Description

Die Erfindung bezieht sich auf eine Tür oder eine Luke mit entsprechendem Stockrahmen welche für die Montage an Gehäusen für Klimageräte geeignet ist, wodurch der Zutritt ins Innere dieser Gehäuse, zwecks Inspektion und Wartung, insbesondere zwecks Einbringung von Filter oder anderer austauschbarer Teile der Klimageräte, ermöglicht wird, wobei für die Dimensionierung auch die Modularität der Struktur und/oder der Elemente welche das Gehäuse bilden berücksichtigt werden, ohne dass Anpassungsarbeiten erforderlich sind, um eine Montage, bzw. einen Austausch, auf einfache und schnelle Weise zu ermöglichen und eine wirkungsvolle Abdichtung ohne Wärmebrücken zu sichern.The invention relates to a door or a hatch with a corresponding floor frame which is suitable for mounting on housings for air conditioners, whereby access to the interior of these housing, for the purpose of inspection and maintenance, in particular for the introduction of filters or other replaceable parts of the air conditioners allows is taken into account, wherein for the dimensioning and the modularity of the structure and / or the elements which form the housing, without adjustment work being required to allow an assembly, or a replacement, in a simple and fast way and an effective seal without Secure thermal bridges.

Aus der EP 1813763 A2 ist die Herstellung von Türen und Luken bekannt welche aus einer äußeren und einer inneren Schale aus Metallblech geformt sind, unter sich durch Umbiegen der umlaufenden Ränder verbunden sind und einen vorstehenden mehrschichtigen umlaufenden Flansch bilden welcher dem, eventuell mit elastischer Dichtung versehenen, Anschlag am Stockrahmen entspricht, wobei dieser meist in einer Öffnung an einem der modularen Elemente, welche z.B. das Gehäuse für Klimageräte bilden, befestigt ist. Zwischen den besagten Schalen aus Metallblech ist ein wärmeisolierender Werkstoff enthalten, nachdem jedoch die äußere Schale mit der inneren im direkten Kontakt steht, findet zwischen dem äußeren Umfeld und dem Innenraum ein andauernder Temperaturaustausch an der gesamten umlaufenden Oberfläche statt, weiters sichert die einfache Dichtung nicht eine wirkungsvolle Abdichtung und, wegen des Fehlens einer Luftkammer und einer zweiten Dichtung, kommt es häufig zur Bildung von Kondenswasser im Bereich des Anschlags.From the EP 1813763 A2 the production of doors and hatches is known, which are formed from an outer and an inner shell made of sheet metal, are connected by bending over the peripheral edges and form a protruding multilayer circumferential flange which corresponds to the, possibly provided with elastic seal, stop on the floor frame This is usually in an opening on one of the modular elements, which form, for example, the housing for air conditioners attached. Between said metal sheet shells, a heat-insulating material is contained, but after the outer shell is in direct contact with the inner one, between the outer environment and the inner space continuous temperature exchange takes place on the entire circumferential surface, further the simple seal does not secure one Effective sealing and, due to the lack of an air chamber and a second seal, often leads to the formation of condensation in the area of the stop.

Es ist, z.B. aus der EP 2631407 A2 , der Einsatz metallischer Profile für die Herstellung von Türen oder Fenster und deren Stockrahmen bekannt, welche eine Wärmebrückenunterbrechung aufweisen, es ist weiters bekannt eine Luftkammer im Bereich des umlaufenden Anschlags vorzusehen welche durch zwei zueinander beabstandeter Dichtungen im Bereich des umlaufenden Anschlages des Flügels und des Stockrahmens definiert wird. Die Herstellung dieser Art von Verbundprofile ist relativ aufwändig und findet vorwiegend im Tür- und Fensterbau im Wohnungssektor Anwendung, wo ein häufiges Öffnen und Schließen und ein bestimmter Komfort gefragt ist.It is, for example, from the EP 2631407 A2 , the use of metallic profiles for the production of doors or windows and their floor frame known which have a thermal bridge break, it is also known to provide an air chamber in the region of the peripheral stop which by two spaced apart seals in the region of the peripheral stop of the wing and the frame is defined. The production of this type of composite profiles is relatively complex and is mainly in the door and window construction in the housing sector application where frequent opening and closing and a certain comfort is required.

