Alternativ zu der Klebstoff-Verbindung können die Magnet-Elemente 17 auch durch eine Schraub-Verbindung an den Magnet-Element-Haltern 19 befestigt sein. Beispielsweise können die Aufnahme-Abschnitte 20 der Magnet-Element-Halter 19 im Bereich ihrer Ausnehmung 22 ein Innengewinde aufweisen, in das die mit einem Außengewinde versehenen Magnet-Elemente 17 einschraubbar sind. Die Aufnahme-Abschnitte 20 der Magnet-Element-Halter 19 können auch ein Außengewinde aufweisen, sodass ein zusätzliches Deckel-Element mit einem Innengewinde jeweils auf einen Aufnahme-Abschnitt 20 aufschraubbar ist und das in die Ausnehmung 22 eingelegte Magnet-Element 17 befestigt.As an alternative to the adhesive connection, the magnet elements 17 may also be fastened to the magnet element holders 19 by a screw connection. For example, the receiving portions 20 of the magnetic element holder 19 in the region of its recess 22 have an internal thread into which the magnet elements 17 provided with an external thread can be screwed. The receiving portions 20 of the magnetic element holder 19 may also have an external thread, so that an additional cover element with an internal thread each on a Recording section 20 can be screwed and secured in the recess 22 inserted magnetic element 17.

Die Hebel-Vorrichtungen 18 weisen eine gemeinsame Befestigungsplatte 23 auf, die mit der Innenwand 12 des Tür-Rahmens 13 verschraubt ist.

Ein langer Schenkel 33 des L-förmigen Verbindungs-Elements 31 erstreckt sich im Wesentlichen senkrecht zu dem kurzen Schenkel 32 und der Innenwand 12 in Richtung des Kaminofen-Grundkörpers 1. Das Verbindungs-Element 31 verbindet alle Hebel-Vorrichtungen 18 an ihren jeweiligen ersten Hebelarmen 29.The lever elements 25 of the lever devices 18 each have a first lever arm 29 and an integrally formed with the first lever arm 29 second lever arm 30. The first lever arm 29 extends from the bore 26 of the lever element 25 perpendicular to the lever pivot axis 27 and has at the end facing away from the bore 26 an integrally formed with the first lever arm 29 and in cross-section L-shaped connecting Element 31 on. The L-shaped connecting element 31 is fastened with a short leg 32 on the side of the first lever arm 29 facing away from the inner wall 12. A long leg 33 of the L-shaped connecting element 31 extends substantially perpendicular to the short leg 32 and the inner wall 12 in the direction of the stove base body 1. The connecting element 31 connects all lever devices 18 at their respective first lever arms 29th

An der der Innenwand 12 zugewandten Seite des kurzen Schenkels 32 weist das Verbindungs-Element 31 mehrere voneinander beabstandete Feder-Bolzen 34 auf, an denen jeweils formschlüssig ein Feder-Element 35 in Form einer Schrauben-Feder befestigt ist. An der dem Anschlag 9 gegenüberliegenden Seite des langen Schenkels 33 ist das Griff-Element 15 befestigt. Das Griff-Element 15 umfasst einen U-förmigen Griff 36, eine Griff-Befestigungsplatte 37 und zwei Isolier-Elemente 38. Der Griff 36 und die Griff-Befestigungsplatte 37 erstrecken sich im Wesentlichen entlang des Verbindungs-Elements 31, wobei der Griff 36 an seinen Enden mit der Griff-Befestigungsplatte 37 und den Isolier-Elementen 38 verbunden ist. Die Isolier-Elemente 38 sind formschlüssig an dem langen Schenkel 33 des Verbindungs-Elements 31 befestigt.At the inner wall 12 facing side of the short leg 32, the connecting element 31 has a plurality of spaced-apart spring bolts 34, on each of which a form-fitting spring element 35 is fixed in the form of a helical spring. At the opposite side of the stop 9 of the long leg 33, the handle element 15 is attached. The handle member 15 includes a U-shaped handle 36, a handle mounting plate 37 and two insulating members 38. The handle 36 and the handle mounting plate 37 extend substantially along the connecting member 31, the handle 36 at its ends connected to the handle mounting plate 37 and the insulating elements 38. The insulating elements 38 are positively secured to the long leg 33 of the connecting element 31.

