Abstract

The chromium-plated surfaces (1) are held together by flexible hinges (2). The surfaces are stabilised by edges (3) of special shape. The bottom surface (1a) forms a container which surrounds the surfaces after their folding down. The container walls (4) lock the erected surfaces at a required angle. The folded configuration is safeguarded by a cord (5) which is provided with slide knots neat the safety eyelets (6) during packaging. By pulling the cord the radar reflector is erected and secured. The reflector elements may be also of metal, or other material, such as a textile fabric with metallising foil.

Ein*Radar-Reflektor für Rettungs-Flöße u. -Boote ist Gegenstand der Erfindung.A * radar reflector for life rafts and boats is the subject of the Invention.

Radar-Reflektoren werden in der Schiffahrt eingesetzt um schlecht zu ortende Objekte radarauffaßbar zu machen.Radar reflectors are used in shipping around badly to make objects to be located radar detectable.

Das Deutsche Hydrographische Institut hat mit Baumusterprüfnummern verschiedene Typen zugelassen. Diese haben alle eine Größe von rd. 50 cm und müssen fest installiert werden.The German Hydrographic Institute has type approval numbers different types approved. These all have a size of around 50 cm and must be permanently installed.

Aufblasbare Rettungsflöße, international zugelassene Rettungsgeräte, führen bisher keine Radar-Reflektoren.Inflatable life rafts, internationally approved rescue equipment, have not yet carried any radar reflectors.

Aus dünnem, gummierten Textil hergestellt, werden die Rettungsflöße in GZK-Containern klein verpackt, bekannte Radar-Reflektoren können wegen ihrer starren Bauausführung und Größe nicht mit verpackt werden.The life rafts are made from thin, rubberized textile Packed small in GZK containers, known radar reflectors can because of their rigid construction and size are not included in the packaging.

Im Seenoteinsatz gibt das Rettungsfloß aus Textil absolut kein Radar-Echo, seine schnelle Radarortung ist aber wichtig, um Menschen zu retten.The textile liferaft emits absolutely no radar echo in emergency operations, however, its rapid radar location is important in order to save people.

Der Erfindungsgegenstand, ausschließlich für Rettungsflöße konstruiert, ist ein Radar-Reflektor in Form eines Tripelspiegels, viertelkreisförmig, mit der baumustergeforderten Kantenlänge.The subject of the invention, designed exclusively for life rafts, is a radar reflector in the form of a triple mirror, quarter-circle, with the edge length required by type.

Er ist faltbar und klein verpackbar.It is foldable and packs up small.

Die Zeichnung zeigt: Fig. I den gefalteten Radar-Reflektor Fig. II die Funktionsstellung des Radar-Reflektors Die Flächen (1) sind miteinander und mit der Bodenfläche (la) durch elastische Scharniere verbunden und faltbar.The drawing shows: Fig. I the folded radar reflector Fig. II the functional position of the radar reflector The surfaces (1) are with each other and connected to the bottom surface (la) by elastic hinges and foldable.

Die Flächen (1) sind stabilisiert durch Abkantung (3).The surfaces (1) are stabilized by a fold (3).

Die Bodenfläche (la) ist als Behälter ausgebildet, wobei die Wände (4) die Einhaltung der geforderten Winkelgenauigkeit im aufgefalteten Zustand gewährleisten.The bottom surface (la) is designed as a container, with the walls (4) Ensure compliance with the required angular accuracy in the unfolded state.

Beim Einfalten der Flächen (1) in den Behälter (la) kommen die elastischen Scharniere (2) unter Vorspannung.When the surfaces (1) are folded into the container (la), the elastic ones come Hinges (2) under tension.

Ein willkürliches Auffalten verhindert die Heißleine (5), die beim Verpacken mit Slipknoten durch die Sicherungsöse (6) belegt wird.The hot cord (5) prevents it from being unfolded at will Packing with slip knots is occupied by the securing eye (6).

Durch die Bohrungen (7) werden Verbindungselemente aus Eunststoff geführt, mit denen der Radar-Reflektor am Dach oder Rumpf des Rettungsfloßes befestigt wird, während die Heißleine durch eine Schottdurchführung in das Innere des Rettungsfloßes führt.Fastening elements made of plastic are placed through the bores (7) out with which the radar reflector is attached to the roof or hull of the liferaft will while the hot cord through a bulkhead duct into the Interior of liferaft leads.

Mit Ziehen der Heißleine (5) wird der Radar-Reflektor in Funktionsstellung gebracht.When the hot cord (5) is pulled, the radar reflector is in the functional position brought.

Die Handhabung ist einfach.It is easy to use.

Der Radar-Reflektor ist aus verchrom-tem Kunststoff gefertigt, temperaturbeständig von -400 bis +900 und enthält keinerlei Metallteile.The radar reflector is made of chrome-plated plastic and is temperature-resistant from -400 to +900 and does not contain any metal parts.

Er ist korrosionssicher und leicht.It is corrosion-proof and light.
