Abstract

An apparatus for inhibiting damage from impact between a marine structure and an adjacent watercraft, and a related method, are described. The apparatus includes a cushion body forming a mounting surface and a watercraft-engaging surface substantially opposing the mounting surface, at least one rigid support member, the rigid support member defined by or configured for contact with the mounting surface of the cushion body and disposed, during use, between the cushion body and the portion of the marine structure, and attachment means for detachably attaching the cushion body to the portion of the marine structure. The cushion body, when attached to the portion of the marine structure, is sized and configured to prevent destructive contact between the marine structure and a watercraft when the watercraft-engaging surface is contacted by the watercraft.

Claims

1. An apparatus for detachable attachment to a portion of a marine structure, the apparatus comprising

a cushion body forming a mounting surface and a watercraft-engaging surface substantially opposing the mounting surface;

at least one rigid support member, the rigid support member defined by or configured for contact with the mounting surface of the cushion body and disposed, during use, between the cushion body and the portion of the marine structure; and

attachment means for detachably attaching the cushion body to the portion of the marine structure,

wherein the cushion body, when attached to the portion of the marine structure, is sized and configured to prevent destructive contact between the marine structure and a watercraft when the watercraft-engaging surface is contacted by the watercraft; and

wherein the attachment means comprises at least one releasable strap assembly, the releasable strap assembly comprising

a first strap comprising a first structure end portion and a first tension device end portion, wherein the first structure end portion is sized and configured to attach to the portion of the marine structure;

a second strap comprising a second structure end portion and a second tension device end portion, wherein a portion of the second strap is disposed within at least one of the plurality of channels and the second structure end portion is sized and configured to attach to the portion of the marine structure; and

a tension device coupled to the first tension device end portion and the second tension device end portion, the tension device being sized and configured to increase the tension in the first strap and/or second strap by adjusting the length of the first strap and/or the second strap when the first structure end portion and the second structure end portion are attached to the portion of the marine structure thereby securing the cushion body to the portion of the marine structure.

2. The apparatus of claim 1 wherein the first structure end portion and the second structure end portion each comprise a universal mount and a bracket, wherein the bracket is sized and configured to be coupled to the universal mount and to retain the cushion body to the portion of the marine structure.

3. An apparatus for detachable attachment to a portion of a marine structure, the apparatus comprising

a cushion body forming a mounting surface and a watercraft-engaging surface substantially opposing the mounting surface;

at least one rigid support member, the rigid support member defined by or configured for contact with the mounting surface of the cushion body and disposed, during use, between the cushion body and the portion of the marine structure; and

attachment means for detachably attaching the cushion body to the portion of the marine structure,

wherein the cushion body, when attached to the portion of the marine structure, is sized and configured to prevent destructive contact between the marine structure and a watercraft when the watercraft-engaging surface is contacted by the watercraft; and

wherein the rigid support member defines at least two elongate dovetailed grooves on one or more faces of the rigid support member, the dovetailed grooves extending the longitudinal length of the rigid support member at opposing longitudinal side portions of the rigid support member, each of the grooves being sized and configured (i) to receive respective elongated, channel-forming flaps extending from the cushion body, and (ii) retain a respective one of the flaps when a respective elongated retention member is threaded through the respective one of the flaps when it is disposed in its respective groove.

4. The apparatus of claim 3 wherein the rigid support member comprises a bent or bendable panel of rigid support material.

5. The apparatus of claim 4, wherein the rigid support material comprises high density, marine grade polymer.

6. The apparatus of claim 4, wherein the panel is bent or bendable into a right angle.

7. The apparatus of claim 3, wherein the rigid support member comprises a support frame assembly comprising two support frames sized and configured to be detachably attachable to one another.

8. The apparatus of claim 7, wherein each support frame comprises an elongate frame member and two or more cross members, each cross member being configured at one end for attachment to the elongate frame member and configured at its other end for detachable attachment to the other support frame at a corresponding cross member of the other corresponding support frame.

9. The apparatus of claim 8, wherein the elongate frame member is triangular in cross-sectional shape, with a bottom face and a groove-forming top face, each running the length of the elongate frame member, wherein each groove-forming top face defines one of the dovetailed grooves.

10. A method for preventing damage to a watercraft or a marine structure, the method comprising

disposing a cushion body forming a mounting surface and a watercraft-engaging surface substantially opposing the mounting surface proximate a receiving surface of the marine structure;

disposing at least one rigid support member between the cushion body and the marine structure;

detachably attaching the rigid member to the cushion body and to the marine structure;

wherein the cushion body comprises a solid or semi-solid resilient material, wherein the step of detachably attaching the rigid member to the cushion body and to the marine structure comprises (a) attaching a releasable strap assembly to the marine structure and to either the cushion body or the rigid member or to both the cushion body and the rigid member, or (b) attaching the cushion body to the rigid member, or (a) and (b), and wherein the cushion body is attached to the rigid member by a process comprising inserting elongated, channel-forming flaps connected to and extending from the cushion body into respective dovetailed grooves formed in one or more faces of the rigid member and threading respective elongated retention members through channels formed by the channel-forming flaps, respectively, while the flaps resides in their respective grooves, so as to secure the flaps to the rigid member.

11. A method for preventing damage to a watercraft or a marine structure, the method comprising

disposing a cushion body forming a mounting surface and a watercraft-engaging surface substantially opposing the mounting surface proximate a receiving surface of the marine structure;

disposing at least one rigid support member between the cushion body and the marine structure;

detachably attaching the rigid member to the cushion body and to the marine structure;

wherein the cushion body comprises a solid or semi-solid resilient material, wherein the step of detachably attaching the rigid member to the cushion body and to the marine structure comprises (a) attaching a releasable strap assembly to the marine structure and to either the cushion body or the rigid member or to both the cushion body and the rigid member, and (b) attaching the cushion body to the rigid member; and

wherein the cushion body is attached to the rigid member by a process comprising inserting elongated, channel-forming flaps connected to and extending from the cushion body into respective dovetailed grooves formed in one or more faces of the rigid member and threading respective elongated retention members through channels formed by the channel-forming flaps, respectively, while the flaps resides in their respective grooves, so as to secure the flaps to the rigid member.
