Shielding flap for open chimneys

The innovation "refers to a barn door for open fires, in particular for a fireplace inserts and provided with feed and return connections for air or water circulation _f Aoppelwandigen housing with fireplaces opening in the front surface.

not too favorable efficiency nor more. In consideration • Up to now, efforts have apparently always been made to obtain the necessary fuel for the fuel, which as a rule is to be inserted in large chunks to keep the large fireplace opening free.

Q The innovation is accordingly based on the task of a shielding plate For open fireplaces, in particular to create xamine inserts, with the one hand the size of the fireplace opening remains available for inserting large pieces of fuel, but on the other hand ensures that only the absolutely necessary amount of air is supplied in the area of the fireplace opening.

This task is with a AbscMrmplatte according to the innovation solved in that the on the front surface of the fireplace can be folded up or can be removed from the fireplace opening The flap is dimensioned in such a way that at least the upper third of the fireplace opening is covered.

Advantageous further training results from the Uhteran- ! Sayings.

The novel solution is of course not intended to exclude the use of other control elements such as adjustable throttle valves in the exhaust area of the K »m <v> g or the like

can come. The new barn door prevents unreasonably large amounts of hot air in any case "They are sucked out of the room in question", of course need to be replaced somehow. The flap is therefore advantageous already in the inflow area of the fireplace opening Q made sure that as little air as possible is sucked in that does not go into the combustion, which means that heat is lost reduced and the efficiency of the fireplace is improved.

The novel barn door will be described in more detail below with reference to the graphic representation of an exemplary embodiment explained.

It show schematically

Fig. 1 shows a section through the front surface of an open Ki * and

Fig. 2 is a view of the front surface with fireplace opening and shielding plate.

¥ ie can be seen from Fig. 1, the 3 * is the Abschinaklappe at least one third of the cross-section of the fireplace opening 2 covers in the upper area, can be folded up at a joint 6 with the front surface 1 ass Κβκϊηκ and connected protrudes slightly obliquely downward from the plane of the front surface. The barn door is formed by side flank surfaces 7

3 a hood, so to speak.

Of course, this flap or hood could also, simply withdrawable, -as mentioned, on. appropriate brackets attached being.

As shown, the screening flap 3 is resiliently connected to an inner flap 4, the peripheral edge 4 of which is provided with a sealing element 5. In the folded-down state of the gutter flap 3, the edge 4 ¹ or the sealing element 5 is pressed against ^{the edge 2 1 of the fireplace opening 2.}

If you want to add fuel, the barn door 3 simply folded up and held up (of course a handle can easily be provided) or with a one-piece bracket simply removed and brought back into the position shown after loading has been completed, in which only the remaining part of the fireplace opening remains free.

The shielding plate 3 of course also has the advantage that it often spurts out obliquely upwards from the fireplace Embers or sparks can be caught.

The side flank surfaces 7, bzu pulled up to the front surfaces 1 (possibly with the interposition of the sealing element 5). 7 'either from the screening flap 3 and / or from the inner flap h also have the advantage that at the same time the weld seam, which runs along the opening edge 2 ″ of the fireplace opening 2, is covered for the most part.

It is also possible to allow additional cover webs 7 ″ (indicated by dashed lines in FIGS. 1, 2) to continue running below the flaps 3 bzu. K,
