Erfindungsgemäß wird die Aufgabe durch eine Einrichtunggelöst, die zwischen die Seitenholme einer Tür eingespannt wird. Die erfindungsgemäße Einrichtung ist dabei so ausgebildet, dass sie in ihrer Länge in der Richtung, die in ihrer Einbaulage der Breitenrichtung der Tür entspricht, veränderlich ist. Erfindungsgemäß ist dabei eine Spannvorrichtung vorgesehen, die diese Längenänderung der Einrichtung bewirkt und es ermöglicht, die Einrichtung zwischen den Seitenholmen eines Türrahmens kraftschlüssig zu fixieren.According to the invention the object is achieved by a device which is clamped between the side rails of a door. The device according to the invention is designed so that it is variable in its length in the direction that corresponds in its installation position of the width direction of the door. According to the invention a clamping device is provided which causes this change in length of the device and makes it possible to fix the device between the side rails of a door frame frictionally.
Erfindungsgemäß verfügt die Einrichtung dabei über zwei Luftdurchtrittsöffnungen, die zum einen den Anschluss oder die Durchführung von Luftschläuchen ermöglichen, zum anderen vorteilhafterweise durch Deckel verschließbar sind, und ferner - falls eine Luftdurchtrittsöfnnung mit einem Schlauch versehen ist - durch Offenlassen der anderen Luftdurchtrittsöffnung die Möglichkeit bietet, über diese dem Schwarzbereich Frischluft zuzuführen. Vorteilhafterweise sind an der Einrichtung Aufnahmeelemente für Adapterstücke vorgesehen, die dazu dienen, die Einrichtung in ihrer längenveränderlichen Richtung zu verlängern, so dass sich die Möglichkeit ergibt, durch die Adapterstücke eine Grobanpassung der Länge der Einrichtung an Türen unterschiedlicher Breite vorzunehmen. Einrichtung und Adapterstücke sind vorzugsweise aus einem metallischen Werkstoff gefertigt, bei dem es sich beispielsweise um einen nicht rostenden Stahl handelt. Vorzugsweise handelt es sich bei Einrichtung und Adapterstücken um tafelartige Gebilde, die aus Blechteilen gefertigt sind.According to the invention, the device has two air passage openings, which allow for the connection or the passage of air hoses, on the other advantageously be closed by a lid, and further - if an Luftdurchtrittsöfnnung is provided with a hose - by leaving open the other air passage opening offers the possibility to supply fresh air to the black area via this. Advantageously, receiving elements for adapter pieces are provided on the device, which serve to extend the device in its variable-length direction, so that there is the possibility of making a coarse adjustment of the length of the device to doors of different widths through the adapter pieces. Device and adapter pieces are preferably made of a metallic material, which is for example a stainless steel. The device and adapter pieces are preferably sheet-like structures made of sheet metal parts.
Die Einrichtung liegt mit ihren Rändern an den seitlichen Holmen des Türrahmens an, wobei vorzugsweise Dichtelemente an den Rändern der Einrichtung vorgesehen sind, die für die Abdichtung zwischen Türrahmen und Einrichtung sorgen. Bei den Dichtelementen kann es sich beispielsweise um Kunststofflippen handeln, die vorzugsweise aus einem weichen Kunststoff, beispielsweise aus einem Gummimaterial, gefertigt sind, so dass sowohl eine hinreichende Abdichtung wie auch ein ausreichender Kraftschluss der Einrichtung mit dem Türrahmen ermöglicht wird, allerdings gleichzeitig auch eine eventuelle Beschädigung auch eines empfindlichen Türrahmens vermieden wird. Entsprechende Dichtelemente können ebenfalls am in Einbaulage oberen Rand der Einrichtung sowie an den Rändern der Adapterstücke und/oder den Rändern der Luftdurchtrittsöffnungen vorgesehen sein.The device rests with its edges on the side rails of the door frame, wherein preferably sealing elements are provided at the edges of the device, which provide the seal between the door frame and device. The sealing elements may be, for example Plastic lips act, which are preferably made of a soft plastic, such as a rubber material, so that both a sufficient seal as well as a sufficient adhesion of the device with the door frame is made possible, but at the same time a possible damage even a sensitive door frame is avoided. Corresponding sealing elements can likewise be provided on the upper edge of the device in the installed position and on the edges of the adapter pieces and / or the edges of the air passage openings.
