Description

Die Erfindung betrifft ein Einbauelement für Öffnungen in der Außenwand eines Gebäudes, insbesondere einer elektrischen Umspann- oder Schaltstation, mit in einem Rahmen oder Gehäuse vorgesehenen Schwenkklappen zum Abdecken eines offenen Lüftungsquerschnittes, wobei sich parallel übereinander in einer vertikalen Fluchtlinie zwischen Seitenwangen des Rahmens oder Gehäuses sowie außermittig dieser Seitenwangen Achsstifte od. dgl. Achselemente für die Schwenkklappen erstrecken.The invention relates to a built-in element for openings in the outer wall of a building, in particular an electrical transformer or switching station, with swivel flaps provided in a frame or housing for covering an open ventilation cross-section, parallel to one another in a vertical line of alignment between side walls of the frame or housing and Extend the center pins or the like of these side cheeks. Axle elements for the swivel flaps.

Zum Entlüften von Räumen sind derartige Einbauelemente bekannt, dies sowohl mit einer einzigen Klappe als auch mit mehreren Lamellen, welche in geschlossenem Zustand des Lüftungselementes schuppenartig aufeinanderliegen und den Lüftungsquerschnitt schließen.Installation elements of this type are known for venting rooms, both with a single flap and with a plurality of lamellae, which in the closed state of the ventilation element lie on one another in a scale-like manner and close the ventilation cross section.

So offenbart die Schrift zum DE-GM 92 10 666 der Anmelderin beispielsweise ein gattungsgemäßes Einbauelement mit an den Achsstiften aufgehängten Profilen gewellten Querschnittes, deren freie Enden in Schließstellung dem benachbarten Profil anliegen und in Öffnungsstellung in Abstand zueinander an einen vertikalen Anschlagstreifen stoßen.Thus, the document to DE-GM 92 10 666 by the applicant discloses, for example, a generic built-in element with corrugated cross-sections suspended from the axle pins, the free ends of which abut the adjacent profile in the closed position and abut a vertical stop strip at a distance from one another in the open position.

In Kenntnis dieses Standes der Technik hat sich der Erfinder das Ziel gesetzt, ein Einbauelement der eingangs erwähnten Art mit Schwenkklappen weitergehend zu verbessern sowie dessen Einsatzgebiet zu erweitern und die Lagerhaltung zu verringern.Knowing this state of the art, the inventor has set itself the goal of further improving a built-in element of the type mentioned at the outset with pivoting flaps, of expanding its area of use and of reducing the stock-keeping.

Zur Lösung dieser Aufgabe führt die Lehre des unabhängigen Anspruches. Die Unteransprüche erfassen vorteilhafte Weiterbildungen.The teaching of the independent claim leads to the solution of this task. The subclaims cover advantageous further developments.

Erfindungsgemäß bestehen die Schwenkklappen jeweils aus einem Klappenkörper als Gewicht oder Kraftspeicher und einer daraus abragenden Flügelleiste; im Bereich des Klappenkörpers verläuft ein Lagerkanal für den Achsstift, und die vom Klappenkörper ausgehende Flügelleiste ist nahe des Lagerkanals vom Klappenkörper in einem Winkel zum Lagerkanal hin geneigt. Zudem soll der Klappenkörper als Kraftspeicher exzentrisch gelagert und durch Druck auf seine Flügelleiste um den Achsstift drehbar sein.According to the invention, the swivel flaps each consist of a flap body as a weight or energy store and a wing strip projecting therefrom; A bearing channel for the axle pin runs in the area of the valve body, and the wing ledge extending from the valve body is inclined at an angle to the bearing channel near the bearing channel from the valve body. In addition, the valve body should be mounted eccentrically as an energy store and be rotatable about the axis pin by pressure on its wing bar.

