Description

G i t e r G i t e r
Die Erfindung betrifft ein Gitter zum Ein- und/oder Aus¬ lassen von Luft mit einem Gehäusekasten, welcher in eine Öffnung eingesetzt ist und einen Abdeckrahmen aufweist.The invention relates to a grille for letting air in and / or letting out air with a housing box which is inserted into an opening and has a cover frame.
Derartige Gitter sind in Lüftungseinrichtungen sowie dem Ofenbau allgemein bekannt und in vielfältiger Form und Ausführung auf dem Markt erhältlich. Verwiesen wir hier auf beispielsweise das Kompaktgitter, welches in dem Gebrauchsmuster 88 03 613.8 oder der DE-OS 39 10 987 dargestellt ist.Such grilles are generally known in ventilation systems and furnace construction and are available on the market in a variety of forms and designs. We refer here to, for example, the compact grille, which is shown in utility model 88 03 613.8 or DE-OS 39 10 987.
In der Regel bilden diese Gitter eine Einheit und werden in eine Öffnung einer Wandung eines Kachelofens od.dgl. eingesetzt, wobei die Festlegung des Gitters in der Öffnung auf verschiedene Weise erfolgt. Einmal werden hierzu Schrauben verwendet, mit denen der Abdeckrahmen an der Wand festgelegt wird. Hierbei sind jedoch diese Schrauben von außen her sichtbar, was die an sich sehr schöne ästhetische Ausgestaltung des Gitters wieder erheblich verschandelt. Aus diesem Grunde wurde eine verdeckte Befestigungs¬ möglichkeit entwickelt. Zur verdeckten Befestigung müssen an den Stirnseiten oder an den Längsseiten der Gitter Federn oder Schraubelemente angebracht werden. Bei der Anordnung von Schraubelementen müssen die Stirn- oder Längsseiten an Lüftungsgittern aufgestanzt werden, damit die Betätigungsschraube für die verdeckte Befestigung innerhalb des Gitters von der Raumseite her betätigt werden kann, und der Befestigungsbügel sich am Einbaurahmen oder an einem sonstigen Bauteil befestigen läßt. Letzteres befindet sich wiederum außerhalb des Gitters als Traverse in einem Kanalsystem oder im Mauerwerk. Nur durch diese komplizierte Ausgestaltung ist eine leichte Montage möglich.As a rule, these grids form a unit and are or the like in an opening of a wall of a tiled stove. used, the grid being fixed in the opening in different ways. On the one hand, screws are used to fix the cover frame to the wall. Here, however, these screws are visible from the outside, which again considerably changes the aesthetic design of the grille. For this reason, a concealed fastening option was developed. For concealed fastening, springs or screw elements must be attached to the front or the long sides of the grille. When arranging screw elements, the front or long sides must be punched out on ventilation grilles so that the actuating screw for the concealed fastening within the grille can be operated from the room side, and the fastening bracket can be fastened to the mounting frame or another component. The latter, in turn, is located outside the grille as a traverse in a duct system or in the masonry. Easy assembly is only possible due to this complicated configuration.
Außer der komplizierten Ausgestaltung besteht jedoch noch der weitere erhebliche Nachteil, daß das Aufstanzen des Gitters wiederum einen nicht unerheblichen Durchbruch im sonst geschlossenen Gitterkasten erfordert. Jede Öffnung bedeutet aber zusätzliche Geräusche bei der Führung eines Luftstromes.In addition to the complicated configuration, there is, however, another significant disadvantage that punching out the grid again requires a not inconsiderable breakthrough in the otherwise closed grid box. However, each opening means additional noise when guiding an air flow.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Gitter der o.g. Art zu schaffen, welches einfach und mit möglichst wenig Durchbrüchen herzustellen ist, einfach in eine Öffnung eingesetzt werden kann und dabei ein anspre¬ chendes ästhetisches Aussehen erhält.The present invention has for its object to provide a grid of the above. To create a type that is easy to manufacture and with as few openings as possible, can be easily inserted into an opening and thereby receives an appealing aesthetic appearance.
