Document Type and Number:
WIPO Patent Application WO/2018/189941
Kind Code:
A1
Abstract:
A fender device is provided in which shock-absorbing performance is improved. The fender device is attached to a boarding surface at which a ship berths, and comprises a tubular shock-absorbing member. The shock-absorbing member comprises an elastic material, has a center axis extending in the normal direction of the boarding surface, is compressed in the direction of the center axis, and buckles during the process of compression. The shock-absorbing member: has an inner surface; and includes a first convex part that is formed along the peripheral direction on the inner surface when not compressed, and a second convex part that is formed along the peripheral direction on the inner surface near the first convex part when not compressed. The inner surface includes a first peripheral line and a second peripheral line. The first peripheral line demarcates a boundary on the opposite side from the second convex part, which is the boundary of the first convex part. The second peripheral line demarcates a boundary on the second convex part side, which is the boundary of the first convex part. The shock-absorbing member bends along the first peripheral line and the second peripheral line during buckling.
