seitenwange 16 der Tür drehbar an. In der in Fig. 2 mit durchgezogenen Linien dargestellten Stellung des Türgriffs 20 liegt ein Puffer 28, der den Abschluß des Hebelarms 22 bildet, am vorderen Rand des Gehäuses 11 an. Wenn ein Benutzer am Hebelarm 22 zieht, drückt der Puffer 28 gegen diese Vorderkante und spreizt die Tür 14 vom Gehäuse 11 ab.The door handle 20 is constructed of a tubular portion 24 and a part of the length of the tubular portion 24 to this adjoining portion in the form of an angle profile 25, as shown in FIG Fig. 2 , A leg 26 adjacent to the section 24 of the angle section 25 extends approximately parallel to the front of the door 14; connected to the leg 26 via a rounding second leg 27 is rotatably on the side wall 16 of the door. In the in Fig. 2 shown with solid lines position of the door handle 20 is a buffer 28, which forms the conclusion of the lever arm 22, at the front edge of the housing 11 at. As a user pulls lever arm 22, buffer 28 presses against this leading edge and spreads door 14 off housing 11.

Die Stellung des Türgriffs 20 in diesem Zustand ist in Fig. 2 mit gestrichelten Linien dargestellt.The position of the door handle 20 in this state is in Fig. 2 shown with dashed lines.

Fig. 3 zeigt einen Schnitt durch den Türgriff 20 in Höhe der Linie III-III aus Fig. 2. An der Innenseite des Schenkels 27 ist eine Aussparung 30 gebildet, die einen flachen zapfenförmigen Ansatz 31 rings umgibt. Durch den Ansatz 31 verläuft koaxial zur Achse 23 eine Bohrung 32, die vorgesehen ist, um einen Stift für die drehbare Befestigung des Türgriffs 20 aufzunehmen. Die Aussparung 30 geht an ihrem dem Schenkel 26 zugewandten Rand in eine radial zur Achse 23 orientierte Nut 33 über. Fig. 3 shows a section through the door handle 20 at the level of the line III-III Fig. 2 , On the inside of the leg 27, a recess 30 is formed, which surrounds a flat pin-shaped projection 31 rings. Through the projection 31 extends coaxially to the axis 23 has a bore 32 which is provided to receive a pin for the rotatable mounting of the door handle 20. The recess 30 merges at its edge facing the leg 26 into a groove 33 oriented radially with respect to the axis 23.

Fig. 4 zeigt eine Seitenansicht des Türgriffs 20, gesehen von der im montierten Zustand der Tür 14 zugewandten Seite. An beiden Enden der Nut 33 ist der Rand 40 der Aussparung kreisbogenförmig verlängert. Fig. 4 shows a side view of the door handle 20, seen from the mounted in the mounted state of the door 14 side. At both ends of the groove 33, the edge 40 of the recess is extended in a circular arc.

Fig. 5 zeigt eine Metallplatte 50, die vorgesehen ist, um an der Seitenwange 16 der Tür befestigt und in die Aussparung 30 des Türgriffs 20 eingeführt zu werden. Die Metallplatte 50 mit einer Stärke von ca. 1,5 mm hat eine zur Nut 33 komplementäre Kreissegmentform, wobei sich ihr kreisbogenförmiger Rand 53 ununterbrochen über einen Winkel von mehr als 180 ° erstreckt und sein Mittelpunkt zentral in einer Öffnung 51 der Platte 50 liegt. Die Öffnung 51 ist ein Langloch, das im montierten Zustand den Ansatz 31 aufnimmt. Die kürzere Abmessung der Öffnung 51 entspricht mit geringem Spiel dem Durchmesser des Ansatzes 31, und die längere Abmessung D in der Vertikalen ist nur geringfügig größer als d. Zwei weitere Öffnungen 52 dienen zur Befestigung der Platte 50 an der Tür 14. Fig. 5 shows a metal plate 50 which is provided to be attached to the side wall 16 of the door and inserted into the recess 30 of the door handle 20. The metal plate 50 with a thickness of about 1.5 mm has a circular segment shape complementary to the groove 33, wherein its arcuate edge 53 extends continuously over an angle of more than 180 ° and its center is located centrally in an opening 51 of the plate 50. The opening 51 is a slot which receives the neck 31 in the mounted state. The shorter dimension of the opening 51 corresponds with a small clearance to the diameter of the lug 31, and the longer dimension D in the vertical is only slightly larger than d. Two further openings 52 serve for fastening the plate 50 to the door 14.

