Abstract

The tensioning struts are located between the slide (7) moving on the stock of an umbrella, and the umbrella ribs (5). The lower section (1) of a strut guides a spiral spring (3), which is suspended from the slide (7), approx. 2cm below the strut, and from the upper end of a strut, to stabilize it and hold it in position. It simultaneously supports the opening mechanism of the umbrella. The upper section (2) of a strut is fastened via joints (4) to the lower section and to a sleeve (6) fixed to the ribs.

Description

Bei herkömmlichen Schirmen sind sowohl Spannstreben, als auch Schirmrippen überwiegend aus Metall gefertigt und über verschiedene Gelenke miteinander verbunden. Dadurch bleibt die ganze Konstruktion relativ statisch, die mangelnde Flexibilität führt bei starkem Wind und dem dabei oft auftretenden Umschlagen des Schirms häufig zu Defekten, bzw. muss der Schirm umständlich wieder in die richtige Lage gebracht werden. Kompliziertere Gelenkkonstruktionen erhöhen zwar die Beweglichkeit (nicht unbedingt die Handlichkeit), gleichzeitig vermindern sie aber die Festigkeit des Schirms als Ganzes und schaffen neue potentielle Defektstellen.With conventional umbrellas, both struts, as well as screen ribs predominantly Made of metal and over different joints connected together. This keeps the whole construction relatively static, the lack of flexibility leads to strong winds and often occurring folds of the screen to defects, or must the umbrella awkward be put back in the right position. More complicated joint designs increase mobility (not necessarily handiness), at the same time but they reduce the strength of the umbrella as a whole and create new potential defects.

Es stand also die Aufgabe, eine Konstruktion zu finden, die den ganzen Schirm ohne Verlust von Stabilität flexibler und elastischer macht, um so die Defektanfälligkeit zu mindern. Dabei sollten weder Handlichkeit noch Beweglichkeit leiden und außerdem durch eine möglichst einfache Lösung Gewicht und Herstellungsaufwand gering gehalten werden.So it was the task of a construction find the whole screen more flexible without loss of stability and makes it more elastic so as to reduce the susceptibility to defects. there should suffer neither handiness nor mobility and also by one if possible simple solution Weight and manufacturing costs are kept low.

Diese Anforderungen können durch die spezielle Konstruktion der Spannstreben (siehe Schutzanspruch 1) in Verbindung mit Schirmrippen aus Kunststoff erfüllt werden. Eine größere Elastizität wird dann durch die Feder (3), in Verbindung mit den Schirmrippen (5) erreicht. Im aufgespannten Zustand sind die Schirmrippen durch die Spannstreben vorgespannt und können so dem Umschlagen ausreichend Widerstand entgegensetzen ( I). Sollte dies dennoch passieren, so bleibt die untere Strebe (1) durch die Feder in ihrer Position, während gleichzeitig die obere Strebe (2) und die Gelenke (4) eine bewegliche aber stabile Verbindung zu den Schirmrippen gewährleisten (II).These requirements can be met by the special construction of the struts (see protection claim 1) in connection with plastic screen ribs. The spring is then more elastic ( 3 ), in connection with the screen ribs ( 5 ) reached. In the open state, the screen ribs are pre-tensioned by the tension struts and can therefore offer sufficient resistance to the change ( I ). Should this happen anyway, the lower strut ( 1 ) in position by the spring, while at the same time the upper strut ( 2 ) and the joints ( 4 ) ensure a flexible but stable connection to the shield ribs ( II ).

Zum Zurückklappen des Schirms braucht lediglich der Schlitten nach unten gezogen zu werden (III), wobei die Spannstreben die Schirmrippen wieder in ihre alte Lage ziehen. Die Handhabung ist einfach und die elastischen, zusammen mit den beweglichen Teilen verarbeiten die beim Umschlagen des Schirms auftretenden Kräfte besser. Die Kontrolle des Schirms wird erleichtert und die Defektanfälligkeit gesenkt.All you need to do to pull the umbrella back down is to pull the slide down ( III ), whereby the tension struts pull the shield ribs back into their old position. The handling is easy and the elastic, together with the moving parts, better handle the forces that occur when the umbrella is turned. The control of the screen is facilitated and the susceptibility to defects is reduced.
