BACKGROUND OF THE INVENTION The fender in use is fitted to the wharf side or ships side, but more often to the wharf side. The conventional fender is usually formed like a pillar and this pillar-fender contains a longitudinal cavity, which does not open on the Contact suface which engages the ship. With good absorption of impact energy, the fender of this type has been increasingly preferred in use, but it has the drawback that its contact surface on the ships side is limited. This drawback is compensated by applying various separate members to this contact surface.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fender to be used for protecting a ships hull.
The primary object of this present invention is to provide a fender with an enlarged ship contact surface area assuring excellent absorption of impact energy. The conventional fender heretofore used in itself has a narrow ship contact area and it occasionallygives a dent to the ships hull. In the present invention, the ship contact area is enlarged to eliminate this drawback of the conventional fender heretofore known.
A second object of this present invention is to provide a fender which is applicable regardless of the ships size.
A third object of this present invention is to provide a fender, simple in structure and easy in manufacturing, that can give the abovementioned effects.
The objects and effects of this present invention will be better understood from the following description of an embodiment.
FIG. 1 shows a fender of this present invention as viewed from the contact surface which engages the ship,
FIG. 2 shows a section along the line lI--II of FIG. 1,
FIG. 3 is a contact surface view of amodied form of the fender,
FIG. 4 is a cross-sectional view taken on line 4-4 of FIG. 3, and
FIG. 5 is a contact view of a further modified form of the fender.
On a circular resilient rubber plate 2 having a base mounting lfixture 1 are bored a plurality of hexagonal pillar holes 3,3' starting from a ship contact surface 7 ice and running to said base fixture 1 and at appropriate intervals. In said base fixture 1 an iron plate 4 is embedded parallel to the wharf fitting contact surface against the wharf and at the same time an insertion hole 6 for a bolt 5 is provided in the base, said bolt 5 being driven into the wharf side is put into said insertion hole 6; and then a nut is screwed onto said ybolt for fastening. The ship contact surface 7 is realtively large.
The FIGS. 1 and 2 illustrates only as an example, hexagonal holes 3,3 being bored in the circular rubber plate, but the holes can be circular as shown in FIGS. 3 and 4, triangular square as shown in FIGS. 3 and 4 or polygonal other than hexagonal. The large number of holes 3a running toward the wharf contact fitting surf-ace may be through holes as shown in FIGS. 3 and 4.
The assembly is a rubber plate 2 bored with many vertical or vertical holes 3,3 and 3b through holes 3a to the wharf side, appropriately spaced from each other.
A fender of the above construction is mounted vertically to the wharf side by means of the insertion holes 6 of the fender 2.
When a ships hull comes into contact with the external contact surface 7 of this fender, this fender comes into contact With the hull over a very sapcious area instead of the narrow area in the case of a conventional fender as heretofore known, so that the hull is not damaged; thereby the holes 3,3 and 3b or the through holes 3a running from the external ship contact surface 7 to the fitting surface 1 against the wharf can absorb the strain of the rubber plate 2 due to the contact evenly over the entire surface of said plate. And this effect will be exhibited reagrdless of the ships size. Said iron plate serves to preserve the configuration of the fender and strengthen the fixture.
I claim:
1. In a wharf fender for ships, a substantially flat base fixture, a relatively thick resilient rubber plate having a. large ship engaging surface, a fitting surface engaging said base, said rubber plate being provided with a plurality of parallel bores extending through its thickness from its ship engaging surface and being open at said ship engaging surface, a reinforcement plate embedded in said base fixture and extending parallel to the wharf engaging surafce of said base fixture and retaining means adapted to be fastened to said base fixture and said rubber plate for holding the same against a wharf side.
2. A fender according to claim 1, said bores extending through said base and said plate from the ship engaging surface to the wharf engaging surface.
3. A fender according to claim 1, said bores being hexagonal.
4. A fender according to claim 1, said bores being polygonal other than hexagonal.
5. A fender according to claim 1, said bores being circular.