Vorteilhafterweise wird die Längenveränderlichkeit der Einrichtung dadurch realisiert, dass die Einrichtung zwei tafelartige, verschieblich miteinander verbundene Schiebeelemente aufweist. Die Schiebeelemente sind dabei derart gestaltet, dass sie sich überlappen und im Überlappungsbereich beispielsweise über Führungsschienen miteinander verbunden sind. Die Schiebeelemente können mit der Spannvorrichtung gegeneinander bewegt werden, wodurch die Längenveränderlichkeit der Einrichtungbewirkt wird.Advantageously, the variable in length of the device is realized in that the device has two panel-like, slidably interconnected sliding elements. The sliding elements are designed such that they overlap and are connected to each other in the overlapping area, for example via guide rails. The sliding elements can be moved with the clamping device against each other, whereby the Längenveränderlichkeit the device is effected.
Bei der Spannvorrichtung kann es sich vorteilhafterweise um ein arretierbares Zahnrad handeln, das in eine Lochschiene eingreift, wobei Lochschiene und Zahnrad jeweils mit einem der beiden Schiebeelemente verbunden sind. Dabei kann die Lochschiene alternativ als Profilierung eines der Schiebeelemente ausgeführt sein, die einen Eingriff des Zahnrads ermöglicht. Vorteilhafterweise wird das Zahnrad durch einen schwenkbaren Hebel betätigt, der mit einem Rastelement in das Zahnrad eingreift. Das Rastelement ist dabei bevorzugt derart ausgebildet, dass es lediglich bei der Bewegung des Hebels in Spannrichtung in das Zahnrad eingreift und so eine Art Ratschenmechanismus zum Einspannen der Einrichtung bildet, wobei es vorteilhafterweise zum Lösen der Einrichtung durch ein weiteres Betätigungselement außer Eingriff mit dem Zahnrad gebracht werden kann. Im Hinblick auf eine ergonomische Bedienung ist das Betätigungselement zum Lösen der Spannvorrichtung derart an dem Hebel zum Spannen der Spannvorrichtung angebracht, dass beide mit der gleichen Hand einhändig bedient werden können.The tensioning device can advantageously be a lockable toothed wheel which engages in a perforated rail, with the perforated rail and the toothed wheel each being connected to one of the two sliding elements. In this case, the hole rail may alternatively be designed as a profiling of one of the sliding elements, which allows engagement of the gear. Advantageously, the gear is actuated by a pivotable lever which engages with a locking element in the gear. The locking element is preferably designed such that it engages only in the movement of the lever in the clamping direction in the gear and so forms a kind of ratchet mechanism for clamping the device, and it is advantageously brought to release the device by another actuator out of engagement with the gear can be. In view of ergonomic operation, the operating element for releasing the tensioning device is attached to the lever for tensioning the tensioning device so that both can be operated with one hand by the same hand.