In einer Einbaulage verläuft die Flügelleiste oberhalb des Klappenkörpers, und die Schwenkklappe ist in Öffnungsstellung aktiv gelagert. Diese begünstigt den Einbau zur Druckentlastung; im Gebäudeinnenraum entstehender Überdruck drückt die Schwenkklappen aus ihrer passiven Ruhelage, der Schließstellung, in die Öffnungsposition, in der die Rückstellkraft in beschriebener Weise gespeichert wird.In an installed position, the wing strip runs above the flap body and the swivel flap is actively supported in the open position. This favors installation for pressure relief; Overpressure arising in the building interior pushes the swing flaps out of their passive rest position, the closed position, into the open position, in which the restoring force is stored in the manner described.

Im zweiten Falle verlaufen die Flügelleisten in Einbaulage unterhalb des Klappenkörpers, und die Schwenkklappen sind in Schließstellung aktiv gelagert. Diese Art des Einbaues wird bei einem Druckverschluß bevorzugt; herrschen im Gebäude und außerhalb gleiche Drücke, ruhen die Schwenkklappen in hängender Schließstellung, aus der sie - Kraft speichernd - - durch einen einziehenden Luftstrom ausgeschwenkt werden können.In the second case, the wing strips run below the flap body in the installed position, and the swivel flaps are actively supported in the closed position. This type of installation is preferred for a pressure lock; If there are the same pressures in the building and outside, the swing flaps rest in the hanging closed position, from which they can be swung out by a retracting air flow - storing energy.

Nach einem weiteren Merkmal der Erfindung soll der Klappenkörper querschnittlich etwa rechteckförmig sowie an einer Schmalseite nahe einer Unterfläche mit einem Teilkreisansatz für den Lagerkanal versehen sein, dem an der anderen Ecke der Schmalseite die geneigte Flügelleiste gegenüberliegt.According to a further feature of the invention, the flap body should be approximately rectangular in cross section and provided on one narrow side near a lower surface with a pitch circle for the bearing channel, which is opposite the inclined wing strip on the other corner of the narrow side.

Dank dieser Maßgaben wird eine Schwenkklappe angeboten, die in einem sog. Aktivzustand eine Kraft speichert, welche beim Nachlassen der äußeren Schwenkkraft eines Luftdruckes zur Rückstellung der Schwenkklappen dient.Thanks to these provisions, a swivel flap is offered that stores a force in a so-called active state, which serves to reset the swivel flaps when the external swivel force of an air pressure decreases.

Nach einem weiteren Merkmal der Erfindung ist in eine Unterfläche des Klappenkörpers wenigstens eine Nut für eine Dichtlippe eingebracht, die in Schließstellung die Dichtigkeit des Einbauelementes gewährleistet. Die Besonderheit der erfindungsgemäßen Konstruktion ist es, daß sie in zwei unterschiedlichen Einbaulagen für ebenso verschiedene Zwecke eingesetzt zu werden vermag.According to a further feature of the invention, at least one groove for a sealing lip is introduced into a lower surface of the valve body, which ensures the tightness of the installation element in the closed position. The special feature of the construction according to the invention is that it can be used in two different installation positions for equally different purposes.

Als günstig hat es sich erwiesen, daß eine Rückenfläche des Klappenkörpers mit der Flügelleiste ein Winkel von mehr als 110° -- bevorzugt etwa 135° -- bestimmt.It has proven to be favorable that a back surface of the flap body with the wing bar determines an angle of more than 110 ° - preferably about 135 °.

In Schließstellung der Schwenkklappen sollen deren Dichtlippen an eine durch die Achsquerschnitte gelegten Fluchtlinie jeweils die Flügelleiste der benachbarten Schwenkklappe berühren, wobei eine dem Rahmen benachbarte Dichtlippe des endwärtigen Klappenkörpers einer Anschlagleiste des Rahmens anliegt.In the closed position of the swivel flaps, their sealing lips should touch the wing strip of the adjacent swivel flap on an alignment line through the axial cross sections, a sealing lip of the end flap body adjacent to the frame abutting a stop strip of the frame.

