Description

Die Erfindung betrifft eine Klappe, insbesondere Drosselklappe, zur Beeinflussung eines in einer raumluft- und klimatechnischen Anlage strömenden Volumenstroms.The invention relates to a flap, in particular throttle valve, for influencing a flowing in a room air and air conditioning plant volume flow.

Aus der Praxis sind Drosselklappen aus Blech bekannt, die mittels einer separaten Welle oder Achse in einem Lüftungskanal einer raumluft- und klimatechnischen Anlage montiert werden, so dass sie drehbar gelagert sind. Nachteilig hierbei ist, dass derartige Klappen konstruktiv aufgrund der Bauteilanzahl aufwendig sind und auch der Zusammenbau und die Montage entsprechend zeitintensiv ist. Die US-PS 5,806,830 offenbart einen Plastik-Abziehanschluss für Zuluftleitungen.From practice throttle valves made of sheet metal are known, which are mounted by means of a separate shaft or axle in a ventilation duct of a ventilation and air conditioning system, so that they are rotatably mounted. The disadvantage here is that such flaps are structurally complex due to the number of components and also the assembly and assembly is correspondingly time-consuming. The U.S. Patent 5,806,830 discloses a plastic extraction port for air supply lines.

Aufgabe der Erfindung ist es, die vorgenannten Nachteile zu vermeiden und eine Klappe anzugeben, die konstruktiv einfacher ausgestaltet und zudem einfacher herstellbar und auch montierbar ist.The object of the invention is to avoid the aforementioned disadvantages and to provide a flap which is designed structurally simpler and also easier to manufacture and mount.

Diese Aufgabe wird dadurch gelöst, dass die Klappe in einem eine Öffnung aufweisenden Einbaurahmen angeordnet ist und dass die Klappe und der Einbaurahmen eine Montageeinheit bilden, wobei die Klappe verschwenkbar um eine, insbesondere mittig zur Öffnung angeordnete, Welle oder Achse in der Öffnung gelagert ist, und dass der Einbaurahmen und die Klappe jeweils aus Kunststoff gefertigt sind. Die erfindungsgemäße Klappe und der Einbaurahmen sind leicht herstellbar, da sie aus Kunststoff gefertigt sind. Die Klappe und die Öffnung können hinsichtlich der Querschnittsfläche beliebig ausgebildet sein. Die Klappe und damit auch die Öffnung können beispielsweise rund oder eckig ausgebildet sein.This object is achieved in that the flap is arranged in an opening frame having mounting frame and that the flap and the mounting frame form a mounting unit, wherein the flap pivotally about a, in particular centrally disposed to the opening, shaft or axis is mounted in the opening, and that the mounting frame and the flap are each made of plastic. The flap of the invention and the mounting frame are easy to produce, since they are made of plastic. The flap and the opening may be formed arbitrarily with respect to the cross-sectional area. The flap and thus the opening may be formed, for example, round or square.

Da die Klappe und der Einbaurahmen eine Montageeinheit bilden, die aus Kunststoff gefertigt ist, kann die Montageeinheit leicht im Werk montiert und auch vor Ort leicht installiert werden. Sofern die Klappe und die Welle eine Einheit bilden, ist die Montageeinheit zweiteilig ausgebildet. Das eine Teil bildet die Klappe mit der Welle, während der Einbaurahmen das zweite Teil darstellt.Since the flap and the mounting frame form a mounting unit, which is made of plastic, the mounting unit can be easily mounted in the factory and easily installed on site. If the flap and the shaft form a unit, the mounting unit is formed in two parts. One part forms the flap with the shaft, while the mounting frame is the second part.

Die Welle und die Klappe können einstückig, beispielsweise aus Kunststoff, ausgebildet sein. Es ist aber auch durchaus möglich, dass zwei Wellenstummel in entsprechende Aufnahmen der Klappe eingesetzt sind, wobei die Wellenstummel drehfest gegenüber der Klappe angeordnet sind.The shaft and the flap may be integrally formed, for example made of plastic. But it is also quite possible that two stub shafts are inserted into corresponding receptacles of the flap, wherein the stub shafts are arranged rotationally fixed relative to the flap.

Scfern die Klappe durch eine Achse mit dem Einbaurahmen verbunden ist, bietet es sich an, wenn eine Einrichtung zur Fixierung der Klappenstellung vorgesehen ist.If the flap is connected to the mounting frame by means of an axle, it makes sense if a device for fixing the flap position is provided.

Der Einbaurahmen weist einen die Öffnung teilweise, insbesondere die Öffnung vollständig, umgebenden und stutzenartig ausgebildeten Kragen auf. Durch den Kragen wird der durch die Öffnung strömende Luftstrom im Bereich der Öffnung gelenkt und gestützt.The mounting frame has a partially the opening, in particular the opening completely, surrounding and neck-like collar. Through the collar, the air flow flowing through the opening is directed and supported in the region of the opening.