Im Hinblick auf einen im Vergleich zur Gesamtlänge der Einrichtung möglichst großen Verstellbereich der Länge der Einrichtung ist es vorteilhaft, die Luftdurchtrittsöffnungen im Bereich der voneinander weg weisenden Enden der Schiebeelemente vorzusehen. Vorteilhafterweise sind die Schiebeelemente dabei an ihren aufeinander zu weisenden Seiten entsprechend den Umrissen der Luftdurchtrittsöffnungen konturiert. Dies bedeutet, dass die Kontur so gestaltet ist, dass beispielsweise bei kreisrunden Luftdurchtrittsöffnungen die aufeinander zu weisenden Enden der Schiebeelemente ebenfalls eine kreisbogenartige Kontur aufweisen, so dass sich zum Einen eine größtmögliche Zusammenschiebbarkeit ergibt, zum Anderen im weitestmöglich ausgezogenen Zustand im Bereich des oberen und unteren Randes der Einrichtung gleichzeitig ein größtmöglicher Überlappungsbereich besteht. Dies ist vorteilhaft, da in diesem Überlappungsbereich die Führung der Schiebeelemente ineinander realisiert werden kann. Eine hierfür zweckdienliche Konturierung der aufeinander zu weisenden Enden der Schiebeelemente muss nicht zwangsläufig die Kontur der Luftdurchtrittsöffnungen nachbilden, es genügt beispielweise auch, die Kontur in der Art einer rechteckigen Ausnehmung zu gestalten, so dass sich im zusammengezogenen Zustand die Luftdurchtrittsöffnung des einen Schiebeelementes zumindest teilweise im Bereich der rechteckigen Ausnehmung des anderen Schiebeelementes befindet, während gleichzeitig im ausgezogenen Zustand des Schiebeelementes die nicht ausgenommenen Bereiche einen Überlappungsbereich beider Schiebeelemente für die vorteilhafte Führung der Verschiebebewegung bereitstellen. Die ergänzend verwendbaren Adapterstücke weisen an ihren einander zugewandten Enden eine entsprechende, beispielsweise halbkreisförmige oder rechteckige Kontierung auf.With regard to an adjustment range of the length of the device that is as large as possible compared with the overall length of the device, it is advantageous for the air passage openings to be in the region of the ends of the device facing away from one another Provide sliding elements. Advantageously, the sliding elements are contoured on their sides facing each other according to the contours of the air passage openings. This means that the contour is designed so that, for example, in circular air passage openings the mutually facing ends of the sliding elements also have a circular arc-like contour, so that on the one hand a maximum Verschschiebbarkeit results, on the other hand in the extended state as possible in the region of the upper and lower Edge of the facility at the same time the largest possible overlap area exists. This is advantageous because in this overlapping region, the guidance of the sliding elements can be realized in each other. A purposeful contouring of the mutually facing ends of the sliding elements does not necessarily simulate the contour of the air passage openings, it is sufficient, for example, to make the contour in the manner of a rectangular recess, so that in the contracted state, the air passage opening of a sliding element at least partially Area of the rectangular recess of the other sliding element is located, while at the same time in the extended state of the sliding element, the non-recessed areas provide an overlap region of both sliding elements for the advantageous guidance of the sliding movement. The supplementary usable adapter pieces have at their ends facing each other on a corresponding, for example, semicircular or rectangular account assignment.
Zur Abschottung eines Raumes wird die Einrichtung mit verschlossenen Luftdurchtrittsöffnungen am oberen Ende einer Türöffnung zwischen die Seitenholme einer Tür geklemmt. An der Einrichtung werden vorzugsweise an ihrem unteren Rand Kunststofffolien, Kunststofflamellen oder ähnliche geeignete Elemente vorgesehen, die im Folgenden als Vorhang bezeichnet, einen hinreichend luftdichten Abschluss der Tür ermöglichten. Unter einem hinreichend luftdichten Abschluss ist dabei zu verstehen, dass das Austreten belasteter Luft aus dem Schwarzbereich in den Weißbereich in ausreichendem Maße verhindert wird. Je nach Anwendungsfall reicht hierfür bereits ein teilweiser Verschluss der Türöffnung aus, z. B. wenn ein Luftdurchtritt von dem Schwarzbereich in den Weißbereich durch eine Druckdifferenz zwischen den beiden Bereichen (z.B. Unterdruckhaltung, s.u.) und