Abstract

A drag reducer (a) for the front of a caravan or trailer comprises a tubular frame assembled into a streamlined shape and covered with a flexible cover. It extends the front end of the trailer and reduces the drag. The frame is made from lightweight telescopic sections linked by corner pieces. It is simple to assemble and can also be used to erect a sun shade for the car or a porch for the caravan. A smaller type can be used to streamline a roofrack.

Description

Beschreibung Vorrichtung für Wohinanhänger,LKW's und Gepäckträger zur Verbesserung der aerodynamischen Fahreingenschaften.Description Device for trailers, trucks and luggage carriers to improve the aerodynamic driving characteristics.

Es ist bekannt,daß gezogene Hnhänger,wie Wohnwagen,kastenförmige LKW's und Gepäckträger wegen ihrer heträchtlichen Windangrifsflächen die Fahreingenschaften negativ beeinflussen: höherer Treibstoffverbrauch und Instabilität.It is known that towed trailers, such as caravans, box-shaped trucks and luggage racks because of their considerable wind attack surfaces negatively affect: higher fuel consumption and instability.

Die Erfindung bezieht sich auf eine Vorrichtung, die durch Anbau'auch nachträglich'das Profil des Anhängers,des LKW-Kastens oder das Gepäckträgergerüst's an PKW's, aerodynamisch verändert. (Abb. 1 a,b,c ; 2 a1, a2, b, c ; 3 d,e ) Dies wird dadurch erreicht,daß ein rohrartiger Rahmen mit geeigneter Keilform an den Bug des Anhängers,LKW Kasten Front oder das Gepäckträgergerdst montiert wird.tAbb. 4 5;6;7) Dieser Rahmen dient als Stütze für eine elastiche Plane, welche mit Befestigungselementen,wie Drehkreuz und Reißverschlußelemente'an den Seitenkanten versehen sind'und somit die gewünschte aerodynamischen Form erhalten wird.The invention relates to a device that by cultivation'auch retrospectively: the profile of the trailer, the truck box or the luggage rack frame on cars, aerodynamically modified. (Fig. 1 a, b, c; 2 a1, a2, b, c; 3 d, e) this is achieved in that a tubular frame with a suitable wedge shape to the The front of the trailer, the front of the truck box or the luggage rack is mounted. 4 5; 6; 7) This frame serves as a support for an elastic tarpaulin, which with fastening elements, such as Turnstile and zipper elements are provided on the side edges and thus the desired aerodynamic shape is obtained.

(abb. 4 ; 5 ; 6 ;) Die Spannvorrichtung und die Plane sind so gestaltet,daß eine windschnittige Ausbuchtung in Richtung nach vorn in Fahrtrichtung entsteht.tAbb. 1 ; 2 ; 3 3 ) Die Spannvorrichtung ist über Halterung mit der Bugvorderwand des Wohnanhängers,LK'#-Kasten,Gepäckträgeryerüstes mit scharnierartige Steckverbindung fest verbunden.(Abb. 4h ; 5h; 6r;?s) Je nach äußerer Form der Wohnanhänger, LKW's oder Gepäckträger,kann die Vorrichtung zum nachträglichen Anbau zur Verbesserung der aerodynamischen Fahreingenschaften formmäßig angepaßt werden.(bb. 1 ; 2 ; 3 3 ) Der technische Fortschritt dieser Vorrichtung zur Veri-le-iserung der aerodynamischen Fahreingenschaften ist gekennzeichnet wie folgt a - Nachträglichen Anbau b - Verbesserte Windschlüpfikeit und Spurtreue des Fahrzeuges.(Fig. 4; 5; 6;) The tensioning device and the tarpaulin are designed so that a streamlined bulge is created towards the front in the direction of travel. 1 ; 2; 3 3) The clamping device is attached to the front wall of the Caravan, LK '# box, luggage rack frame with hinge-like plug connection firmly connected. (Fig. 4h; 5h; 6r;? s) Depending on the external shape of the caravan, truck or luggage rack, the device can be retrofitted to improve the shape of the aerodynamic driving characteristics (fig. 1; 2; 3 3) The technical progress of this device for veri-le-izing the aerodynamic Driving characteristics is marked as follows a - Subsequent attachment b - Improved Wind slip and directional stability of the vehicle.

c - Reduzierter Kraftstoffverbrauch.c - Reduced fuel consumption.
