Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a ladder for a quay that is provided with a reflector to make it easier to see at night.

(Prior Art) Ladders are installed here and there on the quays of ports and harbors, etc., so that people getting on and off the boats from the quays can go up and down the quays, and for people who have fallen into the water to climb up. In addition, water level gauges similar to aquarium water markers are drawn directly on the quay and are affixed to the quay to indicate the water level on the quay due to tides and other factors.

(Problem that the invention attempts to solve) However, although these ladders and water level gauges can be seen and used during the day,
At night, there are few lighting facilities near the quay, making it difficult to see. As a result, it was difficult to locate the ladder on the quay, and it took time for the boat to dock. Additionally, people who fall into the water are at increased risk. Also, it is difficult to read the water level at night, which poses a problem for boats berthing. Therefore, the present invention was made to make it easier to find the location of the quay ladder even at night, and to make it easier to read the water level.

(Means for Solving the Problems) The present invention, as a means for solving the above-mentioned problems, provides for a quay wall ladder to be attached to a vertical wall surface of a quay wall along the vertical direction at least in front of the column part of the ladder. A reflector made of plastic or the like with a plurality of diamond cuts is attached to the reflector.

(Function) With the above configuration, the location of the ladder can be confirmed from a distance by the reflected light from the reflector even on a dark quay at night. Also,
Reflectors installed in rows above and below the ladder generally cannot see anything below the water surface, only what is above the water surface, so the water level can be determined by using the height and position of each reflector as an indicator. be able to.

(Example) Examples of the present invention will be described below with reference to the drawings. In FIG. 1, diamond-cut plastic reflectors 3 are arranged at regular intervals on a ladder 2 provided on a quay 1. As shown in Figure 1, this is the front face 4a of the support columns 4 on both sides of the rubber ladder 2, which also serves as a fender.
It is easy to see from a distance by providing one row at a time. Further, it may be provided on the side surface of the support column 4. In addition,
The number of reflectors 3 arranged can be reduced by placing a larger reflector 3a every fifth than a normal reflector, or by arranging a plurality of normal reflectors horizontally as shown in Figures 2 and 3. It is also useful when counting. In addition, a diamond-cut plastic reflector 3 is attached to the rubber ladder.
To install the ladders in a row, as shown in Figure 4, drill a slightly smaller conical hole 5 in the rubber body of the ladder 2, and insert a diamond-cut plastic body with a conical back surface and a thread into it. Screw in and plant. However, the reflector 3 can be arranged in various ways depending on the situation.

This allows you to see from a distance if Ladder 2 is present even on a dimly lit quay at night, and when you are berthing in a small boat, you only need to aim for Ladder 2 when you berth.
Even those who fall into the water can approach the ladder in the shortest possible distance. In addition, the reflector 3 provided
Since they are not clearly visible under the water, we can only see what is above the water's surface. By counting this,
You can check the water depth even at night. It is especially easy to count because there is a reflector that serves as a landmark every 5th one.
You can check it quickly.

The present invention also includes the following configurations. That is, (a) a reflector may be fitted into the hollow portion 6 as shown by the imaginary line in FIG.

(b) As shown in FIG. 5, triangular or quadrangular reflectors 8 and 9 of different colors may be successively arranged on the support pillars on both sides of the ladder.

(Effects of the invention) Since the present invention has the above-described structure and function, it becomes easy to confirm the installation location of the ladder on the quay even in the dark night by using the diamond-cut reflector. This serves as a guide when small boats on the water approach the quay ladder. Also,
Even if you cannot see the water depth gauge at night, you can use the reflector as a water level scale to determine the water depth.