Zur Lösung dieser Aufgabe führt, daß dem Abdeckrahmen lös¬ bar ein Blendrahmen aufgesetzt ist.To achieve this object, a cover frame is detachably placed on the cover frame.
Dieser Blendrahmen erlaubt es, daß das Gitter auf einfache Art und Weise durch ein Anschrauben mittels entsprechender Schraubelemente von außen her in einer Wand festgelegt werden kann, da der Blendrahmen anschließend die Schraubköpfe unsichtbar macht. Dem Kompaktgitter brauchen auch keine zusätzlichen Öffnungen eingeforrat zu werden, welche zu einer zusätzlichen Geräuschbelästigung führen.This frame allows the grille to be fixed in a simple manner by screwing it on using appropriate screw elements from the outside in a wall, since the frame then makes the screw heads invisible. Need the compact grille also no additional openings to be buried, which lead to additional noise pollution.
Zur Festlegung des Blendrahmens gegenüber dem Abdeckrahmen ist dem Abdeckrahmen eine Halteleiste zugeordnet, welche zumindest eine Rasteinrichtung zur Aufnahme eines Rastele¬ mentes an dem Blendrahmen aufweist. Die Rasteinrichtung soll so ausgestaltet sein, daß ein einfaches Aufklipsen des Blendrahmens auf den Abdeckrahmen möglich ist.To fix the frame relative to the cover frame, the cover frame is assigned a retaining bar which has at least one locking device for receiving a locking element on the frame. The latching device should be designed in such a way that the frame can be simply clipped onto the cover frame.
Für die Rasteinrichtung können unterschiedlichste Aus¬ gestaltungen vorgesehen sein. In einem bevorzugten Aus¬ führungsbeispiel besitzt die Halteleiste, bevorzugt aus Kunststoff gefertigt, einen Schlitz zur Aufnahme des Ab¬ deckrahmens. Das bedeutet, daß die eigentlichen Rastein¬ richtungen der Halteleiste nach außen weisen, während ein weiterer Teil der Halteleiste, nämlich ein Unterlegstrei¬ fen zwischen Abdeckrahmen und Wand angeordnet ist. Die Halteleiste dient in diesem Fall auch der Abstützung des Abdeckrahmens gegenüber der Wand und vor allem auch zu einer Geräuschisolierung. Von dem Gitter werden keine Ge¬ räusche mehr direkt auf die Wand übertragen, da der Ab¬ deckrahmen durch den Unterlegstreifen isoliert ist.A wide variety of configurations can be provided for the latching device. In a preferred embodiment, the retaining strip, preferably made of plastic, has a slot for receiving the cover frame. This means that the actual locking devices of the holding bar point outwards, while another part of the holding bar, namely a washer, is arranged between the cover frame and the wall. In this case, the retaining strip also serves to support the cover frame against the wall and, above all, to isolate noise. Noises from the grille are no longer transmitted directly to the wall, since the cover frame is insulated by the washer.
In einem einfachen Ausführungsbeispiel besteht die Rast¬ einrichtung aus einer Leiste mit einer eingeformten hin- terschnittenen Nut. Die Nut ist vorzugsweise im Quer¬ schnitt rund geformt und dient der Aufnahme eines Kugel¬ streifens, welcher dem Blendrahmen angeformt ist. Der Kugelstreifen kann in die hinterschnittene Nut eingeklipst werden. Unter Aufwendung einer entsprechenden Kraft ist jedoch auch ein leichtes Entfernen des Kugelstreifens aus dieser runden Nut möglich.In a simple exemplary embodiment, the latching device consists of a strip with a molded undercut groove. The groove is preferably round in cross section and serves to receive a spherical strip which is molded onto the frame. The ball strip can be clipped into the undercut groove. With the application of an appropriate force, however, it is also possible to easily remove the ball strip from this round groove.
