Abstract
Description
Die Erfindung betrifft eine Gelenkverbindung und eine daraus hergestellte Faltwand bzw. Falttor aus mindestens 2 Profilen und einem weiteren Klemmprofil, das als zweiteilige Achse für die beiden Lagerschalen des Gelenks ausgebildet ist, wobei die Profile an der Stoßebene zur Gelenkseite je eine sicherförmige Nut und parallel zur Stoßebene je einen zur Profilseite hin geöffneten hakenförmigen Fortsatz aufweisen, wobei der Außenbogen der sichelförmigen Nut auf einem Umkreis liegt, der die Stoßebene und die gelenkseitige Außenfläche der Profile berührt und die Innenfläche des hakenförmigen Fortsatzes als eine konzentrisch zum Umkreis liegende zylinderförmige Nut ausgebildet ist und wobei ferner das Klemmprofil aus einem im Querschnitt C-förmigen Profil mit je einem Auslaufende und je einer der anderen gegenüberliegenden Gleitfläche versehen ist und bei dem das Klemmprofil mit den Auslaufenden in den Innenflächen der hakenförmigen Fortsätze drehbar gelagert ist.The invention relates to an articulated connection and a folding wall or folding door made therefrom of at least 2 profiles and a further clamping profile, which is designed as a two-part axis for the two bearing shells of the joint, the profiles on the joint plane to the joint side each having a secure groove and parallel to Butt plane each have a hook-shaped extension open towards the profile side, the outer arc of the crescent-shaped groove lying on a circumference which touches the butt plane and the joint-side outer surface of the profiles and the inner surface of the hook-shaped extension is designed as a cylindrical groove lying concentrically to the circumference, and wherein furthermore, the clamping profile is provided with a cross-sectionally C-shaped profile, each with an outlet end and one of the other opposite sliding surfaces, and in which the clamping profile is rotatably mounted with the outlet ends in the inner surfaces of the hook-shaped extensions.
Eine Gelenkverbindung der eingangs genannten Art ist aus der US-A-4,679,277 bekannt. Mit dieser Gelenkverbindung sind jedoch keine formschlüssigen Verbindungen an den Stirnseiten möglich und auch keine glatten Außenflächen im gestreckten Zustand der Gelenkprofile. Ferner fehlt der bekannten Gelenkverbindung ein definierter Anschlag in den jeweiligen Endpositionen.A joint connection of the type mentioned is known from US-A-4,679,277. With this articulated connection, however, no form-fitting connections are possible on the end faces and also no smooth outer surfaces in the extended state of the articulated profiles. Furthermore, the known articulated connection lacks a defined stop in the respective end positions.
Aus der FR-A-2 311 914 ist ein Türscharnier bekannt, bei dem ebenfalls kein bündiges und flächiges Aufeinanderliegen der Türprofile im gefalteten Zustand möglich ist. Äußere Einwirkungen in Form von Schmutz und Staub können daher ungehindert das Gelenkinnere erreichen.A door hinge is known from FR-A-2 311 914, in which it is likewise not possible for the door profiles to lie flush and flat on one another in the folded state. External influences in the form of dirt and dust can therefore reach the inside of the joint unhindered.
Für die Verwendung der Gelenkverbindungen bei großflächigen Profilen wie z.B. Schiebetüren, Falttoren, Ladebordwänden oder Frachtraumabdeckungen müssen sehr steife, hohen mechanischen Anforderungen genügende Konstruktionen gewählt werden. Diese sollen sowohl im gefalteten als auch im gestreckten Zustand der Gelenkteile hohe Belastungen, insbesondere Querkraftbeanspruchungen aufnehmen können. Dabei ist auch das Reibungsverhalten hinsichtlich des Verschleißes, des Kraftaufwandes und der Geräuschentwicklung beim Betätigen der Gelenkverbindung zu beachten.For the use of the articulated connections on large-area profiles such as Sliding doors, folding gates, tail lifts or cargo space covers must be chosen very rigid structures that meet high mechanical requirements. These should be able to absorb high loads, in particular lateral loads, both in the folded and in the stretched state of the joint parts. The friction behavior with regard to wear, effort and noise when operating the articulation must also be taken into account.