Die zweiten Hebelarme 30 weisen jeweils an dem der Bohrung 26 gegenüberliegenden Ende ein Anschlag-Element 39 auf. Das Anschlag-Element 39 umfasst eine einstückig mit dem zweiten Hebelarm 30 ausgebildete Hülse 40 und eine darin eingesteckte Anschlag-Schraube 41, die durch zwei Schrauben-Muttern 42 relativ zu der Hülse 40 positioniert und befestigt ist.The second lever arms 30 each have a stop element 39 at the end opposite the bore 26. The stopper member 39 includes a sleeve 40 integrally formed with the second lever arm 30 and a stopper screw 41 inserted therein, which is positioned and fixed by two nut nuts 42 relative to the sleeve 40.

Der erste Hebelarm 29 der jeweiligen Hebel-Vorrichtung 18 und das Griff-Element 15 weisen ausgehend von der Hebel-Schwenk-Achse 27 senkrecht zu dieser eine resultierende erste Länge L1 auf. Entsprechend dazu weist der zweite Hebelarm 30 der jeweiligen Hebel-Vorrichtung 18 und das jeweilige Anschlag-Element 39 ausgehend von der Hebel-Schwenk-Achse 27 senkrecht zu dieser eine resultierende zweite Länge L2 auf. Das Verhältnis der ersten Länge zu der zweiten Länge L1 / L2 ist größer als 2, insbesondere größer als 3, und insbesondere größer als 4.The first lever arm 29 of the respective lever device 18 and the handle element 15 have starting from the lever pivot axis 27 perpendicular to this a resulting first length L 1 . Accordingly, the second lever arm 30 of the respective lever device 18 and the respective stop element 39 starting from the lever-pivot axis 27 perpendicular to this a resulting second length L 2 . The ratio of the first length to the second length L 1 / L 2 is greater than 2, in particular greater than 3, and in particular greater than 4.

Im Folgenden wird ausgehend von Figur 5 das Öffnen und Schließen der Kamintür 3 durch die Verschluss-Vorrichtung 16 beschrieben. Figur 5 zeigt die Kamintür 3 im geschlossenen Zustand. Die Magnet-Elemente 17 liegen an dem Anschlag 9 an und befestigen die Kamintür 3 durch die magnetische Anziehungskraft zwischen dem Anschlag 9 und den Magnet-Elementen 17 an den Kaminofen-Grundkörper 1. Die Hebel-Vorrichtungen 18 und das Griff-Element 15 sind in diesem Zustand nicht aktiv. Die Hebel-Elemente 25 verlaufen im Wesentlichen parallel zu der Innenwand 12 des Tür-Rahmens 13. Die Anschlag-Schrauben 41 der Anschlag-Elemente 39 liegen gegen die Befestigungsplatte 23, jedoch nicht gegen den Anschlag 9 an. Die Schrauben-Federn 35 liegen gegenüber der Innenwand 12 des Tür-Rahmens 13 frei.The following is based on FIG. 5 the opening and closing of the chimney door 3 by the shutter device 16 described. FIG. 5 shows the fireplace door 3 in the closed state. The magnetic elements 17 abut against the stop 9 and attach the chimney door 3 by the magnetic attraction between the stopper 9 and the magnetic elements 17 to the stove base body 1. The lever devices 18 and the handle member 15 are in not active in this state. The lever elements 25 extend substantially parallel to the inner wall 12 of the door frame 13. The stop screws 41 of the stop elements 39 are against the mounting plate 23, but not against the stop 9 at. The coil springs 35 are exposed to the inner wall 12 of the door frame 13.