Fig. 6 zeigt einen horizontalen Schnitt durch den Türgriff 20 und einen Teil der Tür 14 in zusammengebautem Zustand. Vorderseite 17 und Seitenwange 16 der Tür 14 und ein sie verbindender gekrümmter Abschnitt 18 sind einteilig durch ein Blech 60 gebildet, das eine Isolierschicht 61 aus Polyurethanschaum umschließt. Ein Stift 63, der die Lage der Schwenkachse 23 festlegt, erstreckt sich durch die Bohrung 32 des Türgriffs 20. Der Stift 63 hat einen flachen, breiten Kopf 65, der in einem äußeren, breiten Abschnitt der Bohrung 32 bündig aufgenommen ist, einen an den Kopf 65 anschließenden Schaft 66, der einen engeren Abschnitt der Bohrung 32 kreuzt und mit einer Schulter an der Seitenwange 16 anliegt, sowie einen an die Schulter anschließenden Gewindeabschnitt 67. Die Länge des Schaftes 66 ist so bemessen, dass der Türgriff 20 zwischen dem Kopf 65 und der Seitenwange 16 soeben nicht eingeklemmt ist und somit um die Achse 23 frei schwenkbar ist. Fig. 6 shows a horizontal section through the door handle 20 and a part of the door 14 in the assembled state. Front 17 and side wall 16 of the door 14 and a curved portion 18 connecting them are integrally formed by a sheet 60 enclosing an insulating layer 61 of polyurethane foam. A pin 63 which defines the position of the pivot axis 23 extends through the bore 32 of the door handle 20. The pin 63 has a flat, broad head 65, which is received flush in an outer, wide portion of the bore 32, a to the Head 65 subsequent shaft 66 which crosses a narrower portion of the bore 32 and abuts with a shoulder on the side cheek 16, and a subsequent to the shoulder threaded portion 67. The length of the shaft 66 is dimensioned so that the door handle 20 between the head 65th and the side wall 16 has just not been clamped and thus is freely pivotable about the axis 23.

An der Seitenwange 16 der Tür 14 ist an der Innenseite des Blechs 60 eine Verstärkungsplatte 62 angebracht, in der drei Schraubgewinde geformt sind, zwei Stück für nicht dargestellte, durch die Öffnungen 52 der Platte 50 verlaufende Schrauben, und ein drittes Gewinde 65 für den Gewindeabschnitt 67 des Stifts 63. Die durch die Öffnungen 52 geführten Schrauben halten die Platte 50 flach an die Seitenwange 16 gedrückt, so dass ein vorderer Abschnitt 64 der Platte 50 über den Rand der Seitenwange 16 tangential nach vorn übersteht. Der Rand 53 dieses Abschnitts 64 greift formschlüssig in die Nut 33 des Türgriffs 20 ein. Der Rand 53 und die Nut 33 bilden somit eine Anordnung von ineinander eingreifender Führungsschiene und Gegenführungsschiene für die Schwenkbewegung d es Türgriffs 20. Gleichzeitig greift der flache Ansatz 31 in die Öffnung 51 der Platte 50 ein. So wird bei minimalem seitlichen Überstand des Türgriffs 20 eine exakte, kippfreie Führung seiner Schwenkbewegung erreicht.On the side wall 16 of the door 14, a reinforcing plate 62 is mounted on the inside of the sheet 60, in which three screw threads are formed, two pieces for not shown, through the openings 52 of the plate 50 extending screws, and a third thread 65 for the threaded portion 67 of the pin 63. The guided through the openings 52 screws hold the plate 50 flat against the side wall 16 so that a front portion 64 of the plate 50 over the edge of the side wall 16 protrudes tangentially forward. The edge 53 of this section 64 engages positively in the groove 33 of the door handle 20. The edge 53 and the groove 33 thus form an arrangement of intermeshing guide rail and counter guide rail for the pivotal movement d it door handle 20. At the same time, the flat projection 31 engages in the opening 51 of the plate 50 a. Thus, with minimal lateral projection of the door handle 20 an exact, tilt-free guidance of its pivotal movement is achieved.