Die obgenannten Lösungen sehen nicht das Realisieren des Stockrahmens mit einer möglichst großen vertikalen Durchgangslichte vor, nur an Balkon- oder Terrassentüren ist es bekannt eine möglichst flache Schwelle, von der in EP 1746240 A1 gezeigten Art, mit einem spezifischen Dichtungssystem zu verwenden, welches sich von jenem an den vertikalen Teilen und am oberen horizontalen Teil des Stockrahmens unterscheidet. Dieses spezifische Dichtungssystem macht von einer oder von zwei Bürstendichtungen Gebrauch, welche geeignet sind den Luftdurchzug zu begrenzen jedoch nicht um eine Abdichtung zu erreichen.The above solutions do not provide the realization of the floor frame with the largest possible vertical passage light, only on balcony or patio doors, it is known a very shallow threshold, from the in EP 1746240 A1 shown to use with a specific sealing system, which differs from that of the vertical parts and the upper horizontal part of the floor frame. This specific sealing system makes use of one or two brush seals which are suitable for limiting the passage of air but not for achieving a seal.

Die Erfindung stellt sich die Aufgabe eine Tür oder eine Luke der obgenannten Art für Gehäuse für Klimageräte zu schaffen, wobei eine maximale vertikale Durchgangslichte gesichert wird welche fast der maximalen vertikalen Höhe der Tür oder der Luke entspricht, wobei eine Abdichtung zwischen dem Türflügel und dem Türstock und eine Wärmedämmung ohne Wärmebrücken zwischen dem Außenteil welcher normalerweise den Umwelteinflüssen ausgesetzt ist und dem Innenteil welcher den im Gehäuseinneren herrschenden Temperatur- und Feuchtigkeitsverhältnissen ausgesetzt ist, gesichert wird, wodurch die Kondensbildung, insbesondere im Bereich zwischen Stockrahmen und Türflügel, verhindert wird.The invention has as its object to provide a door or hatch of the type mentioned above for housing for air conditioning units, wherein a maximum vertical passage light is secured which almost corresponds to the maximum vertical height of the door or the hatch, with a seal between the door leaf and the door frame and a thermal insulation without thermal bridges between the outer part which is normally exposed to the environmental influences and the inner part which is exposed to the inside of the housing temperature and humidity conditions, is secured, whereby the condensation, especially in the area between the floor frame and door is prevented.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Tür vor welche aus einer äußeren und einer inneren Blechschale besteht, welche beide einen umlaufenden um 90° abgebogenen Rand aufweisen welcher an einem zwischenliegenden Kunststoffprofil mit mehreren Innenkammern befestigt ist, wobei dieses als Wärmebrückenunterbrechung wirkt. Der Raum zwischen den besagten Schalen welcher leicht zugänglich ist, kann mit wärmeisolierendem Werkstoff ausgefüllt werden. Das besagte Kunststoffprofil weist einen Sitz für den Einsatz einer ersten elastischen Dichtung und, in einem dazu beabstandeten Bereich, für eine zweite elastische, z,B. anextrudierte, Dichtung, auf. Der Querschnitt durch den Umfangsbereich der Tür ist also identisch für die vertikalen und auch für beide horizontalen Seiten.To solve this problem, the invention proposes a door which consists of an outer and an inner sheet metal shell, both of which have a circumferential bent by 90 ° edge which is attached to an intermediate plastic profile with a plurality of inner chambers, which acts as a thermal bridge interruption. The space between said shells, which is easily accessible, can be filled with heat-insulating material. Said plastic profile has a seat for the use of a first elastic seal and, in a spaced-apart area, for a second elastic, z, B. extruded, seal, on. The cross section through the peripheral area of the door is therefore identical for the vertical and also for both horizontal sides.