Zum Öffnen der Kamintür 3 wird der Griff 36 des Griff-Elements 15 in Richtung der Kamintür 3 gezogen. Dadurch, dass das Griff-Element 15 an dem Verbindungs-Element 31 und dieses an den ersten Hebelarmen 29 der Hebel-Elemente 25 befestigt ist, werden die Hebel-Vorrichtungen 18 betätigt. Das Griff-Element 15, das Verbindungs-Element 31, die Schrauben-Federn 35 und die ersten Hebelarme 29 werden um die Hebel-Schwenk-Achse 27 in Richtung der Kamintür 3 geschwenkt. Durch die Hebel-Vorrichtungen 18 werden gleichzeitig die zweiten Hebelarme 30 der Hebel-Elemente 25 und die Anschlag-Elemente 39 in Richtung des Anschlages 9 geschwenkt. Durch diesen Schwenkvorgang werden die Anschlag-Elemente 39 solange in Richtung des Anschlages 9 bewegt, bis die Anschlag-Schrauben 41 gegen den Anschlag 9 anschlagen und somit eine Abdrückkraft ausüben, die entgegengesetzt zu der magnetischen Anziehungskraft wirkt. Die wirkende Abdrückkraft F2 ist L1 / L2 mal so groß wie die an dem Griff 36 aufgewendete Zugkraft F1 . Entsprechend dem Hebelgesetz gilt somit L1 / L2 = F2 / F1.To open the fireplace door 3, the handle 36 of the handle element 15 is pulled in the direction of the fireplace door 3. By fastening the handle element 15 to the connecting element 31 and to the first lever arms 29 of the lever elements 25, the lever devices 18 are actuated. The handle element 15, the connecting element 31, the coil springs 35 and the first lever arms 29 are pivoted about the lever pivot axis 27 in the direction of the fireplace door 3. By the lever devices 18, the second lever arms 30 of the lever elements 25 and the stop elements 39 are simultaneously pivoted in the direction of the stop 9. By this pivoting operation, the stop elements 39 are moved as long as in the direction of the stop 9 until the stop screws 41 abut against the stop 9 and thus a Abdrückkraft exercise, which acts opposite to the magnetic attraction. The acting Abdrückkraft F 2 is L 1 / L2 times as large as the force applied to the handle 36 tensile force F 1 . According to the law of levers L 1 / L 2 = F 2 / F 1 .

Ist die Abdrückkraft größer als die wirkende magnetische Anziehungskraft, so lösen sich die Magnet-Elemente 17 von dem Anschlag 9 und die Kamintür 3 öffnet sich um die Schwenk-Achse 10. Dieser Zustand ist in Figur 6 dargestellt. Die Anschlag-Schrauben 41 der Anschlag-Elemente 39 stehen nun gegenüber den Magnet-Elementen 17 vor und die Schrauben-Federn 35 liegen gegen die Innenwand 12 des Tür-Rahmens 13 an, sodass die Schrauben-Federn 35 gespannt sind. Durch die weitere Aufrechterhaltung der Zugkraft auf den Griff 36 wird die Kamintür 3 um die Schwenk-Achse 10 aufgeschwenkt, sodass beispielsweise Holz in den Brennraum 2 nachgelegt werden kann. Gleichzeitig werden das Griff-Element 15, das Verbindungs-Element 31 und die Hebel-Vorrichtungen 18 durch die Spannung der Schrauben-Federn 35 wieder in ihre Ausgangslage gemäß Figur 5 bewegt, wobei die Kamintür 3 nun geöffnet ist.If the pushing-off force is greater than the acting magnetic attraction force, the magnetic elements 17 are released from the stop 9 and the chimney door 3 opens around the pivot axis 10. This state is in FIG. 6 shown. The stop screws 41 of the stop elements 39 are now facing the magnetic elements 17 and the screw springs 35 bear against the inner wall 12 of the door frame 13, so that the coil springs 35 are tensioned. By further maintaining the tensile force on the handle 36, the fireplace door 3 is pivoted about the pivot axis 10, so that, for example, wood can be added to the combustion chamber 2. At the same time the handle element 15, the connecting element 31 and the lever devices 18 by the tension of the coil springs 35 back to their original position according to FIG. 5 moved, with the fireplace door 3 is now open.