Es soll ausdrücklich erwähnt werden, daß dies nur ein einfaches und wirkungsvolles Beispiel einer Rasteinrich- tung ist, daß darauf aber nicht die Erfindung beschränkt ist.It should be explicitly mentioned that this is just a simple and effective example of a tion is that the invention is not limited to this.
Der Blendrahmen selbst kann einstückig aus einem flexiblen Werkstoff, beispielsweise Kunststoff, hergestellt sein oder aber aus einzelnen Profilen, die dann auf Gehrung ge¬ schnitten und in den Eckbereichen zusammengefügt sind. Wird ein flexibler Werkstoff benutzt, so bietet es sich an, in dem Blendstreifen noch eine entsprechende Ausnehmung zum Einschieben eines Verstärkungsstreifens vorzusehen, so daß sich der Blendrahmen auch bei längerem Gebrauch nicht verziehen kann.The frame itself can be made in one piece from a flexible material, for example plastic, or from individual profiles, which are then mitred and joined in the corner areas. If a flexible material is used, it is advisable to provide a corresponding recess in the blind strip for inserting a reinforcing strip, so that the blind frame cannot warp even after prolonged use.
Ferner soll der Blendrahmen in seinem Querschnitt so aus¬ gestaltet sein, daß er mit entsprechend geformten Schen¬ keln den Abdeckrahmen bzw. die Halteleiste übergreift. Hierdurch verschwindet die gesamte Befestigungsanordnung des Gitters hinter einem formschön gestalteten Blendrah¬ men.Furthermore, the cross-section of the frame should be designed such that it overlaps the cover frame or the holding strip with correspondingly shaped legs. As a result, the entire fastening arrangement of the grille disappears behind an elegantly designed window frame.
Ein derartiger Blendrahmen und auch die Halteleiste können auch bei bereits bestehenden Gittern zur Anwendung ge¬ bracht werden. Hierdurch ist es möglich, bereits eingebau¬ te Gitter nachträglich mit einem besseren "Outfit" durch ein Abdecken der Befestigungselemente zu versehen. Ferner kann diesen Gittern jetzt wiederum ein anderes Aussehen durch den Blendrahmen gegeben werden, was die Gitter wie¬ der interessanter macht.Such a frame and also the retaining strip can also be used for existing grilles. In this way it is possible to subsequently provide already installed grids with a better "outfit" by covering the fastening elements. Furthermore, these gratings can now be given a different appearance by the frame, which makes the gratings more interesting.
Ein weiterer großer Vorteil liegt auch darin, daß durch ein Gitter sämtliche bisher auf dem Markt befindlichen verschiedenartigen Gitterausführungen auf diese eine Gitterausführung konzentriert werden können. Dies stellt für die Fertigung einen großen Vorteil dar. Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzug¬ ter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt inAnother great advantage is that a grid can be used to concentrate all of the various types of grille currently on the market. This is a great advantage for manufacturing. Further advantages, features and details of the invention emerge from the following description of preferred exemplary embodiments and with reference to the drawing; this shows in
Fig. 1 eine Draufsicht auf ein Gitter mit einem erfin¬ dungsgemäßen Blendrahmen:1 shows a plan view of a grating with a frame according to the invention:
Fig. 2 einen vergrößert dargestellten Querschnitt durch einen Eckbereich des Blendrahmens und Gitters in Gebrauchslage entlang Linie II - II in Fig. 1.FIG. 2 shows an enlarged cross section through a corner region of the frame and grille in the position of use along line II-II in FIG. 1.
