点もある。(Problem to be Solved by the Invention) When the fender 31 is attached to the quay 35 with the center line E perpendicular, when the ship 40 berths and the
Even if the convex portion 41 of the ship 40 shown in the figure comes into contact with the impact receiving portion 32, the reaction force of the fender 31 is not sufficient because the impact receiving portion 32 is uniformly supported by the horizontal ribs 32. Impact energy of the ship 40 can be absorbed. However, if the fender 31 is installed on the quay 35 with the center line E horizontal, the convex portion 41 of the ship 40 will be parallel to the fender 31 as shown in FIG. middle 37 of the ribs 37
When it comes into contact with a, the reaction force of the fender 31 is small, and the fender 31 becomes excessively compressed, causing a problem that the fender 31 is damaged. Furthermore, since the fender 31 cannot absorb the impact energy of the ship 40, there is also the problem that the hull of the ship 40 is damaged.

を提供することを目的とする。 Therefore, the present invention provides that the ship always comes into contact with the ribs of the fender when berthing, regardless of the installation direction of the fender and the contact position of the ship, so that the fender has sufficient elasticity and reaction force. Another object of the present invention is to provide an excellent fender material that can sufficiently absorb impact energy when a ship approaches the berth, allows the ship to berth safely without being damaged, and does not damage the fender material.

ならず、破損も起こらない。 When a ship berths, a convex portion of the ship comes into contact with a receiving portion of a fender fixed to a quay. A connecting rib is provided between a pair of support parts that support the impact receiving part of the fender, intersecting the center line between the pair of support parts, and a connection rib is provided between both ends of the center line of the adjacent connection rib. Since they overlap in the direction perpendicular to the center line between the support parts and are made of rubber-like elastic material, the convex parts of the ship can connect the fenders regardless of the direction in which the fenders are installed. Abuts on any position on the rib. Therefore, the reaction force of the fender is large, and the fender can sufficiently absorb the impact load energy when the ship approaches the berth, and the ship will not be damaged. Moreover, the amount of compression of the fender does not become excessive, and damage does not occur.

It has a pair of support portions 3 having an L-shaped cross section and extending substantially parallel to each other. The support portion 3 is provided with a mounting portion 3a to be attached to the quay wall, and the mounting portion 3a is provided with a plurality of bolt holes 4. Fender 1
is attached to a stud (not shown) in the quay 7 using a bolt hole 4.

とができる。 The fender 1 is attached to a quay with the center line F horizontal, and when a ship berths to the quay 7, a brace is formed between the pair of braces 3 of the fender 1. A plurality of connecting ribs 8 having center lines P and Q whose projections in the center line F direction between the portions 3 overlap by a length E are provided. Therefore, the ship contacts the connecting rib 8 no matter where on the fender 1 it contacts. Therefore, the fender 1 generates an effective reaction force due to the elasticity of the rubber-like elastic material. As a result, the ship will not be damaged, the fender 1 will not be compressed excessively, and it is possible to provide a highly durable fender that will not be damaged. On the other hand, when the fender 1 is installed on the quay 7 with the center line F perpendicular, all the connecting ribs 8 are vertically overlapped between the pair of supports 3 of the fender 1. , No matter where the ship abuts the impact receiving part 2 at the time of berthing, the ship abuts the connecting rib 8. Therefore, also in this case, the same effects as in the case described above in which the fender 1 is attached to the quay wall 7 with the center line F horizontal can be obtained.
