Description
Die Erfindung geht aus von einem Winkelstück für die Verbindung der Längs- und Querstreben eines dreiteiligen Stützrahmens, welcher etwa die Form eines umgekehrten U aufweist, insbesondere als bogenförmige Stütze für faltbare Sonnenschutzblenden, Verdecke, Markisen, Schutzdächer von Gerüsten od. dgl.The invention is based on an elbow for connecting the Longitudinal and transverse struts of a three-part support frame, which is roughly the shape of a has an inverted U, in particular as an arched support for foldable sunshades, Canopies, awnings, canopies of scaffolding or the like.
Bei der Herstellung und Montage derartiger Stützrahmen ergeben sich mitunter beachtliche Schwierigkeiten, insbesondere wenn diese aus miteinander zu verbindenden Längs- und Querstreben bestehen und die Querstreben verhältnismäßig lang sind. Hierbei ist es erforderlich, ein Durchbiegen dieser Querstreben zu verhindern, welches durch eine beträchtliche Länge der Querstrebe und deren Gewicht sowie auch bei einer bestimmten Belastung eintreten kann. Diese Deformationen der Querstrebe sind besonders ausgeprägt, wenn diese eine sehr große Länge aufweisen.In the manufacture and assembly of such support frames arise sometimes considerable difficulties, especially when these are out with each other connecting longitudinal and transverse struts and the cross struts are proportionate are long. It is necessary to prevent these cross braces from bending, which by a considerable length of the cross brace and its weight as well can occur at a certain load. These deformations of the cross brace are particularly pronounced when they are very long.
Zur Vermeidung dieser Durchbiegung der Querstreben ist es bekannt, diese vor ihrer Montage zu verformen und ihnen eine Gegenkrümmung zu verleihen, was jedoch einen zusätzlichen Arbeitsgang bei der Herstellung eines Stützrahmens erfordert.To avoid this deflection of the cross struts, it is known to deform them before their assembly and to give them a counter-curvature, however, which is an additional operation in the manufacture of a support frame requires.
Eine andere Möglichkeit zur Vermeidung des Durchbiegens einer Querstrebe besteht darin, ihren Querschnitt zu vergrößert, was jedoch gleichzeitig eine Erhöhung des Gewichtes und des Materialverbrauches bedingt sowie auch in den meisten Fällen wenig wirkungsvoll ist.Another way to avoid bending a cross brace consists in increasing its cross-section, which, however, at the same time increases it the weight and the material consumption conditionally as well as in most cases is ineffective.
Es wurde auch schon versucht, eine Durchbiegung der Querstrebe durch die Anordnung einer Verspannung zwischen dem Stützrahmen zu verhindern, welche der Querstrebe eine der Belastung entgegengesetzte, nach außen gerichtete Krümmung verleiht. Diese Lösung ist jedoch nicht sehr praktisch und kann in vielen Fällen ebenfalls wirkungslos sein.Attempts have also been made to prevent the cross brace from bending to prevent the arrangement of tension between the support frame, which of the Cross brace gives an outward curvature opposite to the load. However, this solution is not very practical and in many cases it can as well be ineffective.
Neben der Verhinderung einer Durchbiegung der Querstrebe werden die vorstehend erwähnten Verfahren und Anordnungen vcr allem auch deswegen vorgesehen, um einer mit einem Stützrahmen versehenen Blende, einer Markise od. dgl. eine nach außen gewölbte Form zu geben, wodurch ein gefälliger Anblick erzielt wird. Wie erwähnt, sind jedoch diese bekannten Verfahren und Anordnungen wenig zu- , friedenstellend.In addition to preventing the cross brace from bending, the The above-mentioned procedures and arrangements are mainly intended to around a cover provided with a support frame, an awning or the like to give a curved shape on the outside, whereby a pleasing appearance is achieved. As mentioned, however, these known methods and arrangements are unsatisfactory.
Die Aufgabe der Erfindung besteht darin, Winkelstücke der im ersten Absatz der Beschreibung genannten Art insoweit zu verbessern, daß in einfacher Weise sowohl eine Durchbiegung der Querstrebe verhindert und eine mehr oder weniger ausgeprägte Wölbung der Querstrebe nach außen erhalten werden kann.The object of the invention is to provide elbows in the first Paragraph of the description mentioned type to improve that in a simple manner both a deflection of the cross brace is prevented and a more or less pronounced one Outward curvature of the cross brace can be obtained.
Hierzu ist ein solches Winkelstück erfindungsgemäß dadurch gekennzeichnet, daß die mit der Längsstrebe und der Querstrebe verbundenen Schenkel des Winkelstückes einen Winkel von etwas mehr als 90° einschließen.For this purpose, such an angle piece is characterized according to the invention that the legs of the angle piece connected to the longitudinal strut and the cross strut Include an angle of slightly more than 90 °.
Bei dieser Aufgabenlösung sind folgende an sich bekannte Gestaltungsmerkmale benutzt: Es ist bei einem Lagerböckchen für Sonnenblenden bekanntgeworden, den abgewinkelten Tragarm so auszuführen, daß dessen abgewinkelter Teil mit dem Hauptteil einen Winkel einschließt, der mehr als 90° beträgt.In solving this problem, the following design features are known per se used: It has become known for a bearing block for sun visors, the angled Carry out support arm so that its angled part forms an angle with the main part includes which is more than 90 °.
Auf diese Weise kann eine gradlinige Querstrebe verwendet werden, die länger als die Längsstreben ist und die nach Zusammensetzen des Stützrahmens unter Spannung zwischen den Längsstreben sitzt und hierbei eine gleichmäßige, nach außen gerichtete Krümmung erhalten kann.In this way, a straight cross brace can be used, which is longer than the longitudinal struts and which is after assembling the support frame sits under tension between the longitudinal struts and here a uniform, after can get outward curvature.
Der Winkel der Schenkel des erfindungsgemäßen Winkelstückes kann hierbei selbstverständlich je nach der Länge der Querstrebe und der gewünschten Form bzw. Krümmung in gewissen Grenzen variieren.The angle of the legs of the angle piece according to the invention can here of course, depending on the length of the cross brace and the desired shape or shape. Vary curvature within certain limits.
Die Erfindung wird an Hand eines Ausführungsbeispieles im Zusammenhang mit der Zeichnung näher erläutert.The invention is illustrated in the context of an exemplary embodiment explained in more detail with the drawing.
Aus der Zeichnung ist das Winkelstück 3 für die Verbindung der Längsstreben 1 und Querstreben 2 eines dreiteiligen Stützrahmens, welcher etwa die Fcrm eines umgekehrten U aufweist, insbesondere als bogenförmige Stütze für faltbare Sonnenschutzblenden, Verdecke, Markisen, Schutzdächer von Gerüsten od. dgl. zu erkennen.From the drawing is the angle piece 3 for connecting the longitudinal struts 1 and cross struts 2 of a three-part support frame, which has about the Fcrm of a has an inverted U, in particular as an arched support for foldable sunshades, Canopies, awnings, canopies of scaffolding or the like. To recognize.
Die Schenkel 4, 5 des Winkelstückes 3 schließen einen Winkel von mehr als 90° ein.The legs 4, 5 of the elbow 3 close an angle of more than 90 °.