eine daraus resultierende erzwungene Luftströmung vom Schwarzbereich in den Weißbereich verhindert wird. Je nach dem Überlappungsgrad des Vorhangs mit der Wand und/oder dem Türrahmen ist es dabei möglich, dass der Vorhang an Wand und/oder Türrahmen angepresst wird, was zu einer besseren Abdichtung führt. In diesen Fällen kann der Vorhang auch in einer von Personen passierbaren Weise, beispielsweise durch sich überlappende Kunststoffbahnen, gestaltet sein; wird ein höherer Grad der Abdichtung bei gleichzeitiger Passierbarkeit gewünscht, ist beispielsweise die Verwendung luftdichter Reißverschlüsse möglich. Vorteilhafterweise kann zur Anbringung dieses Vorhangs eine entsprechende Aufnahme, beispielsweise ein Klettband, im Bereich des unteren Randes der Einrichtung vorgesehen sein.For foreclosure of a room, the device is clamped with closed air passage openings at the upper end of a door opening between the side rails of a door. On the device are preferably provided at its lower edge plastic films, plastic louvers or similar suitable elements, hereinafter referred to as a curtain, allowed a sufficiently airtight closure of the door. A sufficiently airtight closure is to be understood as meaning that the escape of contaminated air from the black area into the white area is prevented to a sufficient extent. Depending on the application, this is already sufficient for a partial closure of the door opening, z. B. if a Air passage from the black area in the white area by a pressure difference between the two areas (eg vacuum position, see below) and a resulting forced air flow from the black area is prevented in the white area. Depending on the degree of overlap of the curtain with the wall and / or the door frame, it is possible that the curtain is pressed against the wall and / or door frame, resulting in a better seal. In these cases, the curtain may also be designed in a manner passable by persons, for example by overlapping plastic sheets; if a higher degree of sealing is desired with simultaneous passability, for example, the use of airtight zippers is possible. Advantageously, a corresponding receptacle, for example a Velcro, may be provided in the region of the lower edge of the device for attaching this curtain.
Als Lüftereinheiten werden an dieser Stelle und im Folgenden Geräte zur Förderung von Luft jeglicher Bauweise betrachtet, die neben den für die Förderfunktion nötigen Elementen (zum Beispiel Ventilatoren) auch Einrichtungen zur Reinigung oder Filterung der Luft aufweisen können. Der Begriff Lüftereinheiten umfasst dabei auch Zusammenschaltungen luftfördernder und luftreinigender/-filternder Einrichtungen. Bei Bedarf größeren Luftvolumens können auch zwei oder mehr Lüftereinheiten verwendet werden, dabei kann eine entsprechende Anzahl Öffnungen der Einrichtung zur Durchführung von Schläuchen genutzt werden.As fan units are considered at this point and hereinafter devices for the promotion of air of any design, which may have in addition to the necessary elements for the promotion function (for example, fans) and facilities for cleaning or filtering the air. The term fan units also includes interconnections of air-conveying and air-cleaning / -filtering facilities. If required, larger volumes of air can also be two or more fan units are used, while a corresponding number of openings of the device can be used to pass hoses.
Die Einrichtung kann auch zur Unterdruckhaltung eines Raumes verwendet werden, wobei eine im Weißbereich oder im Schwarzbereich, vorzugsweise in ummittelbarer Nähe der Einrichtungaufgestellte Lüftereinheit über einen durch die Einrichtung geführten Schlauch mit dem anderen Bereich verbunden wird und so im Schwarzbereich den erforderlichen Unterdruck erzeugt. Dabei arbeitet die Lüftereinheit im Saugverfahren, falls die Lüftereinheit im Weißbereich steht, oder im Druckverfahren, falls die Lüftereinheit im Schwarzbereich steht.The device can also be used for maintaining the vacuum of a room, wherein a fan unit installed in the white area or in the black area, preferably in the immediate vicinity of the device, is connected to the other area via a hose guided through the device and thus generates the required negative pressure in the black area. The fan unit operates in the suction process, if the fan unit is in the white area, or in the printing process, if the fan unit is in the black area.