Der Kragen weist zumindest im Bereich eines Endes der Welle oder der Achse eine die Welle oder die Achse rastend aufnehmende Ausnehmung auf. So kann die Ausnehmung beispielsweise zu ihrem Grund hin verjüngend, beispielweise nach Art eines v ausgebildet sein, wobei die Ausnehmung zumindest im Bereich einer Kante einen Vorsprung aufweist, der im eingerasteten Zustand der Welle bzw. der Achse ein unbeabsichtigtes Lösen der Welle bzw. der Achse aus der Ausnehmung verhindert.The collar has at least in the region of one end of the shaft or the axis of a shaft or the axis latching receiving recess. Thus, the recess, for example, tapering towards its bottom, for example, be formed in the manner of a v, wherein the recess has a projection at least in the region of an edge, the unintentional release of the shaft or the axis in the locked state of the shaft or the axis prevented from the recess.

Zumindest eine Ausnehmung und das mit dieser Ausnehmung zusammenwirkende Ende der Welle können so ausgebildet sein, dass eine Verdrehsicherung in Form einer haftungsverbessernden Oberfläche, wie z.B. einer Beschichtung, oder einer Struktur, wie z.B. einer Riffelung, vorgesehen ist, so dass damit eine selbstrastende Verstellung möglich ist. Bei der Beschichtung kann es sich beispielsweise um Gummi handeln. Aufgrund der selbstrastenden Verstellung kann bei der Montage die Klappe leicht in die gewünschte Postition verlagert werden.At least one recess and the end of the shaft cooperating with this recess may be formed such that an anti-twist device in the form of an adhesion-improving surface, such as e.g. a coating, or structure such as e.g. a corrugation, is provided, so that thus a self-locking adjustment is possible. The coating may be, for example, rubber. Due to the self-locking adjustment, the flap can easily be moved to the desired position during assembly.

Im Bereich zumindest eines Endes der Welle kann ein Verstellelement zur Verstellung der Klappenstellung vorgesehen sein. Die Klappe wird vor Ort vorzugsweise so eingebaut, dass das Verstellelement vom Raum her zugänglich ist, so dass damit die Klappenstellung jederzeit verändert werden kann.In the area of at least one end of the shaft, an adjusting element can be provided for adjusting the flap position. The flap is preferably installed on site so that the adjusting element is accessible from the room, so that thus the flap position can be changed at any time.

Der Einbaurahmen kann in einem Teilbereich seines äußeren Randes zumindest einen gelenkig, insbesondere über ein Filmscharnier, gelagerten Montageabschnitt aufweisen. Eine solche Ausgestaltung bietet sich an, wenn die Klappe in einem faltbaren Anschlusskasten eingesetzt wird.The mounting frame may have at least one articulated, in particular via a film hinge, mounted mounting portion in a portion of its outer edge. Such a configuration lends itself to when the flap is inserted in a foldable terminal box.

Um die Öffnung können zumindest zwei, vorzugsweise verteilt angeordnete, Paare an Klemmaufnahmen zur Aufnahme eines Randbereiches eines, insbesondere trichterähnlich ausgebildeten, Luftverteilelementes vorgesehen sein.At least two, preferably distributed, pairs of clamping receptacles for receiving an edge region of a, in particular funnel-like, air distribution element may be provided around the opening.

Bei der Erfindung erstreckt sich der Einbaurahmen im Wesentlichen in einer Ebene. Eine solche Ausgestaltung bietet sich insbesondere bei der Verwendung von Anschlusskästen an, bei denen der Gehäusewandungsbereich, in den die Klappe eingesetzt werden soll, eben ausgebildet ist.In the invention, the mounting frame extends substantially in one plane. Such a configuration is particularly suitable for the use of terminal boxes, in which the housing wall area, in which the flap is to be used, is flat.

Die Klappe kann eine Vielzahl an, insbesondere rund ausgebildeten, Durchgangsöffnungen aufweisen. Es bietet sich an, wenn die freie Querschnittsfläche, die durch alle Durchgangsöffnungen gebildet wird, bezogen auf die Gesamtfläche der Klappe etwa zwischen 20% und 80% liegt, vorzugsweise etwa zwischen 25% und 50% liegt, und insbesondere vorzugsweise etwa 32% beträgt. Dabei kann der Durchmesser einer Durchgangsöffnung zwischen 3 mm und 6 mm liegen, vorzugsweise 4 mm betragen.The flap can have a multiplicity of, in particular round, passage openings. It is advisable if the free cross-sectional area formed by all passage openings, based on the total area of the flap, is between about 20% and 80%, preferably between about 25% and 50%, and in particular preferably about 32%. In this case, the diameter of a passage opening can be between 3 mm and 6 mm, preferably 4 mm.

Dabei können die Durchgangsöffnungen gleichmäßig über zumindest einen Teilbereich der Fläche der Klappe verteilt angeordnet sein.In this case, the passage openings can be arranged distributed uniformly over at least a portion of the surface of the flap.

