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 A mooring post has a straight columnar shape consisting of only a straight columnar portion, and a head which is curved horizontally in succession to the upper end of the columnar portion. A curved column shape is known, and a plurality of circular depressions are provided in a row on the outer peripheral surface of the head portion of the curved mooring column, and a disk-shaped reflector is submerged in the depression. There is also known an apparatus which receives and reflects light from a ship or a vehicle at night to make it easy to confirm the position of a mooring column (see Japanese Utility Model Publication No. Hei 7-15008).

[0003] However, in the above conventional mooring post, since the reflector is submerged in the depression to protect the reflector, the edge of the reflector surface is darkened or blurred, and furthermore, the reflector is not polished. A nut was fixed to the inner surface of the mooring post in advance by welding to facilitate attachment and detachment, and the reflector was bolted using this nut.Then, the nut was welded to the inner surface of the mooring post and tools were prepared for installation. Need to
Further, there is a problem that a part of the surface of the reflector is covered with the head of the fixing bolt.

SUMMARY OF THE INVENTION The present invention does not darken or blur the edges of the reflector, eliminates the need to fix nuts for mounting the reflector, and reduces the surface of the reflector. Is not covered with fixing bolts and the like, and furthermore, a mooring post in which a reflector can be easily attached is provided.

[0005]

A mooring post according to the present invention is a cast iron mooring post having a hollow columnar portion projecting upward at the center of a horizontal substrate. A concave having a shape is provided, and a glass sphere is fixed to the surface of a base made of plastic or rubber having compression elasticity so that a part of the glass sphere protrudes in the concave. The vessel is fixed by press-fitting.

[0006] The mooring column is fixed by embedding a horizontal board in underground concrete near the edge of a quay, a pier, a pier, or the like, and is used for hanging a mooring rope of a ship, as in the past. You. Then, when light hits the head of the columnar portion at night, the reflector is reflected brightly, making it easier to confirm the presence of the mooring post. According to the present invention, since the reflector having a thickness substantially equal to the depth of the recess is fixed to the recess provided in the head by press-fitting, the edge of the reflector becomes dark, or the surface of the reflector is covered with a foreign matter such as a bolt head. Without being
The amount of reflected light increases accordingly. And since the reflector is press-fitted into the recess, there is no need for embedding a nut or an adhesive. In addition, the wall surface inside the depression can be inclined so as to spread on the bottom surface side, and the fixing can be strengthened.
Further, when the reflector is damaged by use, it can be easily removed and replaced with a new one by digging up the base pressed into the depression.

The mooring column may be either a straight column having a columnar portion consisting only of a columnar portion or a curved columnar portion having the upper end of the columnar portion curved horizontally. The fan-shaped head is formed in a hook shape by a fan-shaped head that spreads left and right toward the front, and the outer peripheral surface from the front surface to both side surfaces of the fan-shaped head is substantially the middle portion in the thickness direction of the fan-shaped head. When the concave portion is formed at least on the front surface of the fan-shaped head, the reflected light traveling toward the road ahead is larger because the curvature radius of the front surface is larger than that of the reflector. And the reflector surface is almost perpendicular to the ground, so that the reflected light is reflected almost horizontally without diverting to the sky or the ground, which facilitates confirmation.
If the above-mentioned depression is provided also on the side surface of the fan-shaped head and a reflector is also attached to this side surface, the light reflection direction is widened, and the above-mentioned confirmable range is extended accordingly.

The above-mentioned depression can be provided as a single long groove in a desired range. However, a plurality of grooves may be provided intermittently at intervals, and in the latter case, compared to the former,
A reflector having a short base can be used as the reflector, and firm fixing can be achieved. Also, by providing a plurality of grooves along the maximum bulging apex of the outer peripheral surface of the fan-shaped head, the verticality of the reflector attached to the grooves in the width direction with respect to the ground becomes more accurate.

The above-mentioned depression may be formed in a circular or polygonal shape having a diameter smaller than its depth, and the base of the reflector may be formed in a column shape which can be fitted in the above-mentioned depression. The fixation becomes strong, and a reflector can be attached to any position of the head of the columnar portion, for example, a portion with a large curvature, and a large number of depressions are provided in advance, and the reflector is appropriately attached only to a necessary portion be able to.
