Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a radar reflector comprising three planar plates orthogonal to each other.

Collapsible lifeboats, life rafts, and small lifeboats are made of rubber, wood, etc. and are difficult to see by radar. Therefore, it is desirable to equip a radar reflector, but since the boat is foldable or small, it is difficult to store a radar reflector assembled three-dimensionally. The present invention relates to a foldable radar reflector that can be folded into a flat shape for easy storage, and when used in an emergency, can be assembled three-dimensionally in one operation and functions as a radar reflector. The contents of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a side view showing the assembled state of the radar reflector of the present invention, and FIG. 2 is a plan view thereof.
In the figure, 1 is a vertical axis, and four vertical plane plates 2 that can be folded around this axis are provided, and a corner reflector 3 is formed by three orthogonal planes with each plane plate serving as the first plane. A second plane 4 and a third plane 5 are provided respectively, and the main reflection axis 3 thereof is
(indicated by an arrow) is in the horizontal direction, the intersection line of the first plane 2, the second plane 4, and the third plane 5 has an included angle of 90 degrees, and its center line is horizontal, and The intersection line between the second plane 4 and the third plane 5 is formed to be horizontal. Furthermore, the center line 6 of the second plane 4 is formed as a bending line so that it can be bent freely, and each intersection line of the first plane, the second plane, and the third plane is also formed so that it can be bent freely. One end of the drawstring 7 is fixed near the end of the folded line 6 on the second plane, and the other end is attached to the insertion hole 8 at the upper end of the first plane plate 2 facing the folded line.
is inserted and extended upward, and a stopper 9 is fixed just in front of the insertion hole of the drawstring 7. In this way, the corner reflectors 3 are foldably provided on each of the four first plane plates 2 around the vertical axis, but the positions are such that the gathering points 10 of the corner reflectors are at the same position.

Next, to fold, set the second plane to 2 with polygon line 6.
When folded, the third plane is folded so as to overlap the first plane. Next, each first flat plate is bent along the vertical axis 1 and folded so as to overlap. This folded state is shown in FIG. Stored in a folded state in a collapsible lifeboat, life raft, etc.

In case of emergency, to use as a radar reflector, pull the string 7 and the second plane will be pulled by the string and gradually open. FIG. 4 shows the middle of the open state. Next, when the stopper 9 is pulled until it hits, the second plane becomes one plane, and the
Assemble exactly as shown. In this state, if the vertical axis 1 is fixed to a lifeboat or the like using strings 7 and 11 so that it is vertical, the main reflection axes of each corner reflector 3 will be arranged radially in a cross shape in the horizontal direction, and the ship's radar It effectively reflects the light and makes its presence known.

In this embodiment, the outer shape of the corner reflector is arc-shaped, but it may be straight or other shapes. Also, although opening from the folded state was done by pulling the string 7, it may also be done by the elasticity of a spring, etc. .