Um den Druckverlust im Bereich der Durchgangsöffnung möglichst gering zu halten und um eine unerwünschte Geräuschentwicklung zu vermeiden, bietet sich an, wenn zumindest einer der beiden umlaufenden Kantenbereiche des Randes zumindest einer Durchgangsöffnung abgerundet ist und/oder zumindest einer der beiden umlaufenden Kantenbereiche des äußeren Randes der Klappe abgerundet ausgebildet ist. Beträgt die Dicke der Klappe beispielsweise etwa 2,5 mm, bietet sich an, wenn vorzugsweise beide umlaufenden Kantenbereiche des Randes zumindest einer Durchgangsöffnung mit einem Radius zwischen 0,5 mm und 1 mm, vorzugsweise mit einem Radius von etwa 0,8 mm, abgerundet ausgebildet sind.In order to keep the pressure loss in the passage opening as small as possible and to avoid unwanted noise, it is advisable if at least one of the two circumferential edge regions of the edge of at least one passage opening is rounded and / or at least one of the two peripheral edge regions of the outer edge of the Flap rounded is formed. For example, if the thickness of the flap is about 2.5 mm, offers itself, if preferably both circumferential edge regions of the edge of at least one passage opening with a radius between 0.5 mm and 1 mm, preferably formed with a radius of about 0.8 mm, rounded.

In allen Figuren werden für gleiche bzw. gleichartige Bau-, teile übereinstimmende Bezugszeichen verwendet.In all figures, identical reference numerals are used for identical or similar parts.

In den Figuren 1 bis 6 ist eine als Drosselklappe ausgebildete Klappe 1 dargestellt, die zur Beeinflussung eines in einem raumluft- und klimatechnischem Anlage strömenden Volumenstroms ausgebildet ist.In the FIGS. 1 to 6 is designed as a throttle flap 1 is shown, which is designed to influence a flowing in a room air and air conditioning system volume flow.

Die Klappe 1 ist in einem eine Öffnung aufweisenden Einbaurahmen 2 angeordnet, wobei sich bei dem in den Fig. 1 bis 6 dargestellten Ausführungsbeispiel der Einbaurahmen 2 in einer Ebene erstreckt. Bei dem in den Fig. 15 bis 19 dargestellten Ausführungsbeispiel ist der Einbaurahmen 2 gekrümmt ausgebildet, damit er in einem Anschlusskasten 14, sowie er in den Fig. 13 und 14 dargestellt ist, eingesetzt werden kann.The flap 1 is arranged in an opening having a mounting frame 2, wherein in which in the Fig. 1 to 6 illustrated embodiment of the mounting frame 2 extends in a plane. In the in the 15 to 19 illustrated embodiment, the mounting frame 2 is curved so that it in a junction box 14, and he in the Fig. 13 and 14 is shown, can be used.

Die Klappe 1 und der Einbaurahmen 2 bilden eine Montageeinheit. Die Klappe 1 ist verschwenkbar um eine mittig zur Öffnung angeordnete Welle 3 in der Öffnung gelagert. Die Welle 3 ist gegenüber der Klappe 1 drehfest. Der Einbaurahmen 2 und die Klappe 1 bestehen aus Kunststoff.The flap 1 and the mounting frame 2 form a mounting unit. The flap 1 is pivotally mounted about a centrally disposed to the opening shaft 3 in the opening. The shaft 3 is against rotation of the flap 1. The mounting frame 2 and the flap 1 are made of plastic.

Wie den Figuren zu entnehmen ist, weist die Klappe 1 eine Vielzahl an rund ausgebildeten Durchgangsöffnungen 4 auf, die über Teilbereiche der Fläche der Klappe 1 gleichmäßig verteilt angeordnet sind.As can be seen from the figures, the flap 1 has a multiplicity of round passage openings 4 which are distributed uniformly over partial areas of the surface of the flap 1.

Wie beispielsweise den Figuren 5 und 6 oder 15 und 16 zu entnehmen ist, weist der Einbaurahmen 2 einen die Öffnung vollständig umgebenen und stutzenartig ausgebildeten Kragen 5 auf. Zur Lagerung der Welle 3, die an der Klappe 1 angeformt ist, weist der Kragen 5 in seinen gegenüberliegenden Bereichen jeweils eine die Welle 3 rastend aufnehmende Ausnehmung 6 auf, so dass die Klappe 1 werkzeugfrei in dem Einbaurahmen 2 montiert werden kann. Jede rastende Ausnehmung 6 verhindert, dass sich die Welle 3 ungewollt aus der Ausnehmung 6 lösen kann.Such as the FIGS. 5 and 6 or 15 and 16 can be seen, the mounting frame 2 a completely surrounded the opening and neck-like collar 5 on. For supporting the shaft 3, which is formed on the flap 1, the collar 5 has in its opposite areas in each case a shaft 3 latching receiving recess 6, so that the flap 1 can be mounted without tools in the mounting frame 2. Every resting Recess 6 prevents the shaft 3 can unintentionally release from the recess 6.
