lappenartige Flammensimulationselemente vorgesehen sind. Über mindestens
eine Lichtquelle innerhalb des Gehäuses werden das Brennstoffbett und die
Flammensimulationselemente beleuchtet.A device known from GB

Um die Flammensimulationselemente zu bewegen, ist ein Gebläse vorgesehen, das die Elemente in ihrer Längsrichtung anströmt und dadurch für eine züngelnde Flatterbewegung sorgt.

Aus der GB-A-2 298 073 ist eine Vorrichtung zur Flammensimulation bekannt, die ein Gehäuse aufweist, in welchem zur Feuersimulation ein künstliches Brennstoffbett angeordnet ist. Auf eine reflektierende Fläche werden Flammensimulationselemente in Form von starren Folienstreifen über eine Lichtquelle eingespiegelt. Die Reflektionsfläche befindet sich dabei hinter dem Brennstoffbett. Die folienartigen, starren Streifen befinden sich auf einem rotierenden Trägerelement. Damit ist jedoch nur eine künstlich wirkende Flammensimulation erzeugbar.A device for flame simulation is known from GB-A-2 298 073, which has a housing in which an artificial fire simulation Fuel bed is arranged. Be on a reflective surface Flame simulation elements in the form of rigid film strips over a Mirrored light source. The reflective surface is behind the Fuel bed. The film-like, rigid strips are on one rotating support element. However, this is only an artificial one Flame simulation can be generated.
Aus US-A-4 890 600 geht ebenfalls eine Vorrichtung zur künstlichen Simulation eines Feuers hervor, bei welcher die auf einem rotierenden Trägerelement angeordneten Flammensimulationselemente im Bereich des Brennstoffbettes angeordnet sind. Die Flammensimulationselemente sind dabei streifenartig und ebenfalls starr ausgebildet, so daß damit auch nur ein künstlich wirkendes Flammenbild erzeugbar ist.From US-A-4 890 600 there is also an artificial simulation device a fire, in which the on a rotating support member arranged flame simulation elements in the area of the fuel bed are arranged. The flame simulation elements are strip-like and also rigid, so that it is only an artificial one Flame pattern can be generated.
Diese bekannte Vorrichtung ist insofern nachteilig, als die Flammensimulation nur ein ziemlich einseitiges und realitätsfremdes Bild erzeugen kann.This known device is disadvantageous in that the flame simulation can only produce a fairly one-sided and unrealistic picture.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit den Merkmalen
des Oberbegriffes des Patentanspruchs 1 derart weiterzubilden, daß die
Flammensimulation lebendiger, vielseitiger und realitätsnaher erscheint. The invention has for its object a device with the features
to develop the preamble of
Diese Aufgabe wird durch die im kennzeichnenden Teil von Anspruch 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of
Als Kern der Erfindung wird es angesehen, den Träger für die streifen-, zungen- oder lappenartigen oder auf sonstige Weise ausgebildeten Flammensimulationselemente kontinuierlich oder diskontinuierlich zu bewegen. Dazu ist ein motorischer Antrieb vorgesehen. Über den motorischen Antrieb des Trägerelementes wird erreicht, daß laufend andere, auch unterschiedlich geformte oder eingefärbte Flammensimulationselemente eingespiegelt werden können, wohingegen beim Stand der Technik in nachteiliger Weise immer die gleichen Flammensimulationselemente in ihren unterschiedlichen Bewegungsstadien als Bild zu sehen sind.The essence of the invention is considered to be the support for the strip-like, tongue-like or flap-like or otherwise formed flame simulation elements continuously or move discontinuously. A motor drive is provided for this. The motor drive of the carrier element ensures that others, also continuously differently shaped or colored flame simulation elements reflected can be, whereas in the prior art always the disadvantage same flame simulation elements in their different stages of movement as Picture can be seen.
Das Bild der Flammensimulationselemente wird dadurch bunter, variantenreicher und die Flammensimulation insgesamt angenehmer für den Betrachter. Beispielsweise ist es denkbar, unterschiedliche rot, gelb, grün oder blau eingefärbte Flammensimulationselemente in den Einspiegelungsbereich zu bewegen, wodurch eine Farbvariation der Flammen erreicht wird, ohne daß unterschiedlich eingefärbte Beleuchtungsquellen ein-, ausgeschaltet oder gedimmt werden müssen.The image of the flame simulation elements is thus more colorful, more varied and the Overall flame simulation more pleasant for the viewer. For example, it is conceivable different red, yellow, green or blue colored flame simulation elements in to move the reflection area, causing a color variation of the flames is switched on, off or without differently colored lighting sources must be dimmed.
Bei der Erfindung ist es auch möglich, unterschiedlich lange oder unterschiedlich geformte Flammensimulationselemente zu verwenden, so daß einmal große Flammen und einmal nur kleine Flämmchen aus dem Brennstoffbett herauszuschlagen scheinen.In the invention it is also possible to have different lengths or shapes Flame simulation elements to be used, so that once large flames and once only small flames seem to knock out of the fuel bed.
