Description

Die Erfindung betrifft eine Kamin- oder Ofentür mit einer vorzugsweise gläsernen, einen Feuerraum begrenzenden Frontplatte, die in seitlichen Führungen unter Verwendung einer Zugvorrichtung vertikal in eine Offen- und in eine Schließstellung bewegbar ist.The invention relates to a fireplace or oven door with a preferably glass, a firebox limiting front panel which is vertically movable in lateral guides using a traction device in an open and a closed position.

Bekannt ist eine Kamintür der eingangs genannten Art aus dem deutschen Gebrauchsmuster 298 17 627 U1. Eine solche Kamin- oder Ofentür bietet nur eine ungenügende Schließstellung, die insbesondere für raumluftunabhängige Kamine oder Öfen nicht geeignet sind. Andere bekannte Ausführungsformen weisen zwar Dichtungselemente entlang der Vertikalführung auf, jedoch spätestens nach wiederholtem Bewegen der Kamintür kann kein Dichtschluß zum Feuerraum hin gewährleistet werden, da die auf und ab bewegte Kamintür durch ihre Bewegung vorhandene Dichtungen abschabt und daher langfristig beschädigt.A chimney door of the type mentioned in the German Utility Model 298 17 627 U1 is known. Such a fireplace or oven door offers only an insufficient closing position, which are not suitable in particular for room air independent fireplaces or stoves. Although other known embodiments have sealing elements along the vertical guide, however, no later than after repeated movement of the chimney door sealing connection can be guaranteed to the firebox because the up and down moving fireplace door abschabt existing seals by their movement and therefore damaged in the long term.

Des weiteren ist aus der DE 295 14 367 U1 ein hochschiebbarer Kamintürrahmen bekannt, der mit beidseitig angeordneten vertikalen Führungen versehen ist sowie an jeder Seite des Rahmens mit einem befestigten flexiblen Zugmittel, das über ein Umlenkrad geführt ist und an dessen einen Ende ein Gegengewicht angeordnet ist. Die Vertikalführungen sind horizontal verschiebbar und zwecks Erzielung eines Schließdruckes auf die Türrahmendichtung über eine schräge Zwangsführung zu schieben, so daß der Türrahmen in die Schließstellung gepreßt wird. Nachteilig hierbei ist, daß die Überführung des Türrahmens in die Schließstellung aufgrund der schrägen Zwangsführung nur mit einem erhöhten Kraftaufwand zu bewerkstelligen ist und darüber hinaus die Türdichtungen durch die Auf- und Absenkbewegung des Türrahmens einem erhöhten Verschleiß ausgesetzt sind.Furthermore, from DE 295 14 367 U1 a Hochschiebbarer fireplace door frame is known which is provided with vertical guides arranged on both sides and on each side of the frame with a fixed flexible traction means which is guided over a guide wheel and at one end of a counterweight is arranged , The vertical guides are horizontally displaceable and push in order to achieve a closing pressure on the door frame seal via an oblique forced operation, so that the door frame is pressed into the closed position. The disadvantage here is that the transfer of the door frame in the closed position due to the oblique forced operation can be accomplished only with an increased effort and beyond the door seals are exposed by the up and lowering movement of the door frame increased wear.

Aus der DE 34 01 332 A1 ist eine vertikal geführte Hebeschiebetür für einen offenen Kamin bekannt, die ebenfalls mit an Seilen geführten Gegengewichten ausgebildet ist, wobei die Seile wiederum über Umlenkrollen geführt sind. Bei dieser Hebeschiebetür ist nachteilig, daß diese in ihrer Schließstellung nicht in eine an die Dichtung herangenäherte Schließstellung gebracht werden kann.From DE 34 01 332 A1 discloses a vertically guided lifting sliding door for an open fireplace is known, which is also formed with ropes guided counterweights, the ropes are in turn guided over pulleys. In this lift-and-slide door, it is disadvantageous that, in its closed position, it can not be brought into a closed position approaching the seal.

Es ist Aufgabe der vorliegenden Erfindung, eine Tür für den Einsatz in einen Kamin oder einen Ofen zu schaffen, die gegenüber dem Stand der Technik verbessert ist und insbesondere langfristig eine gleichbleibend wirksame Schließstellung gewährleisten kann, bei der jedoch die Auf- und Zubewegung der Tür leichtgängig zu vollziehen ist und etwa vorhandene Türdichtungen keinem erhöhten Verschleiß ausgesetzt sind.It is an object of the present invention to provide a door for use in a fireplace or an oven, which is improved over the prior art and in particular can ensure a consistently effective closed position in the long term, but in which the up and Zubewegung the door smoothly is to perform and about existing door seals are not exposed to increased wear.

