Description

Ausleger für Markisen u. dgl. Den Gegenstand der Erfindung bildet ein Ausleger für als Sonnenschutz benutzte Markisen, der sich von derartigen bekannten Einrichtungen dadurch auszeichnet, daß der Auslegerarm mit der Strebe durch eine Feder verbunden ist. Bei Markisenauslegern der vorliegenden Art mit auf einer senkrechten festen Stange gleitendem Führungsstück kommt es bei starken Windstößen oft vor, daß das Auslegerende mit der Markise hochgehoben wird und dann in die senkrechte Lage fällt, wobei oft Beschädigungen des Markisenstoffes vorkommen und die Markise wieder ausgelegt werden muß. Man hatte deshalb schon zu dem Mittel gegriffen, einen Stift unter das Führungsstück zu stecken. Hierbei ergab sich dann oft der Übelstand; daß es vergessen wurde, diesen Stift beim Aufrollen der Markise herauszunehmen, so daß oft der ganze Ausleger verbogen wurde, da das : Aufrollen der Markise infolge der großen Hebelübersetiüng mit- großer Kraftentwickelung erfolgt. .Brackets for awnings and the like forms the subject of the invention a boom for awnings used as sun protection, which is known from such Facilities characterized in that the cantilever arm with the strut by a Spring is connected. With awning arms of the present type with on a vertical fixed rod sliding guide piece, it often occurs in strong gusts of wind, that the boom end is lifted up with the awning and then into the vertical Location falls, with damage to the awning fabric and the awning must be interpreted again. That is why they had already resorted to the means, one To insert the pin under the guide piece. This often gave rise to the problem; that it was forgotten to hold this pen Roll up the awning take out, so that the whole boom was often bent, because that: rolling up the awning takes place with great force development due to the large lever transmission. .

Diese Nachteile werden nun nach der -Erfindung durch Anordnung einer Schraubenfeder zwischen dem Ausleger und der Haltestrebe vermieden. Durch die an einem kurzen Hebelarm der Strebe und am Ende des Auslegers angreifende Feder wird der Ausleger in beiden Endlagen, also ausgelegt wie auch hochgeklappt, in seiner Lage gehalten, so daß kein unbeabsichtigtes Auf- oder Zuklappen der Markise erfolgen kann.These disadvantages are now after the invention by arranging a Helical spring between the boom and the retaining strut avoided. Through the at a short lever arm of the strut and spring acting at the end of the boom the boom in both end positions, so laid out as well as folded up, in his Held in position so that the awning cannot be opened or closed inadvertently can.

In der Zeichnung ist die Erfindung dargestellt, und zwar zeigt Abb. i eine Seitenansicht des ausgeklappten Auslegers, Abb. z eine Vorderansicht des hochgeklappten Auslegers.The invention is shown in the drawing, namely Fig. i a side view of the extended boom, Fig. z a front view of the folded up boom.

Der Auslegerarm u ist zweckmäßig an dem einen Ende zur Aufnahme und zum Verdecken der Feder b U-förmig ausgebildet und gleitet mit dem Führungsrohrstück c auf der festen Stange d. Die Feder b hält den Ausleger a sowohl in der ausliegenden wie auch in der hocbgeklappten Lage, da die Angriffspunkte der Feder b an -der Strebe e wie am Auslegerarm a so gewählt sind, daß in beiden Lagen die Feder b entspannt ist und die Feder gegen jede Änderung dieser Lagen wirkt, so daß beim Übergang von der einen Lage in die andere der Federwiderstand überwunden werden muß.The cantilever arm u is expediently U-shaped at one end for receiving and concealing the spring b and slides with the guide tube piece c on the fixed rod d. The spring b holds the boom a both in the open position and in the hocbgeklappten position, since the points of application of the spring b on the strut e and on the boom a are chosen so that the spring b is relaxed in both positions and the spring against every change in these positions has an effect, so that the spring resistance must be overcome when moving from one position to the other.