Es ist natürlich auch möglich, nur gleicheingefärbte Flammensimulationselemente zu verwenden und unterschiedliche Farben durch Lichtquellen in unterschiedliche Farbe und/oder mit farbigen Vorsatzblenden zu erzielen.It is of course also possible to use only flame simulation elements of the same color and different colors from light sources in different colors and / or to achieve with colored front panels.
Unterschiedliche motorische Antriebe sind denkbar, so z.B. ein Warmluftmotor, der v orteilhafterweise dann eingesetzt werden kann, wenn die Vorrichtung mit einer Heizquelle versehen ist. Ferner sind auch hydraulische Antriebe oder Aufziehmotoren mit Federaufzug oder Gewichtsauftzug möglich. Different motor drives are conceivable, e.g. a warm air engine, which is advantageous can then be used when the device with a heat source is provided. Hydraulic drives or winding motors with spring windings are also available or weight lift possible.
Das Trägerelement kann nach Art einer umlaufenden Walze ausgebildet sein. Eine derartige Vorrichtung ist einfach herzustellen und anzutreiben. Die Flammensimulationselemente werden sich im oberen Bereich der umlaufenden Walze auf die Oberfläche der Walze legen und dann durch die Schwerkraft gezogen von der Oberfläche der Walze lösen, so daß sie eine sprunghafte Bewegung vornehmen. Wird diese in das Betrachtungsbild eingeblendet, so wird dann ein besonders lebendiges Flammenbild erzielt.The carrier element can be designed in the manner of a rotating roller. Such one Device is easy to manufacture and drive. The flame simulation elements will lie on the surface of the roller in the upper area of the rotating roller and then pulled by gravity from the surface of the roller so that they make a sudden movement. If this is shown in the image, a particularly lively flame picture is then achieved.
Es ist aber auch möglich, das Trägerelement als umlaufendes Band zu gestalten. Dadurch ist die Fläche des Trägerelementes vergrößert, so daß mehr und unterschiedlichere Flammensimulationselemente auf der Oberfläche des Trägerelementes angeordnet werden können.But it is also possible to design the carrier element as a circumferential band. Thereby the area of the support element is enlarged, so that more and different flame simulation elements can be arranged on the surface of the carrier element.
Ferner ist es auch möglich, mehrere trommel- oder radartige Trägerelemente auf einer motorisch angetriebenen Welle anzuordnen oder mehrere trommel- oder radartige Trägerelemente auf einer Achse zu lagern und gesondert oder in Gruppen anzutreiben. Der Antrieb erfolgt bei der letzteren Lösung nicht über die Achse, sondern z.B. peripher durch motorische Einzelantriebe, die über oder hinter den Trägerelementen so angeordnet sind, daß sie nicht mit eingespiegelt werden.Furthermore, it is also possible to have several drum or wheel-like carrier elements on one motor-driven shaft to arrange or several drum or wheel-like support elements to be stored on one axis and to be driven separately or in groups. The drive in the latter solution, it does not take place via the axis, but e.g. peripheral by motor Individual drives that are arranged above or behind the support elements so that they not be reflected.
In diesem Falle ist es auch möglich, die Trägerelemente mit unterschiedlichen Umlaufgeschwindigkeiten oder unterschiedlichen Drehrichtungen anzutreiben, wodurch das Flammenbild noch variantenreicher wird. Auch ein drehoszillierender oder hin- und hergehender Antrieb ist grundsätzlich möglich.In this case, it is also possible for the carrier elements to have different rotational speeds or to drive different directions of rotation, which causes the flame pattern becomes even more varied. Also a rotating oscillating or back and forth Drive is basically possible.
Vorteilhafterweise ist es auch möglich, das Trägerelement nach Art einer umlaufenden Nockenwelle auszubilden, so daß die Flammensimulationselemente von der Drehachse her unterschiedliche Abstände aufweisen, wodurch wiederum unterschiedliche Bewegungsgeschwindigkeiten der Flammensimulationselemente (abhängig vom Abstand der Drehachse) erzielt werden. Auch eine Trommel mit abschnittsweise unterschiedlichen Durchmessern ist im Rahmen der Erfindung denkbar.Advantageously, it is also possible to have the carrier element in the manner of a rotating one Form camshaft so that the flame simulation elements from the axis of rotation have different distances, which in turn means different speeds of movement the flame simulation elements (depending on the distance of the axis of rotation) be achieved. Also a drum with different diameters in sections is conceivable within the scope of the invention.
