FIG. 1 shows a cooking appliance 40 formed by an oven with a device having a cooking appliance door 14 pivotally mounted in a pivoting direction 10, 12. The cooking appliance 40 has an oven muffle 42 which is arranged in a cooking appliance housing 56 and which encloses a useful space 16 formed by a cooking chamber on five sides. On a sixth side, namely on a front side of the cooking appliance 40, the work space 16 is closed by the cooking appliance door 14 and can be opened by means of the cooking appliance door 14. Furthermore, the cooking appliance 40 has a storage space 18 arranged underneath the oven muffle 42, into which the cooking appliance door 14 can be lowered, guided over a guide system 20 of the device.

Das Führungssystem 20 weist zwei sich grundsätzlich entsprechende, jeweils mit seitlichen Stirnseiten der Gargerätetür 14 in Schwenkrichtung 10, 12 fest und in eine Flächenerstreckung 22 der Gargerätetür 14 beweglich gekoppelte Führungsmittel 24 auf, wobei nur eines der beiden Führungsmittel 24 dargestellt ist. Das Führungsmittel 24 umfasst ein im Wesentlichen U-förmiges Blechteil mit zwei unterschiedlich langen Schenkeln 44, 46, wobei sich der längere Schenkel 44 - in einer Seitenansicht betrachtet - im Wesentlichen koaxial zur Gargerätetür 14 und der kürzere Schenkel 46 beabstandet, achsparallel zur Gargerätetür 14 erstreckt. Das Führungsmittel 24 weist im Bereich eines freien, ersten Endes des kürzeren Schenkels 46 eine Lagerstelle 50 auf, in der ein Bolzen 48 einer mechanischen Energiespeichereinheit 32 der Vorrichtung schwenkbar gelagert ist. Der Bolzen 48 der Energiespeichereinheit 32 ist mit einer in einem Energiespeichergehäuse 52 angeordneten, nicht näher dargestellten Federeinheit gekoppelt. Das Energiespeichergehäuse 52 ist am Gargerätegehäuse 56 befestigt. Die Energiespeichereinheit 32 ist über das Führungsmittel 24 mit der Gargerätetür 14 gekoppelt.The guide system 20 has two basically corresponding, each with lateral end faces of the cooking appliance door 14 in the pivoting direction 10, 12 fixed and in a surface extension 22 of the cooking appliance door 14 movably coupled guide means 24, wherein only one of the two guide means 24 is shown. The guide means 24 comprises a substantially U-shaped sheet metal part with two different lengths of legs 44, 46, wherein the longer leg 44 - viewed in a side view - substantially coaxial with the cooking appliance door 14 and the shorter leg 46 spaced axially parallel to the cooking appliance door 14 extends , The guide means 24 has in the region of a free, first end of the shorter leg 46, a bearing point 50 in which a bolt 48 of a mechanical energy storage unit 32 of the device is pivotally mounted. The bolt 48 of the energy storage unit 32 is connected to one in an energy storage housing 52 arranged, not shown spring unit coupled. The energy storage housing 52 is attached to the cooking appliance housing 56. The energy storage unit 32 is coupled to the cooking appliance door 14 via the guide means 24.

Das Führungsmittel 24 weist im Bereich eines zweiten Endes des kürzeren Schenkels 46 eine weitere Lagerstelle 54 auf, in der das Führungsmittel 24 auf einer im Gargerätegehäuse 56 befestigten Lagerachse um eine raumfeste Schwenkachse 38 schwenkbar gelagert ist.The guide means 24 has in the region of a second end of the shorter leg 46, a further bearing 54, in which the guide means 24 is pivotally mounted on a fixed housing in the cooking appliance 56 bearing axis about a fixed pivot axis 38.