Zur Lösung dieser Aufgabe zeichnet sich die Kamin- oder Ofentür der eingangs genannten Art dadurch aus, daß die Führungen jeweils mit zumindest einer zum Feuerraum hin ausgerichteten Senkstelle versehen sind, in die in der Schließstellung seitlich der Frontplatte 4 angeordnete Führungselemente 12 in einer Absenkstellung eingreifen und über die die Frontplatte in einer zum Feuerraum hin lageversetzte Schließstellung überführbar ist.To solve this problem, the chimney or oven door of the type mentioned is characterized in that the guides are each provided with at least one oriented towards the firebox lowering, engage in the closed position in the closed position of the front panel 4 arranged guide elements 12 in a lowered position and over which the front panel in a position towards the combustion chamber positionally displaced closed position can be transferred.

Damit ist eine Kamin- oder Ofentür geschaffen, bei der die Kamin- oder Ofentür während ihrer Schließbewegung leichtgängig in den Führungen zu bewegen ist. Sobald eines der Führungselemente die Senkstelle erreicht, taucht es in die Senkstelle ein, ohne daß zuvor irgendwelche schrägen Bahnen zu durchlaufen sind. Es handelt sich mithin um einen Absenkvorgang und mithin um eine Lageversetzung der Tür hin zum Feuerraum und damit hin zu entsprechenden Türdichtungen, die punktuell erfolgt, sobald die Führungselemente die Senkstelle erreicht haben und in eine abgesenkte bzw. lageversetzte Position zu überführen ist. Die vorhandenen Dichtungen werden daher durch die Bewegung nicht verschlissen. Gleichwohl ist eine außerordentlich gute Anpreßkraft auf die Dichtung in der Schließstellung zu gewährleisten, die im übrigen proportional ist eines etwaigen Gegengewichtes bzw. des Gewichtes der Tür selbst. Bevorzugterweise sind die Führungselemente zur Ausübung einer Schwenkkraft senkrecht zur Hauptbewegungsrichtung der Kabinen- oder Ofentür als Schwenkhebelelemente ausgebildet, die zumindest bereichsweise in die Senkstelle eintauchen. Die Senkstelle kann dabei als z.B. Ausnehmung innerhalb eines auf Führungsschiene ausgebildet sein. Eine Vertiefung in einer Führung ist ebenfalls als Senkstelle denkbar. Besonders bevorzugt ist die Kamin- oder Ofentür mit Hebelelementen versehen, bei denen ein Hebelelement zumindest zwei Führungsrollen hat zur Führung der Frontplatte in den Führungen, von denen eine erste koaxial zur Schwenkachse des Hebelarms in eine zweite an dem verschwenkbaren Ende des Hebelelementes angeordnet ist. Dabei ist das Hebelelement mit seinen zwei Führungsrollen bevorzugterweise als Wippe ausgebildet und an vier Stellen eines beispielsweise rechteckförmigen Rahmens vorgesehen, so daß eine der Führungsrolle in die Senkstelle eintauchen kann, während dessen sich die andere Führungsrolle noch an der Führung abstützt.For a fireplace or oven door is created in which the chimney or oven door is easy to move during their closing movement in the guides. As soon as one of the guide elements reaches the lowering point, it plunges into the lowering point, without first having to pass through any oblique paths. It is therefore a lowering operation and thus a positional displacement of the door to the combustion chamber and thus to corresponding door seals, which takes place selectively, as soon as the guide elements have reached the lowering point and is to be transferred to a lowered or positionally offset position. The existing seals are therefore not worn by the movement. Nevertheless, an exceptionally good pressure force to ensure the seal in the closed position, which is proportional to any counterweight or the weight of the door itself. Preferably, the guide elements for exerting a pivoting force perpendicular to the main direction of movement of the cabin or oven door are designed as pivoting lever elements , which dip at least partially into the lowering point. The lowering point can be designed as eg recess within a guide rail. A deepening in a leadership is also conceivable as a lowering point. Particularly preferably, the chimney or oven door is provided with lever elements, in which a lever element has at least two guide rollers for guiding the front panel in the guides, of which a first is arranged coaxially to the pivot axis of the lever arm in a second at the pivotable end of the lever element. In this case, the lever element with its two guide rollers is preferably designed as a rocker and provided at four points of an example rectangular frame, so that one of the leadership can dive into the lowering, during which the other leadership is still supported on the guide.