Ferner ist es möglich, zur Staubabsaugung ein oder zwei Lüftereinheiten im Schwarzbereich zu installieren und über Schläuche durch die Einrichtung hindurch mit dem Weißbereich zu verbinden. Die Schläuche können mit einem Stützensystem aufgeständert werden, um bei den Arbeiten nicht im Weg zu sein. Das System arbeitet in diesem Aufbau vorzugsweise im Druckverfahren, indem die Luft über die Filter gesaugt und durch die Einrichtung hindurch aus dem Schwarzbereich gefiltert in den Weißbereich gedrückt wird.Furthermore, it is possible to install one or two fan units in the black area for dust extraction and to connect them via hoses through the device to the white area. The hoses can be raised with a support system in order not to be in the way during the work. The system in this construction preferably operates in the printing process by sucking the air through the filters and filtering it through the device out of the black area into the white area.
Soll der Staub gezielt am Arbeitsplatz abgesaugt werden, so ist der Filterventilator direkt dort aufzustellen. Oft ist es jedoch nötig, die Staubabsaugung im gesamten oder einem wesentlichen Teil des Schwarzbereichs vorzunehmen. Hierfür kann die Absaugstelle, beispielsweise durch die Wahl des Aufstellungsortes der Lüftereinheit, so gewählt werden, dass sich der zur Staubabsaugung bestimmte Bereich zwischen Absaugstelle und Einrichtung befindet. Die Abschottung wird dabei so gewählt, dass ein gerichteter Luftzug, vorzugsweise von der Einrichtung bis zur Absaugstelle entsteht. Soll der ganze Raum des Schwarzbereichs abgesaugt werden, so wird die Absaugstelle vorzugsweise an der Stelle des Raumes mit dem größten Abstand zur Einrichtung gewählt. In allen Fällen ist es möglich und wird es erreicht, dass Frischluft durch die geöffnete Luftdurchtrittsöffnung der Einrichtung nachströmt.If the dust is to be specifically extracted at the workplace, the filter fan must be set up directly there. Often, however, it is necessary to perform the dust extraction throughout or a substantial portion of the black area. For this purpose, the extraction point, for example, by the choice of the installation site of the fan unit, be chosen so that the area dedicated to dust extraction between extraction point and device is located. The foreclosure is chosen so that a directed draft, preferably from the device to the extraction point. If the entire space of the black area to be sucked, the extraction point is preferably selected at the location of the room with the greatest distance to the device. In all cases, it is possible and it is achieved that fresh air flows through the open air passage opening of the device.
Ferner ist es möglich, die beschriebene Absaugung am Arbeitsplatz zu erreichen, indem der Filterventilator im Weissbereich aufgestellt wird, und über die Einrichtung mit dem Schwarzbereich über einen Schlauch verbunden ist, der am Arbeitsplatz endet bzw. dessen Öffnung direkt am Arbeitsplatz liegt. Das System arbeitet in diesem Aufbau vorzugsweise im Saugverfahren.Furthermore, it is possible to achieve the described extraction in the workplace by the filter fan is set up in the white area, and is connected via the device to the black area via a hose that ends at the workplace or its opening is directly at the workplace. The system works in this structure preferably in the suction process.
Ebenso ist es möglich, mit einer Lüftereinheit unbelastete Luft aus einem Weißbereich durch die Luftdurchtrittsöffnungen gezielt mittels Schlauch in einen definierten Bereich des Schwarzbereiches zu fördern. Das System arbeitet dann im Druckverfahren, falls der Filterventilator im Weissbereich aufgestellt ist, bzw. im Saugverfahren, falls der Filterventiltor im Schwarzbereich aufgestellt ist.Likewise, it is possible, with a fan unit, to convey unencumbered air from a white area through the air passage openings, specifically by means of a hose, into a defined area of the black area. The system then operates in the printing process if the filter fan is installed in the white area or in the suction process if the filter valve is installed in the black area.
