This invention pertains to connectors adapted to connect to the end of a rope or cable, and more particularly, to such connectors mounted to the bottom surface of a floating object that selectively connect to a rope or cable attached to an anchor that holds the floating object in a restricted area over the anchor.
It is common to tie a floating dock or raft to a rope or cable attached to an anchor. During use, waves, wind and tides cause the floating dock or raft to drift back and forth in a restricted area on the water above the anchor.
It is also common to attach the end of the rope or cable to a single cleat or to a ring attached to the side or top surface of the dock or raft. Because cleats and rings are fixed structures, forces exerted on them by the rope or cable cause the dock or raft to rotate in the water so that the side of the dock or raft with the cleat or ring faces the anchor. Also, because the cleat or ring are attached to the side or top surface of the dock or raft, repetitive lateral and vertical forces are exerted on the cleat or ring causing the cleat or ring to loosen and eventually disconnect from the dock or raft.
Ideally, what as is needed is an improved attachment system for restricting movement of a floating dock or raft over a submerged anchor that does not cause the dock or raft to rotate to a particular orientation and is better suited to withstand the repetitive forces exerted on a floating dock or raft.
An improved floating object attachment system for attaching one end of a rope or cable attached at one end to a submerged anchor. The system includes use of a rotating swivel arm mounted on a support pole that extends downward from the bottom surface of the floating object, such as a floating dock or raft. The support pole is attached to a rigid mounting plate that attaches to the bottom surface of the floating object. The swivel arm includes a horizontal flange that attaches at one end to the support pole and extends laterally. Integrally formed or attached to the distal end of the horizontal flange is an outward extending diagonal flange with a grommet attached at its distal end that connects to an anchor rope or cable. Because the swivel arm rotates freely around the support pole and the diagonal flange is angled downward, tension on the anchor rope or cable does not cause the floating object to rotate in the water and the anchor rope and cable stays clear of the support pole.
The support pole includes a plurality of radially aligned gussets that securely hold the support arm in a fixed perpendicularly aligned position on the mounting plate. The support pole includes a lower stop surface and an upper stop surface that holds the swivel arm on the support pole. Nylon washers are placed around the support arm and between the swivel arm and the upper and lower stop surfaces.
Referring to the
The mounting plate 26 is a rigid plate structure made of metal configured to attached to a flat bottom surface 82 of a floating object 80. The mounting plate 26 includes a plurality of holes 28 that received suitable connectors 30 used to securely attach the mounting plate 26 to the bottom surface 82 of the floating object 80.
The support pole 24 is a solid or hollow pipe affixed to the mounting plate 26 and aligned with the plate's center axis 27. A plurality of radially aligned gussets 32 are attached to the mounting plate 26 and to the support pole 24. The gussets 32 hold the support arm 24 perpendicularly aligned with the mounting plate 26.
The swivel arm 40 includes a horizontal flange 42 with a center bore 44 adapted to receive the support pole 22. The horizontal flange 42 is perpendicularly aligned with the support pole's longitudinal axis. The swivel arm 40 also includes a diagonal flange 46 that extends downward. Formed near the distal end of the diagonal flange 46 is a main hole 50. Inserted into the main hole 50 formed on the diagonal arm 46 is a grommet 48 with curved or beveled edges that reduce abrasions to the rope or cable 90.
The support pole 24 includes a lower stop surface 26 and an upper stop surface 60. The lower stop surface 26 and upper stop surface 60 are spaced apart to form a rotation section 41 for the swivel arm 40 to rotate on the support pole 22. When assembled, the horizontal flange 42 is positioned between the lower and upper stop surfaces 26, 60 so that support pole 40 extends through the center bore 44 and the diagonal flange 46 points downward. Disposed around the support pole 40 and between the horizontal flange 42 and the lower and upper stop surfaces 26, 60 are at least one nylon washer. In the embodiment shown herein, there are two pairs of nylon washers, 32, 32′, and 53, 53′ respectively.
Inserted into the main hole 50 formed on the diagonal arm 46 is a grommet 48 with curved or beveled edges that reduce abrasions to the rope or cable 90.
In the embodiment shown herein, the support pole 24 is approximately 2 inches in diameter and 9 inches in length. The swivel arm 40 is a plate structure approximately 3 inches in width and 6 inches in length. The horizontal flange 42 is approximately 3 inches in length. The diagonal flange 46 is disposed at a 45 degrees angle from the horizontal flange 42. The center bore 44 formed in the horizontal flange 46 is approximate 2⅛ inches in diameter. The main hole 50 on the is approximately 2¼ inches in diameter. The stop surfaces 26, 60 are circular plates approximately 3 inches in diameter. In the embodiment shown, the stop surfaces 26, 60 are made of metal and welded to the support pole 22. In should be understood the stop surfaces could be pegs or bolts that extend laterally from the support pole 22 and permanently or selectively affixed to the support pole 22. The nylon washers 32, 32′, 54, and 54′ are approximately 3 inches in diameter and ¼ inch thick. The support pole 22, the swivel arm 40, the stop surfaces 26, 60 are made of stainless steel or galvanized steel.
In compliance with the statute, the invention described has been described in language more or less specific as to structural features. It should be understood however, that the invention is not limited to the specific features shown, since the means and construction shown, comprises the preferred embodiments for putting the invention into effect. The invention is therefore claimed in its forms or modifications within the legitimate and valid scope of the amended claims, appropriately interpreted under the doctrine of equivalents.