Zum Schließen der Kamintür 3 wird auf den Griff 36 eine Druckkraft in Richtung des Kaminofen-Grundkörpers 1 ausgeübt. Dadurch, dass die Anschlag-Schrauben 41 gegen die Befestigungsplatte 23 anliegen, erfolgt keine Schwenkbewegung der Hebel-Vorrichtungen 18. Die Kamintür 3 wird durch die Druckkraft solange um die Schwenk-Achse 10 geschwenkt, bis die Magnet-Elemente 17 derart nahe an den Anschlag 9 bewegt werden, dass die magnetische Anziehungskraft die Magnet-Elemente 17 automatisch an den Anschlag 9 zieht und die Kamintür 3 verschlossen wird.To close the chimney door 3, a pressure force in the direction of the stove base body 1 is exerted on the handle 36. The fact that the stopper screws 41 rest against the mounting plate 23, there is no pivotal movement of the lever devices 18. The chimney door 3 is pivoted by the pressure force around the pivot axis 10 until the magnetic elements 17 so close to the stop 9 are moved, that the magnetic attraction pulls the magnetic elements 17 automatically to the stop 9 and the fireplace door 3 is closed.

Durch die Magnet-Elemente 17 ist die Kamintür 3 einfach, komfortabel und verschleißarm zu öffnen und zu verschließen. Mittels der Hebel-Vorrichtungen 18 ist ein Öffnen der Kamintür 3 komfortabel mit geringem Kraftaufwand möglich. Der erforderliche Kraftaufwand kann durch das Verhältnis der resultierenden Längen L1 / L2 eingestellt werden. Die FederElemente 35 stellen die Hebel-Vorrichtungen 18 nach dem Betätigen des Griff-Elements 15 zum Öffnen der Kamintür 3 automatisch wieder in die Ausgangslage zurück. Die Anschlag-Schrauben 41 der Anschlag-Elemente 39 sind relativ zu den Hülsen 40 positionierbar, sodass der Abstand zwischen den Anschlag-Schrauben 41 und dem Anschlag 9 einstellbar ist. Dadurch kann die Schwenkbewegung um die Hebel-Schwenk-Achse 27 bis zum Anschlagen der Anschlag-Schrauben 41 an den Anschlag 9 auf ein gewünschtes Maß eingestellt werden. Die Magnet-Element-Halter 19 sind mit ihrem Sockel-Abschnitt 21 an der Kamintür 3 befestigt. Durch den kleinen Querschnitt der Sockel-Abschnitte 21 und die Befestigung an der Kamintür 3 wird der Wärmeübergang auf die Magnet-Elemente 17 reduziert. Durch die hochtemperaturbeständige Auslegung der Magnet-Elemente 17 wird verhindert, dass die Magnet-Elemente 17 ihre magnetischen Eigenschaften verlieren. Mittels der hochtemperaturbeständigen Klebstoff-Verbindung sind die Magnet-Elemente 17 in einfacher Weise an den Magnet-Element-Haltern 19 befestigbar. Alternativ dazu ist eine Befestigung in einfacher Weise auch mit einer Schraub-Verbindung möglich. Die Wärmeübertragung auf den Griff 36 wird wirkungsvoll durch die Isolier-Elemente 38 vermieden. Die Kamin-Tür 3 weist im Bereich ihrer Schwenkachse 10 nicht dargestellte Schließfedern auf, die die geöffnete Tür aus Sicherheitsgründen ungefähr über 90 % des Öffnungsbereichs automatisch schließen. Von dieser Position aus werden die Magnet-Elemente 17 wirksam und schließen die Kamin-Tür 3 vollständig. Der unbeaufsichtigte Kamin wird somit automatisch wieder verschlossen. Alternativ zu dem seitlich vorspringenden Griff 36 ist es auch möglich, den Griff nach vorne auf den Benutzer hin vorspringend auszugestalten. Es ist darüber hinaus grundsätzlich möglich, auf das Hebel-Element 25 vollständig zu verzichten. In diesem Fall ist die Öffnung des Kaminofens schwieriger. Die Magnet-Elemente 17 werden dann einfach durch einen Griff von der Gegenplatte abgezogen.By the magnetic elements 17, the fireplace door 3 is easy, comfortable and low-wear to open and close. By