Der Stockrahmen für die besagte Tür besteht aus zwei vertikalen Teilen, von denen jedes der Teile aus einem metallischen Verbundprofil mit zwischengelegten Kunstsoffstegen von der bekannten Art, zwecks Wärmebrückenunterbrechung, zwischen dem äußeren Teil welcher den Umwelteinflüssen ausgesetzt ist und dem inneren Teil welcher den Temperatur- und Feuchtigkeitsverhältnissen im Gehäuseinneren ausgesetzt ist und aus zwei identischen horizontalen Elementen welche aus L-förmig gebogenem Blech oder aus einem L-Profil mit flachem Querschnitt hergestellt sind, wobei der vertikale Flansch an der, dem Gehäuseinneren zugewandten Seite, als Anschlag für die erste der, am Turanschlag umlaufend montierten, Dichtungen dient. Die besagten horizontalen Elemente sind an beiden der Enden mittels Schrauben an den Stirnflächen der entsprechenden vertikalen Verbundprofile befestigt, welche zu diesem Zweck mit eigenen Einschraubsitzen mit vertikalen Achsen ausgestattet sind.The floor frame for the said door consists of two vertical parts, of which each of the parts of a composite metal profile with interposed Kunstsoffstegen of the known type, for thermal bridge interruption, between the outer part which is exposed to the environmental influences and the inner part of which the temperature and Moisture conditions inside the housing is exposed and made of two identical horizontal elements which are made of L-shaped bent sheet metal or of an L-shaped profile with a flat cross-section, wherein the vertical flange on the, the inside of the housing facing side, as a stop for the first, on Turanschlag peripherally mounted, seals used. Said horizontal elements are fixed at both ends by means of screws to the end faces of the corresponding vertical composite profiles, which are equipped for this purpose with their own screw-in vertical axis.

Um eine wirkungsvolle Abdichtung mittels der ersten Dichtung, welche an der Tür im Umfangsbereich umlaufend angebracht und gegen das Gehäuseinnere ausgerichtet ist, sei es an den vertikalen Verbundprofilen des Türstockes als auch an den im Querschnitt L-förmigen horizontalen Elementen, zu sichern, weist die besagte Dichtung vorzugsweise einen rohr- oder pilzförmigen Querschnitt auf.In order to secure an effective seal by means of the first seal, which is circumferentially mounted on the door circumferentially and aligned against the housing interior, be it to secure the vertical composite profiles of the door frame as well as the cross-sectionally L-shaped horizontal elements, the said Seal preferably a tubular or mushroom-shaped cross section.

Die Dichtung liegt, bei geschlossenem Türflügel, infolge einer elastischen Verformung durch Druckbelastung, entlang einer der sich gegenüberliegenden Seiten an der abgebogenen Flanke der inneren Schale der Tür und, entlang der anderen Seite, am Bereich der, zum Gehäuseinneren ausgerichteten, Kante des vertikalen Verbundprofils, an. In Bezug auf die beiden horizontalen, im Querschnitt L-förmigen, Elemente hingegen liegt die selbe erste Dichtung, entlang einer Seite immer am abgebogenen Rand der inneren Schale des Türflügels an, während sie, mit einem Teil der nach innen des Gehäuses für Klimageräte gewandten Fläche, an jenem Anschlag anliegt, welcher vom vertikalen Flansch der L-förmig gebogenen oder im Querschnitt L-förmigen Profile gebildet wird. Die besagten Elemente mit L-förmigem Querschnitt können vorteilhafterweise, z.B. durch Biegen eines Inox-Bleches hergestellt werden, ohne den Einsatz profilierter oder extrudierter Elemente aus unterschiedlichen Werkstoffen auszuschließen. Um die Wärmeübertragung zwischen dem, dem Gehäuseinneren und dem Gehäuseaußenbereich ausgesetzten Teilen zu reduzieren, kann der breite Teil des L-förmigen Profils schmäler als die Breite der vertikalen Elemente des Türstocks sein oder Längsschlitze oder Ausnehmungen aufweisen um den Querschnitt für die Wärmeübertragung, insbesondere im nach außen gerichteten Bereich, jenseits des Auflagebereiches der koextrudierten Dichtung am, die beiden Schalen des Türflügels verbindenden, Kunststoffprofil zu reduzieren. Im Falle des schmäleren Flansches kann, im Bereich der Befestigung an der Stirnfläche der vertikalen Elemente, ein Element aus wärmeisolierendem Kunststoff vorgesehen sein welches den, nicht vom Flansch des L-förmigen Elementes abgedeckten, Bereich einnimmt.The seal is, with the door closed, due to an elastic deformation by compression, along one of the opposite sides of the bent edge of the inner shell of the door and, along the other side, at the area of the housing interior oriented edge of the vertical composite profile, on. On the other hand, with respect to the two horizontal elements, which are L-shaped in cross-section, the same first gasket, along one side always bears against the bent edge of the inner shell of the door leaf, while with part of the surface facing the inside of the air conditioner housing , abuts that stop which is formed by the vertical flange of the L-shaped or in cross-section L-shaped profiles. The said L-shaped cross-section elements may advantageously be made e.g. by bending an Inox sheet without precluding the use of profiled or extruded elements made of different materials. In order to reduce the heat transfer between the, the housing interior and the housing outer portion exposed parts, the broad part of the L-shaped profile may be narrower than the width of the vertical elements of the door block or longitudinal slots or recesses have around the cross section for heat transfer, in particular in outside directed area, beyond the contact area of the coextruded seal on, the two shells of the door connecting, reducing plastic profile. In the case of the narrower flange may be provided in the region of the attachment to the end face of the vertical elements, an element made of heat-insulating plastic which occupies the area not covered by the flange of the L-shaped element.