Während der vertikalen Bewegung der Frontplatte in den Führungen ist die Frontplatte von den typischerweise seitlich vorhandenen Dichtungen beabstandet, so daß diese nicht verschleißen können. Erst unmittelbar vor Erreichen der Schließstellung der Frontplatte greifen die seitlich an der Frontplatte angeordneten Führungselemente in eine ihnen zugeordnete Senkstelle ein, so daß sich die gesamte Frontplatte in Richtung des Feuerraumes bewegt. Dadurch nimmt die Frontplatte ihre - Schließstellung ein und kann den Feuerraum zum Umgebungsraum wirksam begrenzen. Dadurch können auch die Anforderungen an die Dichtigkeit eines Kaminsystems erfüllt werden.During vertical movement of the faceplate in the guides, the faceplate is spaced from the typically laterally existing seals so that they can not wear out. Only immediately before reaching the closed position of the front panel engage the laterally arranged on the front panel guide elements in their associated lowering point, so that the entire front panel moves in the direction of the firebox. As a result, the front panel assumes its closed position and can effectively limit the firebox to the surrounding space. As a result, the requirements for the tightness of a fireplace system can be met.

Die Kamin- oder Ofentür weist eine Zugvorrichtung auf, die die Vertikalbewegung der Frontplatte unterstützt. Beispielsweise kann es sich hierbei um einen Seilzug oder einen Kettenzug handeln, die dergestalt an der Frontplatte angeordnet sind, daß diese annährend schwebend aufgehängt ist. Es ist jedoch auch denkbar, daß die Zugvorrichtung lediglich einen Haltegriff an der Kamin-Frontplatte aufweist, mit dessen Betätigung die Frontplatte hoch bzw. herunter zu schieben ist. Für die Vertikalbewegung der Frontplatte können darüber hinaus auch elektrische oder hydraulische Stellmittel, beispielsweise Zylinder oder Motoren, vorgesehen sein. Desweiteren kann eine zusätzliche Haltevorrichtung vorgesehen sein, die in einer beliebigen Offen- oder auch der Schließstellung der Kamintür eine Bewegung der Frontplatte durch beispielsweise Steckverbindungen zwischen Führungen und Frontplatte verhindert.The chimney or oven door has a pulling device which assists in the vertical movement of the front panel. For example, this may be a cable or a chain hoist, which are arranged on the front panel, that this is suspended suspended almost. However, it is also conceivable that the pulling device only has a handle on the chimney front panel, with the actuation of the front panel is to push up or down. For the vertical movement of the front panel may also be provided electrical or hydraulic actuating means, such as cylinders or motors. Furthermore, an additional holding device may be provided which prevents in any open or closed position of the fireplace door movement of the front panel by, for example, connections between guides and front panel.

Vorteilhafterweise sind die Führungselemente zur Ausübung einer Kraft senkrecht zur Hauptbewegungsrichtung der Tür als Hebelelemente ausgebildet, um seitlich an der Frontplatte angeordnete Führungselemente samt der Frontplatte in die entsprechenden Senkstellen eingreifen zu lassen. Die Frontplatte, die annähernd rechteckig mit zwei gerade verlaufenden Seiten ausgebildet sein kann, weist bei einer vorteilhaften Ausführung der Erfindung im Bereich ihrer vier Ecken seitlich oben und unten Führungselemente auf, die jeweils in eine der zwei auf einer Seite angeordneten Senkstellen eingreifen. Gleichzeitig ist jedoch auch denkbar, eine Frontplatte mit einer nicht planaren und rechteckigen Form zu versehen, sondern beispielsweise gerundete, kreisbogenförmige oder abgewinkelte Formen zu verwenden, die mit oder ohne Rahmen über entsprechende Führungselemente bewegbar ausgebildet sind.Advantageously, the guide elements for exerting a force perpendicular to the main direction of movement of the door are designed as lever elements in order to allow guide elements arranged laterally on the front plate, together with the front plate, to engage in the corresponding countersinks. The front panel, which may be formed approximately rectangular with two straight sides, has in an advantageous embodiment of the invention in the region of its four corners laterally above and below guide elements, each engaging in one of the two arranged on one side lowering points. At the same time, however, is also conceivable to provide a front plate with a non-planar and rectangular shape, but for example, to use rounded, circular arc or angled shapes, which are designed to be movable with or without frame via corresponding guide elements.