In Öffnungsstellung des Einbauelementes sollen die Flügel-leisten der Schwenkkörper in Abstand zur benachbarten Schwenkklappe stehen, wobei der querschnittlich etwa rechteckige Klappenkörper etwa horizontal von der der Flügelleiste abgekehrten Seite der Schwenkachse abragt, um eine ausreichende Rückstellkraft speichern zu können. Zudem kann bei einem erfindungsgemäßen Einbauelement mit einem endwärtigen Winkelarm der Schwenkklappe die Flügelleiste einen etwa parallel zur Rückenfläche des Klappenkörpers verlaufenden Winkelarm aufweisen, der in offenem Zustand als Anschlag dient und sich in geschlossenem Zustand an die benachbarte Dichtlippe schmiegt.In the open position of the installation element, the wing strips of the swivel body should be at a distance from the adjacent swivel flap, with the flap body, which is approximately rectangular in cross section, projecting approximately horizontally from the side of the swivel axis facing away from the wing strip, in order to be able to store a sufficient restoring force. In addition, in a built-in element according to the invention with an end angle arm of the swivel flap, the wing strip can have an angle arm running approximately parallel to the back surface of the flap body, which serves as a stop in the open state and nestles against the adjacent sealing lip in the closed state.

Bei einem Einbauelement, für welches gesondert Schutz begehrt wird, dient vorteilhafterweise als Anschlag für die Schwenkklappe eine Profilrinne des Einbauelementes, welche beidseits eines mittleren Wandabschnittes jeweils einen aufwärts gewinkelten Wandabschnitt aufweist; zumindest der der Schwenkklappe nahe Winkel entspricht hier dem Winkel zwischen Flügelleiste und Winkelarm. Zudem soll hier die Profilrinne zwei gegenläufig gerichtete Schlitze zur Aufnahme der Längskanten von Lochblechen od. dgl. Platten besitzen, wobei diese Schlitze etwa parallel zueinander sowie zur Schwenkklappe in deren Schließstellung verlaufen.In the case of a built-in element for which protection is sought, a profile groove of the built-in element advantageously serves as a stop for the pivoting flap, which has an upwardly angled wall section on both sides of a central wall section; at least the angle close to the swivel flap corresponds here to the angle between the wing bar and angle arm. In addition, the profile trough here should have two oppositely directed slots for receiving the longitudinal edges of perforated sheets or the like, wherein these slots run approximately parallel to one another and to the swivel flap in its closed position.

The horizontal distance f of the axis rods 16 from the right cheek edge 15 in FIG. 1, 2 measures 24 mm, and is therefore shorter than the distance to the other cheek edge 15 a .

Sowohl von der Bodenplatte 12 als auch von der Firstplatte 13 ragt jeweils eine querschnittlich dreiecksförmige Anschlagleiste 20 ab, wobei die Spitze der unteren Anschlagleiste 20 in die Fluchtlinie Q der Achsstäbe 18 fällt und die obere Anschlagleiste 20 aus dieser etwas zur rechten Wangenkante 20 versetzt ist. Letztere ist zum Gebäudeinnenraum hin gerichtet, also zur Druckseite.A cross-sectionally triangular stop bar 20 protrudes from both the base plate 12 and the ridge plate 13, the tip of the lower stop bar 20 falling into the alignment line Q of the axle rods 18 and the upper stop bar 20 being slightly offset from this to the right cheek edge 20. The latter is directed towards the interior of the building, i.e. towards the pressure side.