Um die progressive und wirksame Verformung der ersten Dichtung welche umlaufend am Türflügel, entlang dem nach innen des Gehäuses für Klimageräte ausgerichteten Rand angebracht ist, zu begünstigen, hat das vertikale Verbundprofil des Stockrahmens einen keilförmigen Querschnitt welcher die freie Durchgangslichte in Richtung Gehäuseinneres vermindert.In order to promote the progressive and effective deformation of the first seal circumferentially on the door, along the inside of the housing for air conditioning aligned edge, the vertical composite profile of the floor frame has a wedge-shaped cross-section which reduces the free passage light towards the housing interior.

Die Praxis, hat gezeigt, dass die Tür, bzw. die Luke, mit den erfindungsgemäßen Konstruktionsmerkmalen auch den, durch die Druckänderungen zwischen dem Gehäuseinneren und dem Außenbereich hervorgerufenen, Belastungen gut standhält, wobei sie die Formstabilität und die Dichtheit sicherstellt.Practice has shown that the door, or hatch, with the design features of the present invention will also withstand the stresses caused by the pressure changes between the housing interior and the exterior, while ensuring dimensional stability and tightness.

Die Anbringung der Scharniere und Klinken, bzw. der Verschlussbeschläge, an der Tür erfolgt auf bekannte Art.
Die Befestigung des Türstockes an den modularen Elementen und/oder an der Struktur des Gehäuses für Klimageräte erfolgt mittels bekannter Befestigungselemente, wobei zu berücksichtigen ist dass, wegen des flachen Querschnittes die L-förmigen horizontalen Elemente mehrere Befestigungspunkte erforderlich sind um dadurch diesen Elementen mehr Formstabilität zu verleihen.The attachment of the hinges and pawls, or the fastener fittings, on the door in a known manner.
The attachment of the door frame to the modular elements and / or on the structure of the housing for air conditioners by means of known fasteners, bearing in mind that, because of the flat cross-section, the L-shaped horizontal elements several attachment points are required to thereby these elements more dimensional stability to lend.

The directed towards the inside of the housing for air conditioners shell 1 a has a peripheral edge 1 b on which angled at 90 ° and, for. by gluing, anchored in a groove 2a of the plastic profile 2. Also, the outer shell 1c has a circumferential edge 1d angled by 90 ° on which is fastened by means of screws 3 on the same plastic profile 2, this shell is thus light. also subsequently, removable, e.g. to replace the heat-insulating material between the two shells.

Das Kunststoffprofil 2 ist von der extrudierten Art mit mehreren Innenkammern um eine hohe Formstabilität zu sichern und als Unterbrechung der Wärmeübertragung zwischen den beiden Schalen 1a, 1 c zu wirken, welche unterschiedlichen Temperaturen ausgesetzt sind. In eine Rille 2b des Profils 2 ist eine elastische Dichtung 4 eingesetzt, diese ist von der rohrförmigen Art und liegt mit einer Längsseite am Rand 1 b der inneren Schale 1 a an. An der Längsseite des Profils 2 welche zum Türstock 6, 8 gerichtet ist, ist eine anextrudierte elastische, in Richtung Türstock abragende, Dichtung 2c vorgesehen. Die Erfindung schließt nicht aus, dass auch die Dichtung 4 von der anextrudierten Art ist.The plastic profile 2 is of the extruded type with several inner chambers to ensure a high dimensional stability and to act as an interruption of heat transfer between the two shells 1 a, 1 c, which are exposed to different temperatures. In a groove 2b of the profile 2, an elastic seal 4 is inserted, this is of the tubular type and is located with a longitudinal side at the edge 1 b of the inner shell 1 a. On the longitudinal side of the profile 2 which is directed to the door frame 6, 8, an anextruded elastic, projecting towards the door frame, seal 2c is provided. The invention does not exclude that also the seal 4 is of the anextruded type.