Damit die erfindungsgemäße Kamintür besonders einfach baut, ist es bei einer weiteren Ausgestaltung der Erfindung vorgesehen, daß die Hebelelemente durch die Zugvorrichtung der Kamintür kraftbeaufschlagt sind und daß die Führungselemente selbstständig im Bereich der Senkstellen zumindest teilweise in Senkstellen der Führungsschiene eingreifen, um so den Dichtschluß der Frontplatte zum Feuerraum zu gewährleisten.Thus, the fireplace door according to the invention is particularly simple, it is provided in a further embodiment of the invention that the lever elements through the Pulling device of the fireplace door are subjected to force and that the guide elements automatically in the area of the lowering at least partially engage in lowering points of the guide rail so as to ensure the sealing of the front panel to the firebox.

Eine Kamintür weist einen Rahmen auf, der aus zwei seitlichen Rahmenelementen 1 und einem oberen Rahmenelement 2 besteht. Innerhalb der seitlichen Rahmenelemente 1 sind als C-Profil-Führungen bzw. Führungsschienen ausgebildete seitliche Führungen 3 angeordnet, in denen eine Frontplatte 4 vertikal in eine Offen- und in eine Schließstellung bewegbar ist. Diese Vertikalbewegung erfolgt in eine Hauptbewegungsrichtung 5. Eine Zugvorrichtung 6 weist einen Haltegriff 7 auf, der auf einem Rahmen 8 der Frontplatte 4 befestigt ist, und ist darüber hinaus als Seilzugvorrichtung mit einem Seil 9 ausgebildet. Das Seil 9 kann ein Drahtseil sein, es kann sich hierbei allerdings auch in einer anderen Ausbildung der Zugvorrichtung 6 um eine Kette handeln.A fireplace door has a frame consisting of two lateral frame members 1 and an upper frame member 2. Inside the side frame elements 1 are designed as C-profile guides or guide rails formed lateral guides 3, in which a front panel 4 is vertically movable into an open and a closed position. This vertical movement takes place in a main movement direction 5. A pulling device 6 has a handle 7, which is mounted on a frame 8 of the front panel 4, and is also designed as a cable pulling device with a rope 9. The rope 9 may be a wire rope, but this may also be in another embodiment of the traction device 6 is a chain.

Die Zugvorrichtung ist üblicherweise mit einem Gegengewicht 34 dergestalt ausgestattet, daß die Frontplatte 4 annähernd schwebend aufgehängt ist. Durch Ziehen oder Drücken an dem Haltegriff 7 läßt sich die Frontplatte 4 auf einfache Weise vertikal bewegen. Statt einer manuellen Betätigung ist es allerdings auch denkbar, die Frontplatte 4 mithilfe einer mit elektrischen oder hydraulischen Stellmitteln versehenen Zugvorrichtung 6 zu bewegen, wodurch die Bedienung der Kamin- oder Ofentür komfortabler wird.The traction device is usually equipped with a counterweight 34 such that the front panel 4 is suspended almost floating. By pulling or pressing on the handle 7, the front panel 4 can be moved vertically in a simple manner. However, instead of a manual operation, it is also conceivable to move the front panel 4 by means of a traction device 6 provided with electric or hydraulic actuating means, whereby the operation of the chimney or oven door becomes more comfortable.

Die Frontplatte 4 ist in Fig. 1 in der Schließstellung gezeigt, in der sie eine lageversetzte Position zum Feuerraum hin einnimmt. In einer (nicht gezeigten) Offenstellung verhindern zwei Anschläge 11 eine Beschädigung des oberen Rahmenelements 2, bzw. der vorzugsweise mit einer Glasscheibe versehenen Frontplatte 4, die darüberhinaus mit oder ohne Rahmen ausbildbar ist.The front panel 4 is shown in Fig. 1 in the closed position in which it occupies a positionally offset position towards the firebox. In an open position (not shown), two stops 11 prevent damage to the upper frame element 2 or the front panel 4, which is preferably provided with a glass pane, and which can also be formed with or without a frame.

