Abstract

PROBLEM TO BE SOLVED: To provide a fender capable of preventing a shear force from acting on a fixing bolt by providing a cushion part so as to stride over the prescribed angle bent position of a mounting part. SOLUTION: A fender 1 is formed out of a mounting part 2 and a cushion part 3, using an elastic material such as rubber and then mounted on the vertical corner 9 of a quay 8. In this case, the fender 1 is secured with fixing bolt 6 inserted in the bolt hole 5 of the mounting part 2. Furthermore, the mounting part 2 of the fender 1 is bent at right angles, and mounted on the horizontal corner of the quay 8, except for the vertical corner 9. Thus, a force in an arrow direction, even if acting on the fender 1, comes out as a compressive force on the quay 8, but not as a large force on the fixing bolt 6. According to this construction, the fender 1 with the cushion part 3 projected so as to stride over the bent position of the mounting part 2, is bolted to the vertical corner of the quay 8, a shear force does not act on the bolt 6, thereby protecting the bolt 6 against a breakage.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fender.

[0002]

2. Description of the Related Art Generally, a V-shaped fender 13 as shown in FIG. 11 is used as a fender installed on a quay to absorb berthing energy at the time of berthing of a ship. This is formed by projecting a V-shaped buffer portion 15 from the mounting portion 14, and a reinforcing iron plate 17 supporting a fixing bolt 16 inside the mounting portion 14.
Is buried. Such a V-shaped fender 13 is fixed to a quay 18 with a fixing bolt 16 penetrating a reinforcing iron plate 17, and the fixing bolt 16 supports the entire V-shaped fender 13.

[0003]

However, a shear force is applied to the fixing bolt through the reinforcing iron plate by the force shown in FIG. The part was sometimes cut off. For this reason, the fixing of the V-shaped fender becomes loose, and if used as it is, all the fixing bolts may be cut, and the V-shaped fender may come off the quay.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a fender in which no shearing force acts on a fixing bolt.

[0005]

A fender according to the present invention for solving the above-mentioned problems has a shock-absorbing portion provided so as to straddle a bent portion of a mounting portion bent at a predetermined angle. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the fender according to the present invention will be described below in detail with reference to the drawings. 1 is a plan view of the fender of the present invention, FIG. 2 is a front view thereof, FIG. 3 is a side view thereof, and FIG.
FIG. 4 is a sectional view taken along line AA of FIG. 3.

The fender 1 is made of an elastic body such as rubber and comprises a mounting portion 2 and a buffer portion 3. The mounting portion 2 is bent at a predetermined length and at a right angle, and is reinforced by a reinforcing iron plate 4 embedded therein. The mounting portion 2 is bent at a right angle in order to mount the fender 1 to a corner of the quay, and a bolt insertion hole 5 for inserting a fixing bolt 6 for fixing to the quay is provided at an end thereof at an appropriate interval. It is provided for each. Note that the bending angle of the mounting portion 2 is not limited to a right angle, and may be any angle. In addition, mounting part 2
, A semicircular hollow buffer portion 3 is provided so as to straddle the bent portion 7. That is, the buffer portion 3 is formed so as to be symmetrical about the bent portion 7. As the elastic material, besides rubber, elastic materials such as urethane rubber (polyurethane), polyethylene and polyvinyl chloride, and composites thereof may be used. In addition, the buffer part 3 is not limited to hollow, but may be solid.

Further, the fender 1 may be constructed by embedding a laminated material 19 woven into a mesh with fibers or the like in the buffer portion 3. As the laminated material 19, a material knitted with a steel cord or the like other than the fiber may be used. The number of the laminated materials 19 may be one, or two or more may be laminated (FIG. 9).

FIGS. 5 and 6 show a state in which the fender 1 of the present invention is mounted on a vertical corner 9 of a quay 8 and a fixing bolt inserted into the bolt insertion hole 5 of the mounting portion 2. 6
It is fixed at. Since the mounting portion 2 is bent at a right angle, the fender 1 of the present invention is mounted on the horizontal corner other than the vertical corner 9 of the quay 8 as described above. Therefore, in FIG. 5, even if a force in the direction of the arrow acts on the fender 1, the force acts as a compressive force on the quay 8, but does not act as a large force on the fixing bolt 6. , It will never be disconnected.

FIG. 7 shows a quay 11 in which a wave-dissipating block 10 having a sharp tip is assembled and formed with a fender 1 of the present invention, as shown in FIG. (2) is attached to the upper and lower wave-eliminating blocks. Also in this case, fixing is performed by the same method as described above, and the same effect as described above is achieved.

FIG. 10 shows a fender 1 in which the buffer portion 3 is not limited to an arc shape but has a V-shape. As shown in FIG.
9 can also be buried.

[0012]

According to the present invention, even if the fender having the buffer portion protruding from the bent portion of the mounting portion is bolted to the vertical corner of the quay, no shearing force acts on the bolt. It is never cut.

Since the fender can be attached to a corner such as a quay, damage to a ship or the like at the corner can be prevented.