In Fig. 1 ist ein handelsübliches Gitter 1 mit Lamellen 2 gezeigt, welches auch als Kompaktgitter bezeichnet wird. In der Regel sind die Lamellen 2 in entsprechenden Seiten¬ wänden schwenkbar gelagert, so daß durch die Lamellen 2 ein Luftein- bzw. -austritt aus dem bzw. in das Gitter 1 ermöglicht wird. Es gibt viele Ausgestaltungsmöglichkeiten für ein derartiges Gitter, die alle vom vorliegenden Er¬ findungsgedanken umfaßt sein sollen.In Fig. 1, a commercially available grille 1 with lamellae 2 is shown, which is also referred to as a compact grille. As a rule, the slats 2 are pivotally mounted in corresponding side walls, so that the slats 2 allow air to enter and exit from or into the grille 1. There are many design options for such a grating, all of which are intended to be encompassed by the present inventive concept.
Erfindungsgemäß ist diesem Gitter 1 ein Blendrahmen 3 zu¬ geordnet, der in dem in Fig. 1 gezeigten Ausführungsbei¬ spiel aus vier Profilen 3a, 3b, 3c und 3d besteht. Diese Profile sind auf Gehrung geschnitten und in ihren Eckbe¬ reichen zusammengehalten. Das Zusammenhalten kann durch entsprechende Verbinungselemente, Kleben usw. erfolgen. Im Rahmen der Erfindung liegt jedoch auch, daß der komplette Blendrahmen aus beispielsweise einem Kunststoff gespritzt oder aus Aluminium oder dergleichem Material beispielswei¬ se durch Stanzen einstückig hergestellt und wie gewünscht abgekantet wird.According to the invention, a grille 3 is assigned to this grille 1, which in the exemplary embodiment shown in FIG. 1 consists of four profiles 3a, 3b, 3c and 3d. These profiles are mitred and held together in their corner areas. The holding together can be done by appropriate connection elements, gluing, etc. However, it is also within the scope of the invention that the complete frame is injection molded from, for example, a plastic or made of aluminum or the like material in one piece, for example by punching, and is bent as desired.
Gem. Fig. 2 wird das Gitter 1 mittels Befestigungs¬ elementen 4, beispielsweise Schrauben, in einer Öffnung 5 einer Wand 6 od.dgl. festgelegt. Hierzu sind von einem Gehäusekasten 7 des Gitters 1 Streifen 8 und 9 ab- gekantet, welche sich in den Eckbereichen überlappen und einen Abdeckrahmen 10 für die Öffnung 5 ausbilden. Das Be¬ festigungselement 4 durchsetzt diesen Abdeckrahmen 10 und ist dann in die Wand 6 eingeschraubt.2, the grid 1 is fastened by means of fastening elements 4, for example screws, in an opening 5 of a wall 6 or the like. fixed. For this purpose, strips 8 and 9 are removed from a housing box 7 of the grid 1. edged, which overlap in the corner areas and form a cover frame 10 for the opening 5. The fastening element 4 passes through this cover frame 10 and is then screwed into the wall 6.
Vor dem Festlegen des Gitters 1 an der Wand 6 ist dem Ab¬ deckrahmen 10 eine Halteleiste 11 aufgeschoben, welche Rasteinrichtungen 12a und 12b für eine Festlegung des Blendrahmens 3 ausbildet. Bevorzugt besteht diese Halte¬ leiste 11 aus Kunststoff, wobei beispielsweise im Spritz¬ gießverfahren die Rasteinrichtungen 12 leicht hergestellt werden können.Before the grille 1 is fixed to the wall 6, a retaining strip 11 is pushed onto the cover frame 10, which forms locking devices 12a and 12b for fixing the frame 3. This holding strip 11 is preferably made of plastic, and the locking devices 12 can be easily manufactured, for example, by injection molding.