In der Fig. 2 ist erkennbar, daß das dargestellte Ausführungsbeispiel der Erfindung vier Führungselemente 12 aufweist, die seitlich in den Eckbereichen der Frontplatte 4 angeordnet sind.In Fig. 2 it can be seen that the illustrated embodiment of the invention four guide elements 12 which are arranged laterally in the corner regions of the front panel 4.

Die Führungselemente 12 sind auf einem an dem Rahmen 8 der Frontplatte 4 befestigten Profilschlitten 13 angeordnet, sie können jedoch auch direkt auf dem Rahmen 8 der Frontplatte 4 befestigt sein. Eine in einem nicht einsehbaren Bereich der Kamin- oder Ofentür angeordnete Umlenkung 14 lenkt das Seil 9 zum Gegengewicht 34, wobei das Seil 9 einerseits einen zu einem Gegengewicht 34 führenden Seilabschnitt 16, sowie einen zur Frontplatte führenden Seilabschnitt 17 aufweist.The guide elements 12 are arranged on a mounted on the frame 8 of the front panel 4 profile carriage 13, but they can also be mounted directly on the frame 8 of the front panel 4. A arranged in a non-visible area of the fireplace or oven door deflection 14 directs the cable 9 to the counterweight 34, wherein the cable 9 on the one hand leading to a counterweight 34 cable section 16, and a cable leading to the front panel 17 has.

Die Kamin- bzw. Ofentür ist mit genau einem Seilzug versehen, so daß seitlich oberhalb der Frontplatte 4 an den Profilschlitten 13 kleine Umlenkrollen 18 angeordnet sind, die das Seil 9 von einer Seite der Frontplatte 4 zur anderen Seite der Frontplatte 4 führen. Um ein Verkanten der Frontplatte 4 aufgrund der leicht ungleichmäßigen Belastung durch einseitige Ansteuerung des Seilzuges zu verhindern, weist die Kamin- oder Ofentür diametral an den Seiten der Frontplatte 4 angeordnete Seitenführungselemente 19 auf, die als Rollen ausgebildet sind. Bei Ausführungsformen der Erfindung, die jeweils einen Seilzug für jede Seite der Frontplatte 4 aufweisen, werden diese Seitenführungselemente 19 nicht unbedingt benötigt.The fireplace or oven door is provided with exactly one cable, so that laterally above the front plate 4 to the profile slide 13 small guide rollers 18 are arranged, which guide the cable 9 from one side of the front panel 4 to the other side of the front panel 4. To prevent tilting of the front panel 4 due to the slightly uneven load by unilateral control of the cable, the chimney or oven door diametrically on the sides of the front panel 4 arranged side guide elements 19 which are formed as rollers. In embodiments of the invention, each having a cable for each side of the front panel 4, these side guide members 19 are not necessarily needed.

In der (nicht dargestellten) Offenstellung der Kamintür ist die Frontplatte gegenüber dem dahinterliegenden Kamin- oder Ofenbereich durch eine Rückwand 21 abgetrennt, in die eine Aussparung 22 eingebracht ist, um das Seil zur großen Umlenkrolle 14 der Zugvorrichtung 6 zu führen (Fig. 1 und 2).In the open position of the chimney door (not shown), the front panel is separated from the chimney or oven area behind by a rear wall 21, into which a recess 22 is inserted to guide the cable to the large deflection roller 14 of the traction device 6 (FIGS 2).