Ferner ist es auch möglich, dem Trägerelement neben seiner umlaufenden Bewegung eine axiale Versatz- oder Oszillationsbewegung aufzuprägen. Dies läßt sich dadurch erreichen, daß das Trägerelement auf einer Welle gelagert ist, die gegen Federkraft um einen gewissen Betrag axial verschiebbar ist. An einem Ende der Welle kann dann ein Nockenantrieb vorgesehen sein, der mit unterschiedlichen Geschwindigkeiten oder abhängig von einer Kulissenführung eine hin- und hergehende Versatzbewegung des Trägerelements besorgt.Furthermore, it is also possible to provide the carrier element with a rotating movement axial offset or oscillation movement. This can be achieved that the carrier element is mounted on a shaft which against spring force by a certain amount Amount is axially displaceable. A cam drive can then be attached to one end of the shaft be provided at different speeds or depending on one Backstage guide a reciprocating offset movement of the support element worried.
Grundsätzlich ist es auch denkbar, die Trägerelemente anzuströmen, so daß sie neben der motorisch angetriebenen und durch Schwerkraft ausgelösten Pendelbewegung eine zusätzliche Flatterbewegung vollziehen. Dazu ist das Trägerelement mit Luftaustrittsöffnungen versehen und ein Gebläse strömt den Innenbereich des Trägerelements an.Basically, it is also conceivable to flow against the carrier elements, so that they next to the an additional pendulum movement driven by motor and gravity Carry out flutter movement. For this purpose, the carrier element with air outlet openings provided and a fan flows onto the inner region of the carrier element.
Um die Vorrichtung bzw. das Flammenbild noch "lebensnaher" zu gestalten, kann der motorische Antrieb mit einem Zufallsgenerator zur Geschwindigkeitsvariation verbunden sein, so daß einmal die Trägerelemente langsam und dann wieder schnell angetrieben werden.In order to make the device or the flame image even more "lifelike", the motor drive connected to a random generator for speed variation be so that the carrier elements are driven slowly and then quickly again become.
Weiterhin liegt es im Rahmen der Erfindung, eine Programmsteuerung vorzusehen, die sowohl Licht- als auch motorische Bewegungen ansteuert. In diesem Falle sind unterschiedliche Feuerprogramme abrufbar, z.B. das prasselnde Feuer, das dann entsteht, wenn sehr trockenes Weichholz verwendet wird oder das gemächliche langsame Abbrennen von Eichenholz oder Buchenscheiten.Furthermore, it is within the scope of the invention to provide program control that controls both light and motor movements. In this case, they are different Fire programs available, e.g. the crackling fire that arises when very dry softwood is used or the slow, slow burning of Oak or beech logs.
Zur Einspiegelung der Flammensimulationselemente auf das Brennstoffbett ist mindestens ein reflektierendes Element angeordnet, vorzugsweise befinden sich mehrere reflektierende schräggestellte Scheiben übereinander, die auch unterschiedliche Neigungswinkel aufweisen können, so daß aus unterschiedlichen Betrachtungswinkeln jeweils eine Mehrzahl von Flammensimulationselementen auf das Brennstoffbett projiziert wird.At least to reflect the flame simulation elements on the fuel bed a reflective element arranged, preferably there are several reflective slanted discs one above the other, which also have different angles of inclination can, so that from different viewing angles a plurality of each Flame simulation elements are projected onto the fuel bed.
Sind die Scheiben nach oben gewölbt oder bombiert, dann wird ein negativer Effekt vermieden, der dann auftritt, wenn der Betrachter vor der Vorrichtung hin- und hergeht und das Bild der Flammensimulationselemente ansieht. Bei flachen Glasscheiben würden diese nämlich hin und her wandern, bei einer Bombierung der Glasscheiben hingegen wird dieser hin und hergehende Flammeneffekt unterdrückt. If the panes are curved or domed, a negative effect is avoided, which occurs when the viewer paces back and forth in front of the device and looks at the image of the flame simulation elements. With flat glass panes, this would namely hike back and forth, however, if the glass panes are curved, this becomes back and forth flame effect suppressed.
Zur Einstellung der Geschwindigkeit oder zur Programmierung der Programmsteuerung können Eingabeelemente vorgesehen sein, wie beispielsweise Programmwahlschalter, Geschwindigkeitsregeler, Helligkeitsregler und dgl..For setting the speed or programming the program control input elements can be provided, such as program selector switches, speed controllers, Brightness control and the like ..
Es ist auch möglich, in die Programmsteuerung eine Zeitsteuerung einzubauen, die die Geschwindigkeit oder die Intensität der Lichteffekte nach Art einer abfallenden Kurve reduziert, so daß der Eindruck eines schön langsam abbrennenden Feuers entsteht. Der Endzustand des Programms entspricht dann einem Gluthaufen ohne Flammen.It is also possible to incorporate a time control into the program control, the speed or reduce the intensity of the lighting effects like a sloping curve, so that the impression of a nice slowly burning fire is created. The final state the program then corresponds to a pile of embers without flames.
Eine Verbesserung der optischen Qualität der Einspiegelung wird durch eine Diffusorscheibe erreicht, die unter dem Trägerelement angeordnet ist.A diffuser disc improves the optical quality of the reflection reached, which is arranged under the carrier element.
