Description

"Hohlprofil zur Bildung von Lüftunqssteuerunαsklappen" "Hollow profile for the formation of ventilation control valves"
Die Erfindung richtet sich auf ein Hohlprofil mit einem Aufnahmebereich für in der Gebrauchslage die Drehung des Profiles bewirkende Elemente der im Anspruch 1 angegebenen Gattung.The invention relates to a hollow profile with a receiving area for the rotation of the profile effecting elements of the type specified in claim 1 in the position of use.
Aus der AT-328 676 ist ein gattungsbildendes Profil be¬ kannt, wobei dort zwei unterschiedlich geformte Bleche zu einem Hohlprofil randseitig zusammengefalzt sind. Um eine innige Verbindung zu schaffen sind dort besondere Maßnahme an den Rändern getroffen. Zum weiteren Stand der Technik sei noch auf die DE-C-22 08 259 und die DE-A-23 46 784 verwiesen, wobei letztere das Verklemmen zweier gleicher Bleche unter Einschluß der Nabenachse aneinander zeigt.A generic profile is known from AT-328 676, two differently shaped sheets being folded together at the edge to form a hollow profile. In order to create an intimate connection, special measures have been taken at the edges. For further prior art, reference is made to DE-C-22 08 259 and DE-A-23 46 784, the latter showing the jamming of two identical sheets, including the hub axle, against one another.
Ein Hohlprofil aus Aluminium ist aus dem DE-U-91 06 188 be¬ kannt mit einer dem Profil zugeordneten Ausgestaltung im Schwenkachsenbereich. Dieses Profil weist eine Reihe von Vorteilen auf und hat sich in der Praxis bewährt. Ein Nach¬ teil eines solchen Aluminium-Hohlprofiles besteht aller¬ dings darin, daß es vergleichsweise kostspielig ist.A hollow profile made of aluminum is known from DE-U-91 06 188 with a configuration associated with the profile in the swivel axis area. This profile has a number of advantages and has proven itself in practice. A disadvantage of such an aluminum hollow profile is, however, that it is comparatively expensive.
Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der unter Beibehaltung der Vorteile des oben genannten Alu- minium-Hohlprofiles die Vorteile einer preisgünstigeren Produktionsweise ermöglicht werden bei einem gattungsgemä¬ ßen, aus Blechen gebildeten Hohlprofil.The object of the invention is to provide a solution with which, while maintaining the advantages of the above-mentioned aluminum minium hollow profile, the advantages of a more economical production method are made possible with a generic hollow profile formed from sheet metal.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das Halbprofil aus zwei identischen, umschlagsymmetrisch miteinander verbundenen und einen Aufnahmebereich für eine Schwenkachse bildenden Halbprofilen gebildet ist, wobei je¬ des Halbprofil im Mittelbereich zwei in der Gebrauchslage nach innen weisende, gefalzte Profilschenkel aufweist, die in der Verschlußlage nebeneinanderliegend den Aufnahmebe¬ reich der Schwenkachse bilden.This object is achieved according to the invention in that the half-profile is formed from two identical half-profiles which are connected symmetrically to one another and form a receiving area for a pivot axis, each half-profile in the central region having two folded profile legs pointing inwards in the position of use, which in the closed position lying next to each other form the receiving area of the pivot axis.
Mit der Erfindung wird erreicht, daß es zur Herstellung des Hohlprofiles nur der Herstellung eines Halbprofiles auf ei¬ ner Kaltverformungsanlage bedarf, die dann auch die benö¬ tigten Längen geschnitten, umschlagsymmetrisch gegeneinan¬ der gesetzt und miteinander verbunden werden, was grund¬ sätzlich, wie auch der Stand der Technik zeigt, in unter¬ schiedlicher Weise möglich ist.With the invention it is achieved that the manufacture of the hollow profile only requires the production of a half-profile on a cold-forming machine, which then also cuts the required lengths, is set symmetrically against one another and is connected to one another, which is basically how the prior art also shows that this is possible in different ways.
