Der Erfindung liegt daher das technische Problem zugrunde, eine verbesserte Vorrichtung zum Stauen und Entfalten von Foliensystemen zu schaffen, die ohne aktive Hilfsmittel wie beispielsweise Motoren auskommt.Of the The invention is therefore based on the technical problem, an improved To provide a device for jamming and unfolding of film systems, which works without active aids such as motors.
Die Lösung des technischen Problems ergibt sich aus dem Gegenstand mit den Merkmalen des Patentanspruchs 1.The solution the technical problem arises from the subject with the Features of claim 1.
Dazu wird die Folie an elastischen Spannmasten befestigt, die tangential an einem Basismodul verankert sind. Zum Stauen werden die Spannmasten eng um das Basismodul gewickelt und in der aufgewickelten Stellung arretiert. Zum Entfalten der Folie wird die Arretierung gelöst. Da die Spannmasten elastisch sind, schwingen sie allein aufgrund ihrer Formänderungsenergie in ihre ursprüngliche Lage zurück und spannen so die Folie auf. Das Entfalten allein durch die Formänderungsenergie hat dabei den Vorteil, dass kein Fremdantrieb und damit keine Energieversorgung benötigt wird. Ein weiterer Vorteil besteht in der hohen Zuverlässigkeit des Systems, was vor allem im Weltraum, wo kein Techniker zum Beheben von Problemen zur Verfügung steht, von besonderer Bedeutung ist.To the film is attached to elastic tension masts which are tangential anchored to a base module. To stow the tension masts wrapped tightly around the base module and in the wound position locked. To unfold the film, the lock is released. Because the Tension masts are elastic, they swing alone due to their strain energy in their original one Location back and so tighten the film. The unfolding solely by the strain energy has the advantage that no external drive and thus no energy supply needed becomes. Another advantage is the high reliability of the system, especially in space, where no technician can fix it of problems available is of particular importance.
Dabei sind zwischen dem Basismodul und den Spannmasten Spannfäden gespannt. Diese Spannfäden haben die Aufgabe, beim Entfalten ein Überschwingen der Spannmasten und damit eine mögliche Beschädigung der Folie zu verhindern. Des weiteren verleihen die Spannfäden der Struktur zusätzliche Stabilität.there Tension threads are stretched between the base module and the tension masts. These tensioning threads have the task of unfolding an over-swinging of the tension masts and thus a possible damage to prevent the film. Furthermore, the tensioning threads give the Structure additional Stability.
Weiter sind zwischen verschiedenen Spannmasten Begrenzungsfäden gespannt. Auch die Begrenzungsfäden haben die Funktion, ein Überschwingen der Spannmasten zu verhindern und die Stabilität der Struktur zu erhöhen.Further are stretched between different clamping masts limiting threads. Also the boundary threads have the function of overshooting to prevent the tension masts and to increase the stability of the structure.
Bevorzugte Anwendungsfälle der Erfindung sind insbesondere Antennen, Sonnensegel, Solarpaneele oder Vorrichtungen zum Sonnenschutz.preferred use cases The invention relates in particular to antennas, solar sails, solar panels or sun protection devices.
Die Erfindung wird im folgenden anhand eines bevorzugten Ausführungsbeispiels näher beschrieben. Die Fig. zeigen:The Invention will be described below with reference to a preferred embodiment described in more detail. The figures show:
