Abstract

[Problem] To provide a cover member (fender cover) that can cover multiple fenders together, is easy for workers to install, and has sufficient durability to withstand long-term damage. [Solution] The present invention is a cover member used for fenders provided on the outer circumference of a ship's hull. The cover member has a cover portion for covering the fender and an attachment portion provided on the cover portion for attaching the cover portion to the ship's hull. The cover portion is composed of multiple warp threads made of synthetic fibers and multiple weft threads made of synthetic fibers, and has a structure in which two or more warp threads from the multiple warp threads and two or more weft threads from the multiple weft threads are held together and woven.

Description

This invention relates to a cover member for a fender, and more particularly to a cover member for protecting a fender used on a ship. Fenders (also called "fenders") are used to prevent damage to a vessel's hull when it approaches another vessel and makes contact, or when docking. For example, in the case of tugboats, which push and move large vessels within a harbor, multiple fenders are mounted around the hull to prevent damage to other vessels. Generally, rubber materials such as old tires are used as fenders for tugboats. Such fenders have the problem of being damaged during use due to contact and friction between the hull and other vessels or quays. Furthermore, using old tires as fenders can lead to dirt and color transfer to other vessels. To solve these problems, components that cover the fenders are used. Typically, fender covers are made of the same material (cloth) as the sails used on sailing ships. In cases where multiple fenders are pre-attached to the hull, such as on a tugboat, a considerably longer cover is required to cover all the fenders together. This cover is attached to the hull using ropes or similar fasteners at its ends. However, long fabric cover components are susceptible to wind. Therefore, when attaching the cover components to the hull, the wind pressure from sailing and strong winds can cause the components to be buffeted by the wind, making the installation difficult and putting workers at risk. To solve these problems, for example, Patent Document 1 discloses a net made of synthetic fiber or synthetic resin, designed to have a mesh size of 5 to 30 mm, as a cover member. In the cover member of Patent Document 1, the mesh size of the net is sufficiently large, ensuring good ventilation of the cover member. Therefore, it has the advantage of making the installation work easier when attaching the cover member to the hull. However, while fender cover components are required to be durable enough to last for at least two years, the net-formed cover components described above could get caught on protrusions on the hull and break. Under these circumstances, there is a need for a cover component that can cover multiple fenders at once, is easy for workers to install, and possesses sufficient durability.
