In FIG. 1a For example, a perspective view of a conventional Cheminées 17 is shown with a front of the opening 1 'of a combustion chamber 4' positionable disc 19 and FIG. 1b provides a schematic view of the conventional Cheminées 17 according to Fig. 1a with arranged in shafts 39 Schiebezugelementen. In FIG. 1a the fireplace 17 is shown in the open state of the firebox 4 '. The disk 19 can be displaced vertically downwardly in front of the opening 1 'of the combustion chamber 4' by means of a sliding construction 24 along guide rails 20 and thus close it. Or it can be moved upwards and thus the opening 1 ' access, so that the combustion chamber 4 'with fuel (eg wood, coal, pellets, etc.) can be charged. One downside is that, like, out FIG. 1b can be seen, guide rails 20 ', cables 21 and counterweights 25 for holding the disc 19 in the desired position, the side of the fireplace 17, for example, in shafts 39 in the masonry 18 along the firebox 4' of Cheminées 17 are arranged. These parts of the guide rails 20 ', which form the counterpart to the guide rails 20 mounted along the disc 19, and the cables 21 and the counterweights 25 are difficult to access in the event of a defect or during maintenance. In some cases, even a part of the fireplace 17 surrounding masonry 18 must be broken so that the parts of the guide rails 20 ', the cables 21 and the counterweights 25 are accessible. This is associated with high time and cost. Another disadvantage is that the elements of the sliding structure 24 often require a lot of space and due to the complex construction (eg in the case of a cable construction) are prone to failure. Out Fig. 1b is clearly visible that guide rails 20 ', counterweights 25, cables 21 each extend in a slot 39 laterally along the combustion chamber 4' of the fireplace in the masonry 18 and therefore are not readily accessible.

In FIG. 2 is now a perspective view of the inventive device shown. A door 2 is arranged in the open state in a fixedly connected to a combustion chamber 4, for example rectangular, frame 5 pivotally mounted about a vertical axis. The Disk construction 3 is arranged vertically displaceable in the door 2. The disk structure 3 is formed, for example, as a heat-resistant building glass 9. The building glass 9 may be transparent or opaque or formed as a smoked glass disk or with a pattern or a structure. The frame 5 is formed, for example, of metal. The door 2 has a door opening 6 arranged in the region of the opening 1. An edge region of the disk construction 3 is provided with a one-piece or multi-part seal 40, wherein the seal 40 surrounds the edge region of the disk construction 3, in particular the structural glass pane 9, and a further seal 41 corresponding to the seal 40 surrounds an edge region of the combustion chamber 4. As a result, the use in buildings for energy-saving building standards such as Minergie standard is possible because an unwanted air extraction through a Cheminéentzug (not shown), which is associated with heat loss is prevented. It also prevents unwanted odor emissions such as smoke, grill odors, etc. can get over the firebox 4 in the interior 16 of the Cheminéezimmers inside. A one-piece or multi-part trained door leaf 2 'preferably made of metal and / or stone and / or ceramic plates and / or other heat-resistant cover plates is arranged outside or between the door frame 28. The preferably rectangular door opening 6 can be closed by moving the window structure 3 over the entire door opening 6. The shifting takes place, for example, via a lifting, sliding mechanism, completely similar as is known, for example, for opening and closing of sunroofs of cars. The drive of the lifting, sliding mechanism 30 can be done either electrically with or without remote control 31, for example via a motor drive 32, or mechanically, for example via a crank mechanism (not shown) or a ratchet (not shown). The frame 5 fixedly connected to the combustion chamber 4 projects beyond the opening 1 of the combustion chamber 4 on all sides. The height H1 of an upper and / or lower region 7; 7 'of the frame 5 projects beyond the height H2 of the pane construction 3 by at least one respective frame edge 8; 8th'. It is thereby achieved that the displaceable pane construction 3 of the door corresponds to the dimensioning of the frame 5 and there is sufficient space for receiving the pane construction 3, in particular the building glass 9 in the door 2. In the area of the combustion chamber 4 are connections 22; 23 arranged for the supply and discharge of air to ensure optimum combustion behavior of the fuel. It is clear to the person skilled in the art that the door 2 can also be arranged pivotably on the frame 5 about a horizontal axis, the pane construction 3 then being arranged horizontally displaceable in the door 2.

In FIG. 3 is a front view of the inventive device with a view of the firebox 4 shown. The device is shown in the open state, wherein in the door 2, for example, two disc structures 3; 3 'are arranged, which are arranged independently displaceable. By arranged independently displaceable in the door 2 Disc designs 3, 3 'is achieved in that at least one of the disc construction 3' can be used for other purposes independent of the fireplace or furnace. In this case, a disc structure 3 'with audiovisual equipment 10 or kitchen equipment (not shown), or with shelf elements (not shown) or other fasteners (not shown) for receiving items such as fireplace accessories (not shown) such as shovel, brooms, grill utensils , etc. or a disc structure 3 'for decoration purposes for a cozy room ambience conceivable. In FIG. 3 For example, the second disc structure 3 'has an audiovisual device 10, in particular a screen 11 and at least one loudspeaker 12. Further shows FIG. 3 electro-driven parts 13 such as a motor drive 32, guide elements 14 of the disc structures 3; 3 'and cable guides 15, which are arranged in the frame 5. They are used for easy installation of the parts of the disc structures 3; 3 'and are easily accessible in the open state of the door 2 for maintenance or inspection. As already described above, the control of the disk structures 3, 3 'via a remote control 31 is conceivable. In this case, on the one hand, the displacement of the glass pane 9 can be controlled by the remote control 31 and on the other hand with the same remote control 31, the audiovisual device 10, such as screen 11 or speaker 12 are operated. As a result, on the one hand, a closure of the combustion chamber 4 is achieved with respect to an interior 16 of the Cheminéezimmers back and on the other hand, the further disk construction 3 'may be used for consumer audio equipment 10 (such as television, video, games, etc.), computer, internet, etc. The slidable disk structures 3; 3 'are guided, for example along guide elements 14 arranged in the door 2. The guide elements 14 are, for example, designed as U-shaped or S-shaped rails (not shown). A telescopic rail, roller rail, slide rail or profiled rail guide is conceivable in connection with a lifting mechanism as already mentioned above. Preferably, the first pane construction 3 is arranged from an area B1 of the door opening 6 to an upper area B2 of the door 2 above the door opening 6. The second pane construction 3 'is arranged from the area B1 of the door opening 6 into a lower area B3 of the door 2 below the door opening 6. It is thereby achieved that the displaceable disc structures 3, 3 'of the door of the dimensioning of the frame 5 corresponds and sufficient space for receiving the disc structures 3, 3' in the door 2 is present.

How out FIG. 4 becomes clear, closes the first positioned in front of the opening 1 of the furnace 4 disc structure 3 the firebox 4 with respect to an interior 16 of a Cheminéezimmers thanks to the juxtaposition of arranged in the edge region of the disc construction 3 and construction glass 9 seal 40 and the corresponding in the edge region of the firebox 4 arranged seal 41 air flow-tight.
