DETAILED DESCRIPTION OF THE INVENTION

(7) The present invention will now be described more fully in detail with reference to the accompanying drawings, in which the preferred embodiments of the invention are shown. This invention should not, however, be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be complete and will fully convey the scope of the invention to those skilled in the art.

(8) FIGS. 1-5 illustrate a watercraft docking device 100 according to the invention. The docking device 100 has a main body 10 that is comprised of one or more conduits 12, which are made of a buoyant material and configured to have two sides 14 that are substantially parallel to one another and connected by end segments 16. The docking device 100 also includes a guide body 30 that is formed from one or more conduits 32, the guide body 30 being attached to or incorporating an end segment 16 of the main body 10. An end segment 16 that is opposite the guide body 30 is configured to attach to a shorefront or to an existing docking or step structure.

(9) In use, the docking device 100 is placed in a body of water with the guide body 30 extending out into the waterbody and with the opposite end segment 16 attached a land area or to another docking structure. The buoyancy of the conduits 12 causes the docking device 100 to float at, on, or near the surface of the body of water. A watercraft, such as a pontoon boat, may be driven into the guide body 30 where guide features help to direct the watercraft over the sides 14 of the device 100, such that there is one pontoon located on either side 14 of the docking device. The guide body 30 also serves as a source of friction, the guide body 30 including buoyant segments that are in the form of friction tubes, and where the friction that is cause by the watercraft passing over the friction tubes helps to slow the speed of entry into and/or onto the docking device 100 while also securing the watercraft in position on the docking device 100 once it is fully docked.

(10) In the embodiment shown in the figures, the main body 10 is comprised of nine separate conduits 12 that are connected by couplings 15. In this embodiment, there is one conduit 12A that is one of the end segments 16 and that is attachable to land or an existing dock. Each side 14 includes two conduits 12B, 12C that run substantially parallel to one another and where each section 12B has substantially the same length and each section 12C has substantially the same length. Each side 14 also includes a pair of conduits 12D that have a downward angle, for example, they may be angled downward between 20 and 60 degrees relative to the other side conduits 12B, 12C. A side support brace 18 or side member 18 connects and stabilizes conduits 12B and 12C. The downward conduits 12D are connected by an end conduit 16.

(11) In the embodiment shown, the guide body 30 incorporates the end conduit 16, and is itself comprised of conduits 12. Additionally, the guide body 30 includes two conduits 32 that extend directly out at substantially 90-degree angles from the end conduit 16, and that connect to a pair of conduits 34 that are angled upward. The upward angle may vary, and anything from 15 degrees to 75 degrees is suitable with an angle around 30 degrees being preferred. Again, the function of the angled guide conduits 34 is to help direct the pontoons over the main body and the angles are set accordingly.

(12) With this specific embodiment, the watercraft first comes into contact with the friction tube 12E, which is perpendicular to the long guide tubes 12B, 12C, 12D. The friction tube 12E naturally floats until the watercraft makes contact, after which the friction tube 12E is pushed under water by the pontoons which slows the watercraft. As the watercraft moves into the dock the watercraft passes over the long guide tubes 12B, 12C, 12D. In the case of a pontoon boat, the long guide tubes 12B, 12C, 12D prevent the pontoons moving side to side by being above the water line and just below the deck of the boat.

(13) Additionally, suitable types of strapping or cordage may be secured to the device 100 and used to further secure a watercraft to the dock 100, primarily for use during times of inclement weather. For example, ropes, straps, or wires may be attached to the ends of conduits 12F and then looped over a pontoon on a pontoon boat to tie the boat in position on the docking device 100.

(14) In multiple-conduit embodiments the various conduits 12 may be attached in a variety of manners. For example, they may be attached to the coupling 15 by adhesives, such as glues that are particularly well suited for water-environments. The conduits 12 may also be attached by threaded fasteners, for example, the end of the conduits 12 and couplings 15 may be configured to have threaded connectors.

(15) FIG. 5 illustrates an embodiment of the docking device 100 that is particularly advantageous for tritoon style hulls, with the side brace 18 having a generally u-shape, and configured with multiple conduits to extend under and around the middle hull in the three-hull design.

(16) The docking device 100 may be comprised of a number of suitable materials. For example, conduits made of polyvinyl chloride (PVC) are particularly well suited for this application. The device may also be made of, for example, high-density polyethylene (HDPE), polypropylene, wood, or it could be made of inflatable materials. In many embodiments all of the components are buoyant, however, only the friction tubes 12E need to be buoyant in order for the device 100 to function as intended.

(17) FIG. 3 illustrates the specific dimensions of one embodiment that is made of PVC products. This model is only one example and many other embodiments are possible.

(18) It is understood that the embodiments described herein are merely illustrative of the present invention. Variations in the construction of the watercraft docking device may be contemplated by one skilled in the art without limiting the intended scope of the invention herein disclosed.