means of the lever devices 18 is an opening of the fireplace door 3 comfortable with little effort possible. The required force can be adjusted by the ratio of the resulting lengths L 1 / L 2 . The spring elements 35 automatically return the lever devices 18 to the starting position after the handle element 15 has been actuated to open the chimney door 3. The stopper screws 41 of the stopper members 39 are positionable relative to the sleeves 40 so that the distance between the stopper screws 41 and the stopper 9 is adjustable. Thereby, the pivotal movement about the lever pivot axis 27 can be adjusted to the stop 9 to a desired level to strike the stopper screws 41. The magnetic element holders 19 are fastened with their base portion 21 on the chimney door 3. Due to the small cross-section of the base sections 21 and the attachment to the chimney door 3, the heat transfer to the magnetic elements 17 is reduced. Due to the high temperature resistant design of the magnetic elements 17 prevents the magnetic elements 17 lose their magnetic properties. By means of the high temperature resistant adhesive compound, the magnetic elements 17 can be fastened in a simple manner to the magnetic element holders 19. Alternatively, attachment is possible in a simple manner with a screw connection. The heat transfer to the handle 36 is effectively avoided by the insulating elements 38. The chimney door 3 has in the region of its pivot axis 10 closing springs, not shown, which close the open door for safety reasons about 90% of the opening area automatically. From this position, the magnetic elements 17 are effective and close the chimney door 3 completely. The unattended fireplace is thus automatically closed again. alternative to the laterally projecting handle 36, it is also possible to design the handle projecting forward on the user. It is also possible in principle to completely dispense with the lever element 25. In this case, the opening of the stove is more difficult. The magnet elements 17 are then simply pulled off the counterplate by a handle.

Die beschriebene Verschluss-Vorrichtung 16 für eine Kamintür kann gleichermaßen für eine Ofentür als auch für eine Tür eines Holzlagerraums verwendet werden.The described shutter device 16 for a chimney door can be used equally for an oven door as well as for a door of a wood storage room.

In weiteren Ausführungsbeispielen kann zusätzlich der Anschlag 9 gegenüber der Brennkammer 6 thermisch isoliert sein, sodass eine Wärmeübertragung über den Anschlag 9 auf die Magnet-Elemente 17 vermieden wird. Weiterhin können die Magnet-Elemente 17 in den Magnet-Element-Haltern 19 thermisch isoliert gekapselt sein, sodass die Wärmeübertragung auf die Magnet-Elemente 17 minimiert wird, gleichzeitig jedoch deren magnetische Wirkung nicht beeinträchtigt wird. Alternativ zu den Magnet-Elementen 17 in Form von Dauermagneten sind auch stromdurchflossene Spulen mit einem Kern, beispielsweise aus Eisen, möglich.In further embodiments, the stop 9 may additionally be thermally insulated with respect to the combustion chamber 6, so that heat transfer via the stop 9 to the magnet elements 17 is avoided. Furthermore, the magnetic elements 17 may be thermally isolated in the magnetic element holders 19, so that the heat transfer to the magnetic elements 17 is minimized, but at the same time their magnetic effect is not impaired. As an alternative to the magnetic elements 17 in the form of permanent magnets and current-carrying coils with a core, such as iron, are possible.