Ferner weist das Führungsmittel 24 an Endbereichen des längeren Schenkels 44 drehbar gelagerte, von Rollen gebildete Wälzkörper 36 auf, über welche das Führungsmittel 24 mit der Gargerätetür 14 beweglich gekoppelt ist. Die Wälzkörper 36 sind in einer - in einer Seitenansicht betrachtet - sich in Längsrichtung der Gargerätetür 14 erstreckenden Führungsnut 58 eines an einer seitlichen Stirnseite der Gargerätetür 14 fest angeordneten Führungsmittels 60 des Führungssystems 20 geführt, so dass von der Gargerätetür 14 ein Drehmoment über das Führungsmittel 60 und über die Wälzkörper 36 auf das Führungsmittel 24 und ein Drehmoment vom Führungsmittel 24 auf die Gargerätetür 14 übertragen werden kann (Figur 2).Further, the guide means 24 on end portions of the longer leg 44 rotatably mounted, formed by rollers rolling elements 36, via which the guide means 24 is movably coupled to the cooking appliance door 14. The rolling elements 36 are in a - viewed in a side view - in the longitudinal direction of the cooking appliance door 14 extending guide groove 58 of a fixed to a side end of the cooking appliance door 14 guide means 60 of the guide system 20 out, so that from the cooking appliance door 14, a torque on the guide means 60th and can be transmitted via the rolling elements 36 to the guide means 24 and a torque from the guide means 24 to the cooking appliance door 14 ( FIG. 2 ).

Das Führungsmittel 24 bildet aufgrund der Beabstandung der Lagerstelle 50 und der Lagerstelle 54 im geschlossenen Zustand der Gargerätetür 14 im Wesentlichen senkrecht zu einer Federkraft 62 der Energiespeichereinheit 32 einen Hebelarm 34 für die Energiespeichereinheit 32, über den die Energiespeichereinheit 32 mit der Federkraft 62 über das Führungsmittel 24 auf die Gargerätetür 14 wirkt und bei geschlossener Gargerätetür 14 ein Drehmoment bzw. eine auf die Gargerätetür 14 wirkende Schließkraft 64 erzeugt.The guide means 24 forms due to the spacing of the bearing 50 and the bearing 54 in the closed state of the cooking appliance 14 substantially perpendicular to a spring force 62 of the energy storage unit 32, a lever arm 34 for the energy storage unit 32 through which the energy storage unit 32 with the spring force 62 via the guide means 24 acts on the cooking appliance door 14 and generates a torque or a closing force 64 acting on the cooking appliance door 14 when the cooking appliance door 14 is closed.

Ferner weist das Führungssystem 20 im unteren Bereich der Gargerätetür 14 in den seitlichen Stirnseiten befestigte sich grundsätzlich entsprechende Führungsmittel 66 auf, von denen wiederum nur eines dargestellt ist. Mittels dem Führungsmittel 66 ist die Gargerätetür 14 mit ihrem unteren Ende entlang einer schematisiert dargestellten, im Gargerätegehäuse 56 befestigten Führungsbahn 26 des Führungssystems 20 geführt. Die Führungsbahn 26 erstreckt sich über eine Vorderseite des Gargerätegehäuses 56 hinaus und weist ausgehend von seinem vorderen Ende ca. über ein Drittel seiner Länge, in einem vorderen Bereich 28 eine gekrümmte, sich an den Nutzraum 16 annähernde Führungsfläche 30 auf. Über ihre restliche Länge ist die Führungsbahn 26 geradlinig, parallel zu einem Nutzraumboden ausgeführt.Furthermore, the guide system 20 in the lower region of the cooking appliance door 14 in the lateral end faces fixed basically corresponding guide means 66, of which in turn only one is shown. By means of the guide means 66, the cooking appliance door 14 is guided with its lower end along a guide rail 26 of the guide system 20 shown schematically and fastened in the cooking appliance housing 56. The guide track 26 extends beyond a front side of the cooking appliance housing 56 and, starting from its front end, has approximately a third of its length, in a front region 28 a curved guide surface approaching the work space 16 30 on. Over its remaining length, the guide track 26 is rectilinear, executed parallel to a utility room floor.

