Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Ships are designed for safe navigation.
Ship rescue aids are required by the Ship Safety Act, Ship Equipment Regulations, Small Ship Safety Regulations, etc. It is obligatory to provide a balloon called a black sphere with a diameter of 600 mm or more to notify that it is impossible to open the course to the ship, and to equip a small ship with a polyhedral radar reflector with radar reflection function . The present invention relates to a ship rescue device combining the black ball and a radar reflector.

[0002]

2. Description of the Related Art Conventionally, a black sphere (see FIG. 5) and a radar reflector (see FIG. 4) are separately provided on a ship, and the radar reflector is a plate made of a hard material having a radar reflection function. Were assembled so that the faces were orthogonal to each other to form a polyhedron, and fixed to the bow or mast of the ship before sailing.

[0003]

In the conventional radar reflector, the plate assembly is not easy to assemble and it takes time and effort, and it takes up space in the ship when not in use, especially in a narrow ship of a small ship. There is a problem in that assembling or assembling on board the ship as required violates the iron rules of "simple", "simple", "light", and "compact" in maneuvering.

[0004] It is an object of the present invention to solve the above-mentioned problems, and an object of the present invention is to provide a ship rescue device that solves the problems.

[0005]

In order to achieve the above-mentioned object, according to the present invention, there is provided a foldable support which is filled with air to expand into a spherical shape, and a foldable plurality of supports. A reflector body having a radar reflection function in which the plurality of surfaces are formed three-dimensionally by pulling edges outward, and the edges are connected to the inner surface of the support, and a folding body. And a black black sphere formed so as to cover the outside of the support.

According to another aspect of the present invention, there is provided a foldable support which expands into a spherical shape by filling air therein, and three foldable squares coated with a material having radar reflection characteristics. Each of the fabrics is crossed so that the surfaces are orthogonal to each other, and each corner of each of the fabrics is provided with a reflector body cooperating with the inner surface of the support, a foldable, openable and closable opening / closing unit, And a black black sphere formed so as to cover the outside.

[0007]

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. Here, FIG. 1 of the accompanying drawings is a perspective view, FIG. 2 is a perspective view showing a black sphere and a support body cut away to show the inside, FIG.
Is a perspective view of a conventional reflector, and FIG. 5 is a perspective view of a conventional black ball.

A rescue device 1 for a ship comprises a support 2 which is foldable and expands in a spherical shape by being filled with air.
And three rectangular fabrics 3 which are foldable and coated with a material having radar reflection characteristics, are crossed so that their respective center lines cross each other so that each surface is orthogonal to each other. The reflector 4 has a portion 4 attached to the inner surface of the support 2 and a foldable attachment string 6.
A black black sphere having a plurality of fixtures 7 for fixing the outer surface thereof, formed so as to cover the outside of the support body 2, and provided with an opening / closing portion 8 which can be opened and closed so that the covering can be easily performed. 9.

As shown in FIGS. 1 and 3, the support 2 is
It is made of a foldable soft resin sheet and has an air inlet 10 for filling air. The air supply port 10 has a cylindrical shape slightly protruding outward, and is configured so that the inside can be sealed from the outside by fitting a plug 10a connected to the cylindrical portion.

As shown in FIGS. 1 to 3, a reflector main body 5 is provided with a coating agent containing nickel and a polyester coating material.
A plurality of surfaces formed by each of the fabrics 3 can efficiently reflect the radar. A fixing cord 4a is provided at each of the four corners 4 of each of the cloths 3, and the tip of each fixing cord 4a is fixed to an adhesive plate 4b attached to the inner surface of the support 2. Reflector body 5 configured in this manner
When the air is filled into the support 2 through the air supply port 10 during use, the support 2 is expanded and the respective corners 4 are pulled outward by the inner surface of the support 2 and extended. Then, each fabric 3 forms 24 three-dimensional reflecting surfaces orthogonal to each other.

As shown in FIGS. 1 to 3, the black sphere 9 is made of a foldable black flexible sheet, and is formed so as to be substantially spherical so as to cover the support 2 in an expanded state. . The black sphere 9 is provided with a notch 11 at a portion corresponding to the charging port 10 of the support 2 when the black sphere 9 is put on the support 2, and the opening and closing portion 8 reaching the opposite side from the edge of the notch 11. The opening and closing part 8 is provided with a fastener 8a.
It is configured to open and close. Further, a holding member 1 for fixing an air supply pipe 12 of an air pump for sending air into the support 2 is provided on an outer surface adjacent to the notch 11.
3 is provided.

A method of using the marine rescue device 1 configured as described above will be described. First, when the ship cannot be steered or in distress, with the support 2 covered with the black spheres 9, the tip of the air inlet pipe 12 of a manual air pump (not shown) is connected to the black spheres 9.
Through the holding member 13 and fitted into the charging port 10. continue,
The support 2 is filled with air from an air pump, and the fastener 8a is closed when the support 2 expands. When the support 2 expands in this manner, each corner 4 of the reflector main body 5 inside the support 2 is pulled outward, and the reflector main body 5 has 24 surfaces that efficiently reflect radar by the action of a reflector. Deforms into something with a reflective surface. Further, since the rescue equipment 1 for a ship is covered with the black sphere 9, it can be used as a conventional black sphere. This ship rescue equipment 1
Is attached to the bow or the like as necessary with the attachment cord 6 tied to the fixture 7, and has the advantage that the functions of the conventional black ball and the conventional reflector can be exhibited as one tool. The reflector can be formed simply by inflating it, and it can be folded in normal times, so that it has the advantage of taking up little space, conforming to the rules of maneuvering, and being preferred as a tool for ships.

The present invention is not limited to the above embodiment. For example, when the reflector body 5 crosses each of the three rectangular fabrics 3 in a grid pattern, it does not cross the center line. Alternatively, each diagonal may be crossed. In this case, the two corners of each cloth 3 to be intersected are connected as a set to each of the adhesive plates 4b. Further, in order to fill the support 2 with air, a person may inhale without using a pump.

[0014]

As described above, according to the present invention described in claim 1, the functions of the conventional black sphere and the conventional reflector can be exhibited as one tool, and the reflector can be formed only by expanding the support. It can be folded in normal times, so that there is no space requirement.

According to a second aspect of the present invention, in addition to the effects of the first aspect, the black sphere is provided with an opening which can be opened and closed, so that the support is covered with the black sphere. It is easy to assemble in a narrow ship.