Aufgabe der vorliegenden Erfindung ist es,eine Gelenkverbindungen mit einem Drehwinkel von mindestens 180° mit einer glatten Außenfläche der Profile im gestreckten Zustand zu entwickeln, die unempfindlich gegenüber äußeren Einwirkungen, wie Schmutz, Staub und Stoß ist, sowohl im gestreckten, wie im gefalteten Zustand hohe Querkraftbelastungen aufnehmen kann und ein verbessertes Reibungsverhalten aufweist.The object of the present invention is to develop an articulated connection with a rotation angle of at least 180 ° with a smooth outer surface of the profiles in the stretched state, which is insensitive to external influences, such as dirt, dust and shock, both in the stretched and in the folded state can absorb high lateral loads and has an improved friction behavior.
Diese Aufgabe wird durch die in dem Patentanspruch 1 angegebenen Merkmale gelöst. Durch die besondere Gestaltung der T-förmig ausgebildeten Auslaufenden wird eine glatte Außenfläche im gestreckten Zustand der Gelenkteile und ein bündiger Abschluß bei gefalteter Anordnung ermöglicht. Die Positionierung der Gleit- bzw. Wälzflächen des Gelenkes zwischen den Metallprofilen auf verschiedenen Kreisradien gestattet es, daß nur ein Teilsegment die Wälz- bzw. Gleitflächenfunktion übernimmt und durch gleichzeitige Verwendung von Gleitprofilen an wenigstens einer der beiden Spitzen der T-förmigen Auslaufenden das Reibungsverhalten der Gelenkverbindung wesentlich verbessert wird.This object is achieved by the features specified in
Die Anwendungsfälle der vorliegenden Erfindung erstrecken sich auf den gesamten Bereich der beweglichen Scharnierund Gelenkkonstruktionen und liegen vorzugsweise bei Falttorsegmenten, Ladebordwänden oder Frachtraumabdeckungen im stationären Bereich oder im Transportbereich. Beispielsweise können Güterwagen mit Falttorsegmenten von bis zu 7 m Länge ausgerüstet werden, die eine Be- und Entladung über die gesamte Längsseitenebene ermöglichen. Bei mehreren miteinander gelenkig verbundenen Falttorsegmenten werden diese zieharmonikaartig zusammengefaltet. In diesem Zustand liegen sie flach aufeinander mit parallel verlaufendem Ober- und Unterteil.The applications of the present invention extend to the entire area of the movable hinge and joint constructions and are preferably in the case of folding door segments, tail lifts or cargo hold covers in the stationary area or in the transport area. For example, freight wagons can be equipped with folding gate segments of up to 7 m in length, which enable loading and unloading across the entire long side level. In the case of a plurality of folding door segments which are connected to one another in an articulated manner, these are folded like an accordion. In this state, they lie flat on top of each other with the upper and lower parts running parallel.
Eine Faltwand mit einer Gelenkverbindung nach einem der Ansprüche 1 - 10 ist im Patentanspruch 11 beansprucht.A folding wall with an articulated connection according to one of claims 1-10 is claimed in
Im geschlossenen Zustand des Falttores geben die Gelenkverbindungen der Faltwand eine große Steifigkeit durch mehrfache Abstützung mit weit auseinanderliegenden Stützlinien in der Stoßebene.When the folding door is closed, the articulated connections of the folding wall provide great rigidity through multiple supports with widely spaced support lines in the joint plane.
Zur Vergrößerung der Steifigkeit im gestreckten Zustand können die Gelenke am Stoßende der sich berührenden Strangpreßprofile entlastet werden. Dies geschieht durch eine Verdickung auf der Wälzfläche für den Drehwinkelbereich von 0 - 10° , gemessen von der Null-Lage in gestrecktem Zustand bis zum Winkel von 10 ° beim Zusammenfalten des Gelenks.To increase the stiffness in the extended state, the joints at the butt end of the touching extruded profiles can be relieved. This is done by a thickening on the rolling surface for the angle of rotation range from 0 - 10 °, measured from the zero position in the stretched state up to the angle of 10 ° when folding the joint.
Eine Sicherung gegen zusätzliches Verschieben der Strangpreßprofile im gestreckten Zustand wird durch eine Nut-Zapfenverbindung am Stoßende erreicht. Diese behindert die Drehbewegung nicht, da beim Abwälzen auf der Verdickung die Strangpreßprofile sofort voneinander abheben.Protection against additional displacement of the extruded profiles in the stretched state is achieved by means of a tongue and groove connection at the butt end. This does not hinder the rotary movement, since the extruded profiles immediately lift off from each other when they roll on the thickening.