Dabei kann es zweckmäßig sein, die nach innen weisenden Profilschenkel etwa um das Maß ihrer Breite, bezogen auf die Mittelachse des Gesamtprofiles, versetzt an den Halb¬ profilen anzuordnen, wie dies die Erfindung ebenfalls vor¬ sieht. Vorteilhaft kann es sein, wenn die bei jedem Halbprofil an dem zwischen den beiden nach innen weisenden Profilschen¬ keln vorgesehenen Profilbereich schräg angestellte Profil¬ bereiche anschließen, die außenrandseitig in gerade Profil¬ stücke auslaufen, die in der Gebrauchslage an den geraden Profilstücken des korrespondierenden Halbprofiles anliegen.It may be expedient to arrange the inward-pointing profile legs offset on the half-profiles approximately by the dimension of their width, based on the central axis of the overall profile, as is also provided by the invention. It can be advantageous if the profile areas provided obliquely in each half profile on the profile area provided between the two inwardly pointing profile legs, which end on the outside edge in straight profile pieces, which in the use position on the straight profile pieces of the corresponding half profile issue.
Diese geraden Profilstücke können zur Verbindung der beiden Halbprofile herangezogen werden, hier kann beispielsweise eine Punktverschweißung vorgesehen sein.These straight profile pieces can be used to connect the two half profiles, for example spot welding can be provided here.
Um das Gesamtprofil im Wege der Kaltverformung zu erzeugen sieht die Erfindung aber in weiterer Ausgestaltung auch vor, daß jedes Halbprofil an einer freien Längskante einen Umbördelungssteg aufweist, der zur Befestigung des anderen Halbprofiles über dessen anliegendes Profilstück falzbar ist.In order to produce the overall profile by means of cold forming, the invention also provides in a further embodiment that each half-profile has a flanging web on a free longitudinal edge, which can be folded over the adjacent profile piece for fastening the other half-profile.
Weitere Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aufgrund der nachfolgenden Beschreibung sowie anhand der Zeichnung. Diese zeigt inFurther features, details and advantages of the invention result from the following description and from the drawing. This shows in

Halbprofile zur Bildung eines Hohlprofiles nach der Erfindung vor dem endgültigen Zusammenfügen, Fig. 2 ein fertiges Profil in verkleinertem Maßstab sowie inHalf profiles to form a hollow profile according to the invention before final assembly, Fig. 2 shows a finished profile on a reduced scale and in
Fig. 3 eine geringfügig abgewandelte Profilform im Quer¬ schnitt.3 shows a slightly modified profile shape in cross section.
Das allgemein mit 1 bezeichnete Hohlprofil wird von zwei identisch ausgebildeten Metall-Halbprofilen 2 gebildet, die in Fig. 1 zur Unterscheidung mit 2a und 2b bezeichnet sind.The hollow profile, generally designated 1, is formed by two identically designed metal half profiles 2, which are designated by 2a and 2b in FIG. 1 for distinction.
Die Halbprofile 2 sind beispielsweise im Wege der Kaltver¬ formung mit zwei nach innen weisenden Profilschenkeln 3 ausgestattet, die gegenüber der mit 4 bezeichneten Profil¬ mittelachse derart versetzt angeordnet sind, daß bei dem Zusammenfügen der Halbprofile 2a und 2b gemäß Pfeil 5 in Fig. 1 sich ein symmetrischer, mit 6 bezeichneter Aufnahme- raum bildet, in dem beispielsweise ein Schwenkvierkant 7, der eine Drehachse bilden kann, einschiebbar ist, was in Fig. 1 strichpunktiert angedeutet ist.The half-profiles 2 are, for example, equipped with two inward-pointing profile legs 3 by means of cold forming, which are offset with respect to the profile center axis designated by 4 such that when the half-profiles 2a and 2b are joined according to arrow 5 in FIG. 1 a symmetrical receiving space, designated 6, is formed in which, for example, a swivel square 7, which can form an axis of rotation, can be inserted, which is indicated by dash-dotted lines in FIG. 1.