Beim Öffnen des Nutzraums 16 durch einen Bediener wird die Gargerätetür 14 zuerst aus ihrer Schließstellung (Figur 1) in Schwenkrichtung 10 geschwenkt. Die Schwenkbewegung der Gargerätetür 14 wird auf das Führungsmittel 24 übertragen. Das Führungsmittel 24 wird geschwenkt und die Federeinheit der Energiespeichereinheit 32 wird insbesondere durch eine Gewichtskraft 68 der Gargerätetür 14 weiter vorgespannt, so dass ein durch die Energiespeichereinheit 32 vorteilhaft abgebremstes Öffnen der Gargerätetür 14 erzielt wird (Figur 2).When opening the work space 16 by an operator, the cooking appliance door 14 is first moved from its closed position (FIG. FIG. 1 ) pivoted in the pivoting direction 10. The pivoting movement of the cooking appliance door 14 is transmitted to the guide means 24. The guide means 24 is pivoted and the spring unit of the energy storage unit 32 is further biased in particular by a weight force 68 of the cooking appliance door 14, so that an opening of the cooking appliance door 14 which is advantageously braked by the energy storage unit 32 is achieved ( FIG. 2 ).

Die Gargerätetür 14 wird in ihrer Flächenerstreckung 22, d.h. in einer Seitenansicht betrachtet, in Längsrichtung der Gargerätetür 14, relativ zum Führungsmittel 24 verschoben und mittels des Führungsmittels 66 entlang der Führungsbahn 26 geführt. Mit zunehmender Öffnungsstellung reduziert sich der von dem Führungsmittel 24 gebildete Hebelarm 34 auf ein Kleinstmaß, über den die Energiespeichereinheit 32 über das Führungsmittel 24 auf die Gargerätetür 14 wirkt, so dass in einer horizontalen Stellung der Gargerätetür 14 die Energiespeichereinheit 32 nur noch mit einem geringen Drehmoment auf die Gargerätetür 14 wirkt, um eine spielfreie Führung der Gargerätetür 14 zu ermöglichen (Figur 3). Alternativ könnte der Hebelarm 34 jedoch auch in der horizontalen Stellung der Gargerätetür 14 auf Null reduziert werden, wodurch eine durch die Energiespeichereinheit 32 verursachte Reibung vermieden werden könnte.The cooking appliance door 14 is in its planar extension 22, ie viewed in a side view, displaced in the longitudinal direction of the cooking appliance door 14, relative to the guide means 24 and guided by the guide means 66 along the guide track 26. With increasing opening position, the lever arm 34 formed by the guide means 24 is reduced to a minimum, over which the energy storage unit 32 via the guide means 24 acts on the cooking appliance door 14, so that in a horizontal position of the cooking appliance door 14, the energy storage unit 32 only with a low torque acts on the cooking appliance door 14 to allow a play-free guidance of the cooking appliance door 14 ( FIG. 3 ). Alternatively, however, the lever arm 34 could also be reduced to zero in the horizontal position of the cooking appliance door 14, whereby a friction caused by the energy storage unit 32 could be avoided.

Hat die Gargerätetür 14 ihre horizontale Stellung eingenommen (Figur 3), kann dieselbe beim Öffnungsvorgang von einem Bediener über das Führungssystem 20 translatorisch geführt in den Stauraum 18 bewegt werden, wobei eine aufgrund der Schwenkbewegung der Gargerätetür 14 und des Führungsmittels 24 gespeicherte Energie in der Energiespeichereinheit 32 im Wesentlichen konstant bleibt.If the cooking appliance door 14 has assumed its horizontal position ( FIG. 3 ), the same during the opening process by an operator on the guide system 20 translationally guided into the storage space 18 are moved, wherein a stored due to the pivoting movement of the cooking appliance door 14 and the guide means 24 energy in the energy storage unit 32 remains substantially constant.

Beim Schließen des Nutzraums 16 mittels der Gargerätetür 14 wird dieselbe vom Bediener aus dem Stauraum 18 gezogen und anschließend wieder in ihre Schließstellung in Schwenkrichtung 12 geschwenkt. Dabei unterstützt die Energiespeichereinheit 32 den Schließvorgang, indem dieselbe mit der gespeicherten Energie über das Führungsmittel 24 mit einem in Schließrichtung bzw. in Schwenkrichtung 12 wirkenden Drehmoment auf die Gargerätetür 14 wirkt.When closing the work space 16 by means of the cooking appliance door 14, the same is pulled by the operator from the storage space 18 and then pivoted back into its closed position in the pivoting direction 12. In this case, the energy storage unit 32 supports the closing operation by the same with the stored energy via the guide means 24 acts on the cooking appliance door 14 with a torque acting in the closing direction or in the pivoting direction 12.
