Description

[Detailed Description of the Invention] The present invention relates to ancillary equipment for a wharf in which a lifting function is added to a fender for mitigating the impact of ships coming alongside.

Conventionally, ladders and the like were attached directly to the quay for easy access. However, since the metal was directly exposed, it was easily corroded, and there was a high risk of damage from collision with the ladder when the ship was coming alongside.

In order to solve the above problems, as shown in Figures 1 and 2, square fenders a are attached to the quay in two rows and connected with rubber-coated chains b to form a ladder. There are things that are.

However, in such a structure, the metal fittings c for fastening the chain b are inserted into the hollow part of the fender a, which deteriorates the cushioning properties of the fender a and also reduces its durability.

Furthermore, since the method of installing two rows of fenders a and connecting them with chain b had the disadvantage that the installation area was inevitably large.

Furthermore, since a core material such as chain b was passed through the rubber part, there was a problem with the durability of the rubber part.

The present invention relates to an improvement of a fender with a ladder that eliminates such drawbacks, and includes a support part that extends from the impact receiving part toward the impact receiving part and the quay wall, and a support part that is integrated with the support part on the quay wall side. In the fender installed on the surface of the quay, the fender comprises a base provided at the quay surface, an impact receiving plate is removably attached to the impact receiving part, and a side wall of the impact receiving plate is provided with a handle oriented laterally. The purpose is to provide an inexpensive fender with a ladder that has excellent cushioning properties and durability.

In this proposal, as described above, the structure is attached to the surface of the quay, which is composed of an impact receiving part, a supporting part extending from the impact receiving part toward the quay, and a base provided integrally with the supporting part on the quay side. In the fender, the impact plate is removably attached to the impact receiving part, and the side wall of the impact plate is provided with a handle that points to the side. It is possible to have the function of

In addition, in this proposal, since a ladder is attached to the fender itself, all that is needed is the installation area of the fender.
Therefore, the installation area may be small.

Furthermore, in the present invention, there is no need to use metal inside the fender in order to provide the function of a ladder, resulting in a fender with excellent durability.

Furthermore, in the present invention, even if the handle and the impact plate are damaged, the impact plate alone can be replaced.

An embodiment of the present invention illustrated in FIGS. 3 and 4 will be described below.

The fender 1 includes a receiving part 2, a supporting part 3 extending from the receiving part 2 toward the quay, and a base 4 provided integrally with the supporting part 3 on the quay side. Become,
An iron plate is embedded in the impact receiving portion 2.

On the other hand, handles 6 are integrally formed on the impact receiving plate 5 at predetermined intervals in the longitudinal direction of the impact receiving plate 5, and the handles 6 function as a ladder for ascending and descending. Note that the handle 6 may be made of metal coated with rubber,
Rubber with high hardness or resin alone may be used.

Then, the impact receiving plate 5 is removably fastened to the front surface of the impact receiving part 2 with bolts 7 using the iron plate inside the impact receiving part.

In FIGS. 3 and 4, the handle 6 attached to the impact-receiving plate 5 has the simplest shape, but by changing the shape of the handle 6, the impact-receiving plate 5 can be
can be given various functions.

Below, in FIGS. 5 to 13, handles 6 with different shapes are illustrated.

FIG. 5 shows an example in which the handles 6 are provided at different levels, making it easier to raise and lower the chair.

FIG. 6 shows the outside of the handle 6 shown in FIG. 5 bent upward, so that even if the foot slides outward, the bent portion still functions as a stopper.

In the case shown in FIGS. 7 and 8, each handle 6 is connected by a left and right handrail 8, and the handrail 8 serves as a non-slip function and can increase the strength of the handle 6. With,
Manufacture of the impact receiving plate 5 is also becoming easier.

Further, in the case shown in FIGS. 9 and 10, the handle 6 is formed in a rectangular shape.
Since the foot can be placed inside, the foot does not slip forward, and in the one shown in FIG. 9, the handle 6 is formed continuously so as not to have an end. It is now possible to increase the strength.

Further, in the case shown in FIGS. 11 and 12, the handle 6 is provided only on one side of the impact plate 5.

Furthermore, as shown in FIG. 13, when the fender 1 is large, the handle 6 can be attached to the recess of the impact plate 5, and in this way, damage to the handle 6 can be prevented. I'm starting to be able to do it.

The impact receiving plates 5 of the embodiments shown in FIGS. 5 to 13 are all fastened to the impact receiving portion 2 with bolts 7. As shown in FIGS.

Since the embodiments shown in FIGS. 3 to 13 are constructed as described above, the handle 6 can be provided without any special measures, which impairs the cushioning properties of the fender 1. It also has excellent durability.

In addition, in this embodiment, the impact plate 5 of the fender 1
Since the handle 6 is provided on the fender 1, the fender 1 can be used as a fender with a ladder function, and the installation area can be reduced.

Furthermore, in this embodiment, even if the impact receiving plate 5 or the handle 6 is damaged, it is only necessary to replace the impact receiving plate 5, which reduces maintenance costs.

Furthermore, since there is a sufficient distance between the support part 3 of the fender 1 and the handle 6, even if the support part 3 is compressed when the ship 9 comes alongside, as shown in FIGS. , there is no risk that the support portion 3 and the handle 6 will come into direct contact and the support portion 3 will be damaged.

In the embodiments shown in FIGS. 3 to 13, the handle 6 is fixed, but as shown in FIG. 16, an insertion hole 10 is formed in the impact plate 5. The handle 11 may be fitted so as to be freely retractable.

In this way, when a ship comes alongside, even if the ship is 9
Even if the handle 11 collides with the handle 11, the handle 11
Since it is recessed inward, no excessive force is applied to the handle 11, and there is no risk of damage to the handle 11 and the handle pivot portion of the impact plate 5.

Further, as shown in FIG.
may be swingably connected by a pin 14.

Even in this case, there is no risk that the impact of coming alongside the ship 9 will be applied to the handle 13 as in FIG. 16.

Further, as shown in FIG. 18, a through hole 15 is formed in the impact receiving plate 5, a handle 16 is slidably inserted into the through hole 15, and rollers 17 are attached to both ends of the handle 16. may be rotatably connected by a pin 18.

Even in this case, the same effects as in FIGS. 16 and 17 can be obtained.

Furthermore, as shown in FIGS. 19 and 20, a spherical pivot 19a is formed on the handle 19,
It may be pivotably supported by the same spherical pivot support 19a.

Note that the impact plate 5 is chamfered 20 so as not to restrict the movement of the handle 19.

In the embodiment shown in FIGS. 19 and 20, the same effects as in FIGS. 16 to 18 can be obtained.