Im folgenden wird die Erfindung anhand von 3 Ausführungsbeispielen näher erläutert.The invention is explained in more detail below on the basis of 3 exemplary embodiments.

In Figuren 1 und 2 sind die Strangpreßprofile 1, 2 mittels eines im Querschnitt C-förmigen Klammerprofils (3) gelenkig miteinander verbunden. Das Klammerprofil (3) besteht aus einem oben- und einem untenliegenden Schenkel mit je einer abgerundeten Schenkelaußenfläche (6, 7), die mit jeweils einem zugehörigen T-förmig ausgebildeten Auslaufende (8, 9) verbunden ist. Die Schenkel des Klammerprofils (3) greifen in entsprechend ausgebildete Nuten (4, 5) am Kopfende der Profile (1, 2) ein. Die Schenkelaußenfläche (6, 7) des Profils (3) ist vorzugsweise als Kreissegment ausgebildet und gleitet beim Drehen des Gelenks in der entsprechenden Nut (4, 5), die ebenfalls Kreissegmentform aufweist.In FIGS. 1 and 2, the
Die Auslaufenden 8, 9 des Klammerprofils 3 sind vorzugsweise im Querschnitt zylindrisch ausgebildet und gleiten in entsprechend geformten Nuten 10, 11 eines hakenförmigen Fortsatzes 12, 13 am Kopfteil der Profile der 1, 2. Unter Anwendung der bei der Beschreibung eines Gelenks üblichen Begriffe "Welle" und "Lagerschale" lassen sich die Funktionen der Einzelteile im vorliegenden Fall wie folgt definieren:The outlet ends 8, 9 of the
Das erfindungsgemäße Gelenk zwischen zwei Strangpreßprofilen weist getrennte Funktionen mit innen- und außenliegenden Gleitflächen für Welle und Lagerschale auf. Die Welle wird durch das Klammerprofil 3 gebildet, die Lagerschale durch die Nuten 4, 5 bzw. 10, 11. Das Klammerprofil 3 hat an den Auslaufenden 8, 9 und an den Schenkeln 6, 7 jeweils getrennte Gleitflächen. Die Bezeichnung der Gleitflächen an den Auslaufenden als innere Gleitfläche und die an den Schenkeln liegende als äußere Gleitfläche bezieht sich auf die Funktion des Gelenks im gestreckten Zustand gemäß Fig. 1. Hier liegt die Gleitfläche zwischen den Auslaufenden 8, 9 und den Nuten 10, 11 "innen" und die Gleitfläche zwischen den Nuten 4, 5 und den Schenkeln 6, 7 "außen". bezogen auf den Querschnitt durch das erfindungsgemäße Gelenk. Die Auslaufenden des C-förmigen Klammerprofils 3 dienen als innere Wellensegmente und die Schenkelaußenfläche des Klammerprofils aus äußere Wellensegmente mit jeweils zugeordneten Gleitflächen. Die innere Gleitfläche korrespondiert mit den Nuten 10, 11, die als innere Lagerschalensegmente wirken. Die äußeren Gleitflächen werden durch die Nuten 4, 5 gebildet, die als äußere Lagerschalensegmente dienen.The joint according to the invention between two extruded profiles has separate functions with internal and external sliding surfaces for the shaft and bearing shell. The shaft is formed by the
Die geometrische Lage der inneren und äußeren Gleitflächen zueinander und bezüglich der Lage der Strangpreßprofile ist durch die Radien der jeweils zugehörigen Teilkreise definiert. Das äußere Lagerschalensegment liegt auf einem die Verlängerung der Strangpreßprofilaußenseite und die Trennlinie zwischen den Profilen berührenden Teilkreis. Das innere Lagerschalensegment liegt auf einem Teilkreis, der konzentrisch zum äußeren Teilkreis mit einer Radiusdifferenz von der Dicke des Klammerprofils 3 plus der Dicke des hakenförmigen Fortsatzes 12, 13 angeordnet ist.The geometrical position of the inner and outer sliding surfaces with respect to one another and with respect to the position of the extruded profiles is defined by the radii of the respective partial circles. The outer bearing shell segment lies on a partial circle touching the extension of the extruded profile outside and the dividing line between the profiles. The inner bearing shell segment lies on a pitch circle which is arranged concentrically to the outer pitch circle with a radius difference of the thickness of the
Es ist besonders vorteilhaft, wenn die Auslaufenden des Klammerprofils (3) zylindrische Form haben und die Nuten (10, 11) im hakenförmigen Fortsatz (12, 13) einen Umschlingungswinkel von 180 - 210° aufweisen. Damit stellen das innere Lagerschalensegment und das äußere Lagerschalensegment etwa die Form einer halbierten zylinderförmigen Nut dar.It is particularly advantageous if the outlet ends of the clamp profile (3) have a cylindrical shape and the grooves (10, 11) in the hook-shaped extension (12, 13) have a wrap angle of 180-210 °. The inner bearing shell segment and the outer bearing shell segment thus represent approximately the shape of a halved cylindrical groove.