Die Schwenkklappe 18 ist bevorzugt von einem Strangpreßprofil abgelängt und besteht gemäß Fig. 5 aus einem Klappenkörper 22 mit - - einen angeformten Teilkreisansatz 24 durchsetzendem - - Lagerkanal 25 für einen der Achsstifte 16 sowie mit einer an den Klappenkörper 32 ebenfalls angeformten Flügelleiste 26. Der Querschnitt des Klappenkörpers 22 ist Teil eines Konstruktionsrechteckes K einer Länge n von 23 mm und einer Höhe i von 14 mm. Die der Schmalseite 23 mit dem Lagerkanal 25 entferntliegende andere Seite 28 des Klappenkörpers 22 ist in einem Winkel w von etwa 45° zur entsprechenden Seite des Konstruktionsrecktecks K abgeschrägt und bildet mit einer gegenläufigen Schräge 29 einen Heck- oder Profilwinkel t. Mit der von jener Seite 28 des Klappenkörpers 22 ausgehenden Rückenfläche 30 schließt die Flügelleiste 26 einen Winkel q von 135° ein und endet mit einem zu ihr vom Klappenkörper 22 weg geneigten Winkelarm 27 - die Gesamtlänge e dieser Flügelleiste 26,27 beträgt vom Lagerkanalmittelpunkt weg etwa 50 mm.The pivoting flap 18 is preferably cut to length from an extruded profile and, as shown in FIG. 5, consists of a flap body 22 with a bearing channel 25 for one of the axle pins 16 and an integrally formed part-circle projection 24 and a wing strip 26 which is also integrally formed on the flap body 32 the valve body 22 is part of a construction rectangle K of a length n of 23 mm and a height i of 14 mm. The other side 28 of the flap body 22, which is remote from the narrow side 23 with the bearing channel 25, is chamfered at an angle w of approximately 45 ° to the corresponding side of the construction corner triangle K and forms a rear or profile angle t with an opposing bevel 29. With the back surface 30 extending from that side 28 of the flap body 22, the wing strip 26 encloses an angle q of 135 ° and ends with an angle arm 27 inclined toward it from the flap body 22 - the total length e of this wing strip 26, 27 is approximately from the center of the bearing channel 50 mm.

Dank der beschriebenen Ausgestaltung der Schwenkklappen 18 verschließen diese dabei in passiver Hängestellung nach Fig. 2 bei vertikal aufragender Flügelleiste 26 die Öffnung des Einbauelementes 10; die Seite 28 des Klappenkörpers 22 verläuft dabei parallel zur Wangenkante 15, und der Winkelschenkel 27 liegt der Dichtlippe 36 - - bzw. bei der obersten Schwenkklappe 18 der Anschlagleiste 20 -- an. Gleichzeitig berüht die untere Dichtlippe 36 die untere Anschlagleiste 20.1 to 4, the inside of the print or building is to be presented on the right, and the outside of the building is then on the left of the figure. 1, 2 show the swivel flaps 18 as pressure relief flaps. Thanks to the described design of the swivel flaps 18, they close the opening in the passive hanging position according to FIG. 2 with the wing bar 26 projecting vertically the built-in element 10; the side 28 of the flap body 22 runs parallel to the cheek edge 15, and the angled leg 27 lies against the sealing lip 36 - or at the uppermost swivel flap 18 of the stop bar 20 -. At the same time, the lower sealing lip 36 contacts the lower stop bar 20.

Zur Druckentlastung des Innenraumes werden die Schwenkklappen 18 gegen den Uhrzeigersinn in den in Fig. 1 wiedergegebenen Aktivzustand gedreht, d. h. der ausziehende Luftstrom hält die Schwenkklappe 18 gegen das Gewicht ihres Klappenkörpers 22 in Öffnungsstellung.To relieve the pressure in the interior, the swivel flaps 18 are rotated counterclockwise into the active state shown in FIG. H. the exhausting air flow holds the swing flap 18 against the weight of its flap body 22 in the open position.

Eine Endleiste an der Außenkante 15a der Seitenwange 14 kann als stabiliserende Anschlagfläche für die Winkelarme 27 dienen.An end bar on the outer edge 15 a of the side wall 14 can serve as a stabilizing stop surface for the angle arms 27.