In der Fig. 2 ist darüber hinaus erkennbar, daß die vier Führungselemente 12 jeweils zwei Führungsrollen 24 und 26 aufweisen, die über eine Platte 27 miteinander verbunden sind (siehe auch Fig. 5). Eine erste Führungsrolle 24 ist koaxial zur Schwenkachse 28 des als Hebelelement ausgebildeten Führungselements 12 angeordnet, während die Führungsrolle 26 an dem verschwenkbaren Ende des Hebelelements angeordnet und fest aber drehbar mit dem Profilschlitten 13 der Frontplatte 4 verbunden ist. Während die Führungsrollen 24 beständig entlang einer vertikalen Linie in den Führungen 3 bewegbar sind, verschwenken die Führungsrollen 26 im Bereich der Senkstellen 29 hin zum Feuerraum und führen damit die Frontplatte 4 in ihre zum Feuerraum hin lageversetzte Schließstellung (Fig. 3). Hierbei können die zweiten Führungsrollen 26 ganz oder zumindest teilweise in der Senkstelle einer Führung 3 angeordnet sein.In addition, it can be seen in FIG. 2 that the four guide elements 12 each have two guide rollers 24 and 26 which are connected to one another via a plate 27 (see also FIG. 5). A first guide roller 24 is arranged coaxially with the pivot axis 28 of the guide element 12 designed as a lever element, while the guide roller 26 is arranged on the pivotable end of the lever element and firmly but rotatably connected to the profile carriage 13 of the front panel 4. While the guide rollers 24 are continuously movable along a vertical line in the guides 3, the guide rollers 26 pivot in the region of the lowering points 29 toward the firebox and thus guide the front plate 4 into its closed position (FIG. Here, the second guide rollers 26 may be wholly or at least partially disposed in the lowering of a guide 3.

Die Senkstellen lassen sich durch einfaches Abkanten eines eingeschnittenen Teils 30 der Führungen 3 erstellen, wodurch gleichzeitig eine Abrollfläche für die Führungsrolle 26 gebildet wird. Gleichzeitig dient eine Kante 31 als Anschlag für die Führungsrollen 26 zur Verhinderung einer weiteren Vertikalbewegung nach unten.The lowering points can be created by simply folding an incised portion 30 of the guides 3, whereby at the same time a rolling surface for the guide roller 26 is formed. At the same time serves an edge 31 as a stop for the guide rollers 26 to prevent further vertical movement down.

Den Führungsrollen 24 und 26 ist jeweils eine Seilbuchse 32 zugeordnet, die der Anlage des vorzugsweise als Drahtseil ausgebildeten Seils 9 der Zugvorrichtung 6 dient. Das Seil 9 liegt dabei an zwei Seilbuchsen 32 eines Führungselementes 12 jeweils auf entgegengesetzten Seiten an, so daß aufgrund der Gewichtskraft der Frontplatte einerseits, sowie des Gegengewichts 34 andererseits durch das gespannte Seil ein Drehmoment an den Führungselementen 12 anliegt. Dieses Drehmoment führt zur Verlagerung der Frontplatte mit der fest am Profilschlitten 13 befestigten Führungsrolle 26 in die Ausnehmung bzw. die Senkstelle 29 der Führungen 3. Typischerweise genügt bereits eine Verlagerung um wenige Millimeter in Richtung des Feuerraumes, um eine Schließstellung zu bewirken. Gleichzeitig drückt das Seil 9 die feste Führungsrolle 24 gegen die Vorderseite der Führung 3, so daß bei der Vertikalbewegung der Frontplatte 4 die Führungsrollen 24 nicht in den zum Feuerraum hin abgesenkten Bereich der Führungen 3 eingreifen. Auf diese Weise ist eine gute Führung der Frontplatte 4 weiterhin gewährleistet.The guide rollers 24 and 26, a cable bushing 32 is associated with each, which serves the plant of preferably designed as a cable rope 9 of the traction device 6. The rope 9 is applied to two cable bushings 32 of a guide element 12 respectively on opposite sides, so that due to the weight of the front panel on the one hand, and the counterweight 34 on the other hand by the tensioned Rope a torque applied to the guide elements 12. This torque leads to the displacement of the front panel with the guide roller 26 fixedly mounted on the profile carriage 13 in the recess or the lowering point 29 of the guides 3. Typically, a displacement already sufficient by a few millimeters in the direction of the combustion chamber to effect a closed position. At the same time the cable 9 presses the fixed guide roller 24 against the front of the guide 3, so that during the vertical movement of the front plate 4, the guide rollers 24 do not engage in the region of the guides 3 lowered towards the combustion chamber. In this way, a good management of the front panel 4 is still guaranteed.

Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung können die Profilschlitten zur Stabilisierung über eine Verbindungstraverse miteinander verbunden sein.In a further advantageous embodiment of the invention, the profile carriage can be connected to each other for stabilization via a connecting beam.

Eine vorstehend beschriebene Kamintür eignet sich hervorragend zur Verwendung in einem Kamin, einer Kaminkassette bzw. als Ofentür in einem Ofen.A chimney door described above is ideal for use in a fireplace, a fireplace cassette or as an oven door in an oven.
