DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mooring column to be attached to a quay, a pier, a pier, or the like for hanging a mooring rope of a fishing boat or other ship.

[0002]

2. Description of the Related Art There is known a mooring column made of cast iron in which a horizontal substrate and a hollow columnar portion projecting from the upper surface thereof are integrally cast. Further, the columnar portion includes a straight columnar portion standing upright on the substrate and a fan-shaped head that curves forward from the upper end of the columnar portion and spreads right and left. Circular dents are provided in a row, and a disc-shaped reflector is submerged in this dent, and the reflector receives light from ships and vehicles at night and reflects it, making it easy to confirm the position of the mooring post. It is known (see Japanese Utility Model Publication No. Hei 7-15008).

[0003] However, in the above mooring post, the reflecting plate is submerged in a circular recess in order to prevent the reflecting plate from being damaged by mooring ropes or the like. It is necessary to form according to the shape, thickness and number of plates, and if the shape, thickness, number, etc. of the reflector used is changed after casting, it is extremely difficult to change the shape or depth of the circular recess. there were. When the thickness of the reflector is reduced, the dust is accumulated in the circular recess and the reflector is easily buried in the dust, so that the reflector cannot function, and conversely, the thickness of the reflector is larger than the depth of the recess. When the size of the reflector becomes large, the reflector is exposed from the depression, and there is a problem that the reflector is easily damaged by a mooring rope or the like.

[0004]

SUMMARY OF THE INVENTION
It is an object of the present invention to provide a mooring post in which a reflector having an arbitrary thickness can be relatively easily attached to a mooring post having a reflector attached to the head surface. Second, it provides a mooring post that can be mounted relatively easily in any thickness and shape in any reflector.

[0005]

Means for solving the above-mentioned problem (first means) is to integrally cast a horizontal substrate and a hollow columnar portion protruding from the upper surface thereof, In a cast iron mooring column to which a reflector of an arbitrary shape is fixed, a protrusion having a height larger than the thickness of the reflector is formed integrally with the pillar on the surface of the head of the pillar, and the projection surrounding the reflector is continuous. Protruding in a shape or intermittent shape, a reflector including an array layer of a large number of small glass spheres in an area surrounded by the projection was fixed such that the surface of the glass sphere was lower than the top of the projection. It is characterized by the following.

The above-mentioned columnar portion may be either a straight column having only a columnar portion or a curved column having a fan-shaped head which curves forward from the upper end of the columnar portion and spreads right and left.
In addition, the above-mentioned protrusion can be protruded at an arbitrary position such as a top surface, a front surface, left and right side surfaces, and a back surface as long as it is the head of the columnar portion. Further, the shape may be a shape surrounding a reflector having an arbitrary shape such as a square or a circle, and may be a continuous shape having no gap or an intermittent shape having a gap. For example, it may be projected in a frame shape that continuously surrounds the entire periphery of the reflector such as a square or a circle, or may be formed in two straight lines contacting two upper and lower sides or two left and right sides of a rectangular reflector, or a square. May be provided in a hook shape in contact with the four corners of the reflector. Further, for a disk-shaped reflector, it can be formed in an arc shape that contacts a plurality of locations on the circumference.

The above-mentioned reflector may be formed by arranging and fixing a large number of glass spheres on a support made of synthetic resin which can be fitted into the area surrounded by the above-mentioned projections so that a part of the glass spheres is partially exposed. it can. The support may be transparent, opaque, colorless, or colored. When this support is formed of a colorless or colored transparent body, glass spheres may be buried in the support, and a metal deposition film may be attached to the back surface of the support. The diameter of the glass sphere is 1-4mm
The degree is preferred. The fixing of the reflection plate can be performed by press fitting, bonding, bolting, or the like. In this case, the reflector is fixed inside the protrusion surrounding the predetermined area.If the height of the protrusion is set to be higher in advance, if a thin reflector is attached, the protrusion may be necessary. The height of the part can be adjusted appropriately by shaving the top of the part.