Beim Ausführungsbeispiel der Fig. 3,4 sind die beschriebenen Schwenkklappen 18 als Druckverschluß mit nach unten hängender Flügelleiste 26 eingebaut und befinden sich in der Öffnungsstellung nach Fig. 3 zum Einzug von Zuluft in den Innenraum des Gebäudes in Durchzugstellung, wobei gegebenenfalls die Winkelarme 27 der Flügelleiste 26 eine entlang der Innenkante 15 verlaufende Anschlagfläche berühren.In the embodiment of Fig. 3,4, the pivoting flaps 18 described are installed as a pressure lock with the wing strip 26 hanging downward and are in the open position according to FIG. 3 for the intake of supply air into the interior of the building in the pull-through position, with the angle arms 27 possibly Wing bar 26 touch a stop surface running along the inner edge 15.

Bei Unterbrechung des Luftzustroms drehen die Schwenkklappen 18 im Uhrzeigersinn in einen Aktivzustand nach Fig. 4; die Schwenkklappen 18 werden durch den Innendruck in Verschlußposition gehalten, in welche der Klappenkörper 22 trachtet, seine Flügelleiste 26 zur Innenkante 15 hin zu führen.If the air flow is interrupted, the swivel flaps 18 turn clockwise into an active state according to FIG. 4; the swivel flaps 18 are held in the closed position by the internal pressure into which the flap body 22 seeks to guide its wing strip 26 toward the inner edge 15.

Die Figurenpaare 1,2 und 3,4 lassen deutlich werden, daß es sich um eine Ausführung der Einbauelemente 10 handelt, das im Falle der Fig. 3,4 um 180° gegenüber Fig. 1,2 gedreht eingebaut worden ist.The pairs of figures 1, 2 and 3, 4 make it clear that this is an embodiment of the installation elements 10, which in the case of FIG. 3, 4 has been installed rotated by 180 ° with respect to FIG.

Die Ausführung der Fig. 6 läßt erkennen, daß die Seite 28 des Klappenkörpers 22 dessen maximalen Schwenkradius r angepaßt, also querschnittlich teilkreisförmig, ist. Der Schwenkradius r mißt dabei etwas weniger als der Abstand f der Fluchtlinie Q von der benachbarten Innenkante 15.The embodiment of FIG. 6 reveals that the side 28 of the flap body 22 is adapted to its maximum swivel radius r, that is to say it is partially circular in cross section. The swivel radius r measures slightly less than the distance f of the alignment line Q from the adjacent inner edge 15.

In einem Einbauelement 40 anderer Ausgestaltung sind nach Fig. 7,8 Schwenkklappen 42 mit querschnittlich gerundeten Klappenkörpern 22 nahezu unmittelbar an der einen Wangenkante 15 in Abschnitt f₁ angelenkt. Sie schlagen in Öffnungsstellung -- Fig. 8 -- jeweils gegen einen rinnenförmigen Einsatz 44 aus drei zueinander gewinkelten Wandabschnitten 45,45a,45b; das frontwärtige Ende des Wandabschnittes 45b endet als vertikaler Anschlagwinkel 46. Der mittlere Wandabschnitt 45 ist einends mit einem nach oben weisenden Kederprofil 47 ausgestattet und andernends mit zwei zueinander gegenläufigen Vertikalschlitzen 48 zum Einschieben eines Lochbleches 50 als Stochersicherung. Zudem finden sich dort Tropflöcher 49.In a built-in element 40 of another design, FIG. 7,8 swivel flaps 42 with flap bodies 22 that are rounded in cross section are hinged almost directly to one cheek edge 15 in section f 1. They strike in the open position - FIG. 8 - each against a trough-shaped insert 44 made of three wall sections 45, 45 a , 45 b angled to one another; the front end of the wall section 45 b ends as a vertical stop bracket 46. The middle wall section 45 is equipped at one end with an upward-facing piping profile 47 and at the other end with two mutually opposite vertical slots 48 for inserting a perforated plate 50 as a pocketing device. There are also drip holes 49 there.