Im vorliegenden Ausführungsbeispiel ist in die Halteleiste 11 ein Schlitz 13 eingeformt, welcher der Aufnahme des Ab¬ deckrahmens 10 dient. Hierdurch ist der Abdeckrahmen 10 gleichzeitig durch einen Unterlegstreifen 14 gegenüber der Wand 6 abgestützt. Dies hat den Vorteil, daß zum einen eventuelle Passungenauigkeiten der Oberfläche der Wand 6 gegenüber dem Abdeckrahmen 10 ausgeglichen werden. Zum an¬ deren bewirkt der Unterlegstreifen 14 aber auch eine Dämp¬ fung, so daß Geräusche, die beispielsweise durch einen Luftstrom oder durch ein Klappern der Lamellen 2 entste¬ hen, nicht auf die Wand 6 übertragen werden.In the present exemplary embodiment, a slot 13 is formed in the holding strip 11, which is used to receive the cover frame 10. As a result, the cover frame 10 is supported at the same time by a washer 14 against the wall 6. This has the advantage that, on the one hand, possible inaccuracies in the surface of the wall 6 with respect to the cover frame 10 are compensated for. On the other hand, the washer 14 also causes damping, so that noises which arise, for example, from an air stream or from a rattling of the slats 2, are not transmitted to the wall 6.
Vom Erfindungsgedanken soll jedoch auch gedeckt sein, wenn die Halteleiste 11 nur aus den auf den Abdeckrahmen 10 aufgesetzten Rasteinrichtungen 12 besteht, die zwischen sich eine Ausnehmung 15 zur Aufnahme eines Schraubenkopfes 16 ausbilden.However, the idea of the invention is also intended to cover if the retaining strip 11 consists only of the latching devices 12 which are placed on the cover frame 10 and which form a recess 15 between them for receiving a screw head 16.
Ein einfaches Ausführungsbeispiel einer Rasteinrichtung 12 weist eine Leiste 17 auf, in welche eine hinterschnittene Nut 18 eingeformt ist. Diese Nut 18 ist im Querschnitt im gezeigten Ausführungsbeispiel kugelig ausgebildet und dient der Aufnahme eines entsprechenden Kugelstreifens 19, welcher einstückig mit dem Blendrahmen 3 verbunden ist. Im vorliegenden Ausführungsbeispiel sind zwei Rasteinrich¬ tungen 12a und 12b vorgesehen, so daß ebenfalls zwei Lei¬ sten 17a und 17b mit jeweils einer Nut 18a und 18b sowie zwei Kugelstreifen 19a und 19b an dem Blendrahmen 3 vorge¬ sehen sind.A simple exemplary embodiment of a latching device 12 has a strip 17 into which an undercut groove 18 is formed. This groove 18 is spherical in cross section in the exemplary embodiment shown and serves to accommodate a corresponding spherical strip 19 which is integrally connected to the frame 3. In the present exemplary embodiment, two locking devices 12a and 12b are provided, so that two strips 17a and 17b, each with a groove 18a and 18b and two spherical strips 19a and 19b, are also provided on the frame 3.
Zwischen den beiden Kugelstreifen 19a und 19b ist in dem Abdeckrahmen 3 noch eine Ausnehmung 20 vorgesehen, in wel¬ che beispielsweise eine Verstärkungsschiene eingeschoben werden könnte.Between the two spherical strips 19a and 19b, a recess 20 is also provided in the cover frame 3, into which, for example, a reinforcing rail could be inserted.
Der Blendrahmen 3 ist im übrigen so ausgestaltet, daß er einerseits mit einem Schenkel 21 die Halteleiste 11 gänz¬ lich übergreift und an der Wand 6 anschlägt. Andererseits übergreift er mit einem Stützschenkel 22 ebenfalls die Halteleiste bzw. die Rasteinrichtung 12 und stützt sich gegen eine Oberfläche des Abdeckrahmens 10 bzw. des Git¬ ters 1 ab. Durch diese Ausgestaltung verschwindet der Ab¬ deckrahmen mit dem Befestigungselement und der Halteleiste 11 völlig unter dem Blendrahmen 3. The frame 3 is otherwise designed such that it completely overlaps the retaining strip 11 with a leg 21 and strikes the wall 6. On the other hand, it also overlaps the retaining strip or the latching device 12 with a support leg 22 and is supported against a surface of the cover frame 10 or the grille 1. As a result of this configuration, the cover frame with the fastening element and the holding strip 11 completely disappears under the frame 3.
