Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a top mark for a buoy that indicates the starboard and port side route markings, obstacles, etc., and direction indicators relative to the buoy position, and a device for attaching it to the buoy.

A single top mark for a buoy has an outer shape of a triangular pyramid, a cylinder, or a sphere, and one or two of these are attached to the top of the buoy. Therefore, in order to maintain the stability of the buoy, it must be as light as possible, the top mark must be easy to replace depending on the location where the buoy is installed, and the mounting hardware must be usable for any top mark. This invention relates to the invention of a top mark for a buoy that takes into consideration the fact that it is interchangeable, has a small number of types, and that the top mark itself and mounting hardware are lightweight and free from damage. The details will be explained below with reference to the drawings.

FIG. 1 shows a single top mark according to an embodiment of the present invention, which has a thin structure made of foamed polyethylene, and has a member 2 having a central hole 1 for passing the core rod through the center.
The outer skin 3 has a relatively thin outer skin structure, and is a thin single piece structure made of foamed polyethylene, which is connected and reinforced with the outer skin, a member 2 having a center hole, and four horizontal reinforcing plates. Figure 1a is a sphere, Figure 1b is a cone,
Figure c is a partially cutaway front sectional view of the top mark of the cylindrical body. Figures 1d, e and f are cross-sectional views taken along line A in Figures 1a, b and c, respectively, and Figures 1g and h are plan views of Figures 1a and c, respectively. Figure 2 is a detailed view of the top mark of the cylindrical body, which is manufactured in half by cutting along a plane that includes the center line of the core rod through hole.
The cut surface (adhesive surface 5) is heat-bonded to form a single top mark.

FIG. 3 is a bottom view of the cylindrical body (half body), in which the member 2 having the center hole 1 is formed into a plate shape with a plane perpendicular to the adhesive surface 5, and several lightening holes 7 are bored therein. It's dripping. A hole 6 is bored at the lower end of the member 2, into which a rotation stopper plate to be described later is inserted. In addition, a part of the inner surface of the cylindrical outer skin near the adhesive surface 5 is formed into a planar shape perpendicular to the adhesive surface 5, which serves to expand the adhesive area with the other half of the outer skin and to reinforce the outer skin. . Figures 2 and 3 show the details of the top mark of the cylindrical body, but the other spheres and cones are also manufactured in half and then heat bonded.The structure of member 2 and the rotation stopper is that of the cylindrical body. It is similar to

By making the member 2 with the center hole 1 into a flat plate and dividing it into two halves, it is easier to cut out the die during manufacturing, making it possible to manufacture a thin one-piece top mark, and making the top mark lighter. We were able to achieve this goal. Also, since it is made of foamed polyethylene, it is highly elastic and has a thin wall, so even if it hits an object, it will only temporarily dent, but will recover quickly and will not be damaged. In this way, it is an economical single top mark that is extremely lightweight and has no fear of breakage.

FIG. 4a shows the state in which the conical top mark is attached to the core rod 8 for single attachment. A frame mounting flange 9 is attached to the lower end of the core rod 8 by welding or the like, and a top mark receiving plate 9' is attached to the core rod 8 by welding, passing through the top mark receiving plate 9' slightly above the flange 9. A rotation stopper plate 10 is attached to the upper surface of the receiving plate 9', but it may also be fixed to the core rod 8. A plurality of mounting bolt holes 11 are provided in the frame mounting flange 9 as shown in FIG. 4b. The core rod 8 protrudes above the top mark, a ring-shaped presser plate 12 is inserted through the core rod, and a cotter pin is inserted into the pin hole 13 of the core rod to fix the presser plate to the core rod 8 so that it does not lift up. has been done. The lower surface of the holding plate 12 is in contact with the upper surface of the top mark, and holds the top mark together with the receiving plate 9'.

FIG. 5 shows a case in which a set of two conical top marks is installed. The lower top mark is the same as in Figure 4, but the upper top mark's clamping bracket is the 4th one.
It is almost the same as the metal fitting shown in the figure, but the receiving metal fitting 12' on the larger diameter side of the cone is fixed to the short pipe part that holds the core rod (fixed to the core rod with a split pin), the receiving plate, and the upper surface of the receiving plate. It is composed of a rotation stopper 10. In this case, the rotation stopper is of course not fixed to the core rod, and can be attached to and removed from the core rod together with the presser plate 12.

Figure 6 shows one top mark attached to the long core rod 8.
The figure shows the case where a light buoy guard etc. is installed on the pillar.
In this case, the top mark is held between a receiving metal fitting 12' and a holding plate similar to that shown in FIG. The lower part of the column is a support pipe 13' fixed to a guard etc. with U bolts.
It is inserted into the holder and fixed with a cotter pin, etc.

Figure 7 shows a top mark mounting frame in which a top mark mounting plate 16 is mounted and supported by a frame frame 15 on a base plate 14 that is attached to the top of the turret of a light buoy. The frame is placed diagonally so as not to block the light from the Fresnel lens.

FIG. 8 shows another embodiment of a top mark mounting frame, in which the frame frame 15 is in the form of a flat bar, and the direction of the plate is aligned with the direction of the light beam so as not to block the light as much as possible. In either case, the frame mounting flange 9 of the top mark core rod is superimposed on the top mark mounting plate 16 of the frame and fixed with bolts and nuts.

FIG. 9 is a front view showing the case where the mount shown in FIG. 7 is attached to the top of the turret of the light buoy.

Next, we will explain how to attach the top mark.
In FIG. 9, the top mark mounting frame is fixed to the top of the turret of the light buoy with bolts and nuts. Next, the core rod 8
pierce the lower top mark first, and then attach the receiving plate 9'.
, and insert the rotation stopper 10 into the rotation stopper insertion hole 6. Next, the presser plate 12 is passed through the core rod, placed on the top surface of the lower top mark, and fixed by inserting a split pin into the pin hole 13 of the core rod. Next, insert the receiving metal fitting 12' with a rotation stopper into the core rod as shown in the figure and fix it to the core rod with a split pin. Next, insert the upper top mark into the core rod 8, insert the rotation stopper insertion hole 6 of the top mark into the rotation stopper 10 of the receiving metal fitting 12', press the upper top mark with the presser plate 12, and insert a split pin to fix it. Connect the pedestal mounting flange 9 of the core rod with the top mark attached in this way to the top mark mounting plate 1 of the pedestal.
6. Place it so that it aligns with the top and secure it with bolts and nuts.

In this way, any shape of the top mark can be easily attached or removed.
In addition, since the rotation stopper plate 10 is fitted into the rotation prevention insertion hole of the top mark, the top mark will not rotate or wobble even when the buoy oscillates, and the friction between the foamed polyethylene top mark and the core rod will be reduced. There is no chance of the hole in the top mark collapsing, and it will last a long time. Next, the top mark is a hollow body with a hollow thin outer shell made of foamed polyethylene, so it is extremely light and elastic, and the core rod and
Since the receiving fittings and the like are made of light metal or synthetic resin, the overall weight is light and the effect on the stability of the buoy can be minimized, which is a great effect. In addition, parts can be standardized and shared, making it extremely economical. In addition, the top mark is made of foamed polyethylene, which makes it easy to color with paint, has high elasticity, has no risk of breakage, and is highly durable.
