DE3026849A1 - Rescue aid for shipwreck - has reflecting kite with inflated sections - Google Patents

Abstract

The shipwreck rescue aid has a self inflating shape tied to the survivor as a kite and coated with reflecting material for optical- and radar identification. The shape is delta to provide aerodynamic lift even in high winds. The delta shape has several sections each independently inflated with a lighter than air gas. The securing ties hold the shape in correct attitude for flight and provide better lift than a mere balloon shape.

Description

Optical guidance for shipwrecked people

The invention relates to a device for displaying accidents with at least one, in the event of an accident automatically or automatically with one gas lower density than air-inflatable balloon that is directly or indirectly connected to the Casualty is connected by a leash or the like.

The optical locating aid for shipwrecked people is supposed to be shipwrecked give an increased chance, even in strong winds or storms and high waves to be located quickly.

In the laid-open specification DE 28 48 067 Al, the problem of the optical Visualization of the shipwrecked with a balloon, which although with a gas can be filled but has no aerodynamic lift.

Serious emergencies at sea in which shipwrecked people drift in open water, usually occur in strong winds or storms, where a balloon does not have its own aerodynamic buoyancy generated, pressed by the wind onto the water and thus becomes ineffective.

The invention is based on the object that locations of shipwrecked people To safely accelerate and simplify this in all wind and weather conditions The task is with a device of the type mentioned, wherein the balloon may consist of individual hollow body sections which are shaped in such a way that when air flows against it, a buoyancy effect arises, according to the invention solved that the hollow body sections from separately, manually or automatically, inflatable Elements that have an optically reflective or metallic or metallized material are connected in such a way that after the type of wings one Oeltadrachens aerodynamic lift surfaces arise, further developments of the invention emerge from the subclaims.

An exemplary embodiment of the invention is shown in the drawing and is described in more detail below.

The Hohlkdrperabschnitte (1), each other with an optically reflective or metallic or metallized film (2) are connected, run together at the upper end in one of the line attachment points (5).

At the lower end of the hollow body sections (1), the optically reflective or metallic or metallized foil stripes (a), which contribute to flight stability contribute and also represent an additional visible surface.

The expansion chambers (3), each with the outer hollow body sections (1) can be connected to ensure that the missile is at its full size is spread. However, if the wind is too strong on the missile, you can bend away the expansion chambers (3) and thus reduce the area exposed to wind the buoyancy effect is maintained.

The number of line attachment points (5) depends on the size of the Missile nb.

With the steering lines (6), in connection with the line attachment score (5), the missile is held at a certain angle to the wind.

Should one or a maximum of two of the hollow body sections (1) be mechanically be defective, the remaining hollow body section (1) would still have buoyancy by touching it with air, which results in a high level of functional reliability is guaranteed.

The missile "dancing" at a certain height above the surface of the water can be a distress signal that can be seen from afar for rescue teams.

Through the metallic or metallized surface of the missile there is: also the possibility of locating the river by wheels.