The mooring post is fixed by embedding a horizontal board in an underground concrete near an edge of a quay, a pier, a pier or the like, and is used for hanging a mooring rope of the ship, as in the prior art. You. Then, when light strikes the head of the columnar portion at night, the reflecting plate including the glass bulb is reflected brightly, making it easy to confirm the presence of the mooring column. According to the present invention, the reflector is fixed to the area surrounded by the protrusion protruding from the head surface of the columnar portion, and the surface height of the reflector is lower than the height of the protrusion. There is no possibility that the above-mentioned rope is caught on the reflector and the reflector is damaged or obstructed. In addition, the projections are cut according to the thickness of the reflector, and the height of the projections can be easily adjusted so that the surface of the reflector does not retract too much from the projections. Never hide. In particular, when the protrusions are formed intermittently, it is easy to sweep out dust, and the work of shaving the protrusions for height adjustment is further facilitated.

Means for solving the second problem (second means) is that the head portion of the columnar portion is made of a non-ferrous metal such as aluminum or plastic, for example, separately from the columnar portion,
A protrusion having a height greater than the thickness of the reflector is fixed in a continuous or intermittent shape surrounding the reflector, and a reflector including an array layer of a large number of small glass spheres in an area surrounded by the protrusion. The glass sphere is fixed such that the surface of the glass sphere is lower than the top of the projection. That is, the protrusion in the first means is made of plastic, non-ferrous metal, or the like separate from the columnar part, and is fixed to the head surface by any means. In this case, the protrusion may be provided integrally with the substrate made of plastic or non-ferrous metal separate from the columnar portion, and the reflector may be fixed on the substrate. Also in this second means, the shape of the projection may be any shape as long as it surrounds the reflector of any shape, and may be either a continuous shape with no gap or an intermittent shape with a gap.

According to this second means, since the projection is made completely separate from the columnar portion, when casting the body of the mooring column,
There is no need to consider the shape of the reflector at all, and after casting, the protrusions can be fixed in any shape according to the shape and number of the reflectors, and any number of reflectors can be attached in any shape and mooring. When the rope is attached or detached, the rope does not get caught on the reflector and breaks or hinders the reflector.The surface of the reflector retracts too much from the protrusion, and dust accumulates inside the protrusion. There is no hiding of the reflector. In particular, when the projection is formed integrally with the substrate, the reflection plate can be fixed to the projection in advance via the substrate. In addition,
When a projection is formed integrally with the support on the outer periphery of the synthetic resin support of the reflection plate, and the projection is projected higher than the surface of the glass bulb, the reflection plate is directly fixed to the surface of the head. Since the protrusions can be manufactured by molding, the height of the protrusions with respect to the surface of the glass bulb becomes uniform, and the height adjustment of the protrusions becomes unnecessary.

The surface of the above-mentioned reflector can be covered with a surface material made of a transparent synthetic resin. This surface material may be formed in a desired shape in advance and adhered to the surface of the reflector, but after fixing the reflector to the inside of the protrusion,
It may be fixed to the surface of the support by applying it in the form of a paint to the surface of the reflector and solidifying it. When the surface material is formed in advance, glass spheres may be embedded in the surface material. In addition, as the surface layer material, a material having high hardness after solidification, being hard to be damaged, having a small shrinkage ratio upon solidification, not forming a gap between the concave portions, and having high transparency is preferable. Epoxy resins and the like are exemplified.
Further, the surface shape of the surface material may be any of a flat plate shape, a convex lens shape, a concave lens shape, and the like, but the height of the edge is preferably the same as that of the protrusion, which makes it less likely to be damaged by catching, If dust adheres to the surface, it can be easily washed away by wind and rain, and can be easily wiped off.

[0020]

According to the first aspect of the present invention, the mooring column has a projection formed integrally with the head of the columnar portion so as to surround the reflector, so that the height of the projection is set to be higher in advance. By using a relatively thin reflector, the height of the protrusion with respect to the surface of the reflector can be adjusted by shaving the top of the protrusion, and when using a relatively thick reflector, It can be mounted as it is, and it is easier to adjust the depth of the reflector mounting surface compared to the case where the reflector is mounted in the recess formed on the head surface of the columnar part as before, and the reflector is damaged. It is difficult and the reflector is not buried in dust.

According to the second aspect of the present invention, since the projection is formed separately from the column and fixed to the head of the column, the projection and the recess are formed in the mooring column main body. There is no need to perform the operation, and the reflector can be easily attached to an existing mooring post having no reflector.

According to a third aspect of the present invention, the projection is formed integrally with the substrate on the outer periphery of the substrate separate from the columnar portion, and the reflector is fixed on the substrate. Similarly to the invention described in 2 above, the reflector can be easily attached to the existing mooring post having no reflector, and the reflector can be integrated with the protrusion via the substrate in advance. .