Zwischen den nach innen weisenden, gefalzten Profilschen¬ keln 3 ist jedes Halbprofil nach dem dargestellten Ausfüh¬ rungsbeispiel mit einem geraden Profilbereich 7 ausgerü¬ stet, an den sich schräg nach innen verlaufende Profilbe¬ reiche 8 anschließen, die außenrandseitig je in ein gerades Profilstück 9 und 9a übergehen, wobei das eine gerade Pro¬ filstück 9a noch einen Umbördelungssteg 10 aufweist, der nach dem Zusammenfügen dann über das anliegende Profilstück 9 des anderen Halbprofiles falzbar ist, wie sich dies aus Fig. 2 ergibt.Between the inwardly facing, folded profile legs 3, each half-profile according to the exemplary embodiment shown is equipped with a straight profile area 7, to which profile areas 8 which run obliquely inwards connect, each of which is in a straight line on the outer edge side Pass over profile pieces 9 and 9a, the one straight profile piece 9a also having a flanging web 10, which after assembly can then be folded over the adjacent profile piece 9 of the other half profile, as can be seen in FIG. 2.
Erkennbar läßt sich das erfindungsgemäße Hohlprofil 1 nur im Wege der Falzung bzw. Kaltverformung herstellen: Das Halbprofil 2 wird zunächst aus einem Blech-Bandmaterial hergestellt, auf gewünschte Längen abgeschnitten, umschlag¬ symmetrisch mit einem entsprechenden Halbprofil 2b zusam¬ mengefügt, wobei dann die Randseiten durch Umbördelung auf einer Profilieranlage des Steges 10 aneinander verbunden werden, so daß sich hier ein geschlossenes Halbprofil 1 er¬ gibt.The hollow profile 1 according to the invention can only be recognized by folding or cold forming: The half profile 2 is first made from a sheet metal strip material, cut to the desired lengths, joined symmetrically with a corresponding half profile 2b, with the edge sides then can be connected to one another by flanging on a profiling system of the web 10, so that here there is a closed half-profile 1.
In Fig. 3 ist ein abgewandeltes Ausführungsbeispiel des er- findungsgemäßen Profiles 1" dargestellt, das sich insbeson¬ dere dadurch auszeichnet, daß Wandflächen der Halbprofile mit Verstärkungssicken 11 versehen sind. In der Figur ist auch angedeutet, daß die Außenrandbereiche nach Rückfalzung des Steges 10' miteinander verkröpft sind, die Verkröpfung trägt das Bezugszeichen 12.3 shows a modified exemplary embodiment of the profile 1 "according to the invention, which is characterized in particular by the fact that wall surfaces of the half-profiles are provided with reinforcing beads 11. The figure also indicates that the outer edge regions after the web 10 has been folded back 'are cranked together, the cranking bears the reference number 12.
Natürlich sind die beschriebenen Ausführungsbeispiele der Erfindung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. So kann der Aufnahmebereich 6 rechteckig oder teilweise gekrümmt gestaltet sein, die schräg verlaufenden Profilbereiche 8 können mit weiteren Versteifungsrippen versehen sein bzw. mit weiteren nach in¬ nen weisenden Stegen, die beiden Halbprofile können aus ei¬ nem entsprechend breiten Metallband parallel nebeneinander liegend gefalzt werden, so daß sie bei der Montage nur halb gegeneinander gefaltet werden müssen, derart, daß sie nur an einer Seite zu verbinden sind. In der Montagelage können die stirnseitigen Profilenden auch von Elementen zur Erzeu¬ gung einer Schwenkbewegung ganz oder teilweise übergriffen sein, ohne daß Teile in den Aufnahmebereich 6 eingreifen u. dgl. mehr. Of course, the described exemplary embodiments of the invention can be modified in many ways without the To leave basic ideas. Thus, the receiving area 6 can be designed to be rectangular or partially curved, the oblique profile areas 8 can be provided with further stiffening ribs or with further webs pointing inwards, the two half-profiles can be folded parallel from one another from a correspondingly wide metal strip , so that they only have to be folded half against each other during assembly, in such a way that they can only be connected on one side. In the assembly position, the front profile ends can also be overlapped in whole or in part by elements for generating a pivoting movement, without parts interfering with and receiving parts 6.