Der erfindungsgemäße Türstock besteht aus zwei vertikalen Verbundprofilen 6 mit Elementen 6a für die Unterbrechung der Wärmebrücken und aus zwei im Querschnitt L-förmigen horizontalen Elementen 8 welche an den Enden mittels Schrauben 3 an den oberen und unteren Stirnflächen der vertikalen Verbundprofile 6 befestigt sind welche für diesen Zweck mit Einschraubsitze 6d versehen sind. Die besagten horizontalen L-förmigen Elemente 8 weisen auf der nach innen des Gehäuses für Klimageräte gerichteten Seite einen vertikalen Flansch 8a auf welcher als Anschlag für die Dichtung 4 des Türflügels 1 wirkt, während an der nach außen gerichteten Seite, vorzugsweise in einem Bereich jenseits der Auflage der Dichtung 2c des Profils 2, der Querschnitt durch Durchbrüche oder Längsschlitze 8b reduziert ist. Sei es die horizontalen L-förmigen Elemente 8, als auch die vertikalen Profile 6, sind am Gehäuse für Klimageräte mittels Schrauben 7 oder anderer bekannter Befestigungsmittel befestigt. Die vertikalen Profile 6 haben einen keilförmigen Querschnitt mit dem breiteren Teil nach innen des Gehäuses für Klimageräte gerichtet um, während dem letzten Teil der Schließbewegung der Tür 1, die elastische Verformung der Dichtung 4 durch Druckbelastung zwischen dem Bereich nahe an der Kante der Verbundprofile 6 und dem Rand 1 a der inneren Schale, zu bewirken. Während der selben Schließbewegung wird hingegen die Dichtung 4 mit der Stirnlängsseite gegen den, als Anschlag wirkenden, Flansch 8a der horizontalen L-förmigen Elemente 8 gedrückt.The door frame according to the invention consists of two vertical composite profiles 6 with elements 6a for the interruption of the thermal bridges and two cross-sectionally L-shaped horizontal elements 8 which are fastened at the ends by means of screws 3 to the upper and lower faces of the vertical composite profiles 6 which for this Purpose are provided with screw-in 6d. The said horizontal L-shaped elements 8 point to the inside the housing for air conditioners directed side a vertical flange 8a on which acts as a stop for the seal 4 of the door leaf 1, while on the outward side, preferably in an area beyond the support of the seal 2c of the profile 2, the cross section through Breakthroughs or longitudinal slots 8b is reduced. Be it the horizontal L-shaped elements 8, as well as the vertical profiles 6, are attached to the housing for air conditioners by means of screws 7 or other known fastening means. The vertical profiles 6 have a wedge-shaped cross section with the wider part directed inwards of the housing for air conditioning units, during the last part of the closing movement of the door 1, the elastic deformation of the gasket 4 by compressive loading between the area close to the edge of the composite profiles 6 and the edge 1 a of the inner shell to effect. During the same closing movement, however, the seal 4 is pressed with the front longitudinal side against the, acting as a stop, flange 8a of the horizontal L-shaped elements 8.

Zwischen der Dichtung 4 und der koextrudierten, vom Profil 2 abstehenden, Dichtung 2c bildet sich, bei geschlossener Tür 1, eine dichte Luftkammer A welche geeignet ist die isolierende Wirkung zwischen jenem Teil welcher dem Inneren des Gehäuses für Klimageräte ausgesetzt ist und jenem welcher den eventuellen Umwelteinflüssen ausgesetzt ist, zu verbessern.Between the seal 4 and the co-extruded, protruding from the profile 2, seal 2c is formed, with the door closed 1, a dense air chamber A which is suitable for the insulating effect between that part which is exposed to the interior of the housing for air conditioners and that which the eventual Environment is exposed to improve.