Die an den Stoßenden angedeuteten, abgerundeten Verdickungen (14, 15) sind beim gestreckten Profil als Kontakt- und Stützfläche wirksam. Beim Schwenken des Gelenks dienen sie als Wälzfläche bis zu einem Drehwinkel von max. 20° bezogen auf die Trennlinie zwischen den Strangpreßprofilen (1, 2).The rounded thickenings (14, 15) indicated at the butt ends are effective as a contact and support surface in the elongated profile. When swiveling the joint, they serve as a rolling surface up to a rotation angle of max. 20 ° related to the dividing line between the extruded profiles (1, 2).
An dem, den Verdickungen gegenüberliegenden Enden des Strangpreßprofils befindet sich am Stoßende eine Nut-Zapfenverbindung (16), die gleichzeitig auch als Labyrinthdichtung ausgebildet sein kann. Dieses bewirkt eine Entlastung des Gelenks bei auf die geschlossene Wand seitlich wirkenden Kräften.On the ends of the extruded profile opposite the thickenings there is a groove-pin connection (16) at the butt end, which can also be designed as a labyrinth seal at the same time. This relieves the pressure on the joint when there are forces acting laterally on the closed wall.
In Fig. 2 sind die Strangpreßprofile (1, 2) im zusammengeklappten Zustand dargestellt, wobei die Strangpreßprofile plan aufeinanderliegen, während im gestreckten Zustand (Fig. 3) die Profile (1, 2) einen glatten Abschluß mit der Profilaußenwand bilden.In Fig. 2, the extruded profiles (1, 2) are shown in the collapsed state, the extruded profiles lying flat on one another, while in the stretched state (Fig. 3) the profiles (1, 2) form a smooth finish with the profile outer wall.
In den Figuren 3 und 4 ist ein Gelenk mit rohrförmig ausgebildeten Auslaufenden (29, 30) des Klemmprofils (3) dargestellt. Dadurch kann in besonders günstiger Weise eine Führung des Gelenks und damit des Falttores über seitlich eingesteckte Achsen ermöglicht werden.A joint with tubular outlet ends (29, 30) of the clamping profile (3) is shown in FIGS. 3 and 4. As a result, the joint and thus the folding door can be guided in a particularly favorable manner via axially inserted axes.
Die in den vorstehend beschriebenen Figuren 1 - 4 dargestellten Gelenkverbindungen zeigen ein verbessertes Reibungsverhalten durch Verwendung der erfindungsgemäß ausgebildeten T-förmigen Auslaufenden. Dies bezieht sich einerseits auf den zu erwartenden Verschleiß des Gelenks und andererseits auf den Kraftaufwand bei Betätigung des Gelenks. Zusätzlich wird das klappernde Geräusch bei dem Aufeinanderschlagen von metallischen Flächen vermieden, wenn die in Kontakt stehenden Gelenkteile mindestens einseitig mit Gleitprofilen aus Kunststoff ausgerüstet sind.The joint connections shown in FIGS. 1-4 described above show an improved friction behavior by using the T-shaped outlet ends designed according to the invention. On the one hand, this refers to the expected wear of the joint and, on the other hand, to the effort required to actuate the joint. In addition, the clattering noise when metal surfaces collide is avoided if the articulated parts in contact are equipped with plastic sliding profiles on at least one side.
So ist in Fig. 1 das Klemmprofil (3) mit T-förmig ausgebildeten Auslaufenden (8, 9) dargestellt, die sich auf den zugehörigen Flächen der Strangpreßprofile (1, 2) über entsprechend geformte Kunststoffprofile (18, 19, 38, 39) abstützen.1 shows the clamping profile (3) with T-shaped outlet ends (8, 9), which are located on the associated surfaces of the extruded profiles (1, 2) via correspondingly shaped plastic profiles (18, 19, 38, 39). support.
