The present invention is described more fully hereinafter with reference to the accompanying drawings, in which one or more exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be operative, enabling, and complete. Like numbers refer to like elements throughout. As used herein, the article “a” is intended to include one or more items. Where only one item is intended, the term “one” or similar language is used. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation. Unless otherwise expressly defined herein, such terms are intended to be given their broad ordinary and customary meaning not inconsistent with that applicable in the relevant industry and without restriction to any specific embodiment hereinafter described. Any references to advantages, benefits, unexpected results, or operability of the present invention are not intended as an affirmation that the invention has been previously reduced to practice or that any testing has been performed.
Referring now specifically to the drawings, a mooring device according to one exemplary embodiment of the present invention is illustrated in FIG. 1 and shown generally at reference numeral 10. The mooring device 10 is especially applicable for holding fast a boat “B” on a body of water. In the embodiment shown, the mooring device 10 includes a base 11 secured to the boat “B”, an elongated rigid mooring pole 12 attached at its proximal end 12A to the base 11, and a looped flexible tie line 14 located at a free end 12B of the mooring pole 12. The tie line 14 releasably attaches the mooring pole 12 to an anchoring structure, such as dock cleat 15.
As best shown in FIGS. 1, 2, and 3, the base 11 of the mooring device 12 incorporates overlying rigid plates 18, 19 joined together using threaded bolts 21, 22 and complementary self-locking nuts 23, 24 and washers 25, 26. The bolts 21, 22 pass through respective holes 27, 28 formed with the top plate 18, and through respective adjustment slots 31, 32 formed with the bottom plate 19. The slots 31, 32 allow a predetermined range of adjustment of the top plate 18 relative to the bottom plate 19 and boat “B”. The top plate 18 may have a radiused outside edge 33 which projects beyond an edge of the boat “B”, and a notched inside edge 34 designed to accommodate a boat cleat 35. The inside edge 36 of the bottom plate 19 defines a corresponding cleat notch. The opposite outside edge 37 of the bottom plate 19 extends to the edge of the boat “B”, and may be integrally formed with a side plate 38 designed to reside closely adjacent to a side of the boat “B”. A rubber liner 39 or other intervening structure may reside adjacent the bottom and side plates 19, 38 to protect the surface of the boat “B”. The top plate 18 is fixedly positioned relative to the bottom plate 19 by hand-tightening the bolts 21, 22 using respective knobs 41, 42. The base 11 is then temporarily secured to the boat “B” using a hook 44 and ratchet strap 45. The hook 44 is located at a free end of the ratchet strap 45, and is releasably attached around a neck of the boat cleat 35. The ratchet strap 45 may be mounted to the top plate 18 using suitable hardware 47, 48, and 49, and operates in a conventional manner to force the base 11 tight against the boat “B”.
In one exemplary embodiment, the mooring pole 12 is secured to the base 11 using a multi-pivoted connector 50. As best shown in FIGS. 2 and 3, the connector 50 is attached to the top plate 18 of the base 11 using a threaded bolt 51 and complementary nuts 52, 53. The bolt 51 defines a first pivot point allowing the mooring pole 12 to extend outwardly from the base 11 at one of several pre-selected angles determined by holes 55 formed near the radiused edge 33. When the desired angle is selected, a locking pin 56 is passed through one of two holes 58, 59 formed with the connector 50, and through an aligned one of the holes 55 formed with the top plate 18. The locking pin 56 sets the angle of the mooring pole 12 relative to the base 11, and may be held secure using cotter pin 61. As demonstrated in FIG. 4, the range of angular adjustment may be 120 degrees or more.
An opposite end of the connector 50 is attached to the proximal end 12A of the mooring pole 12 using hardware, such as threaded bolts 62, 63, nuts 64, 65, and washers 66, 67. An intermediate hinge 71 located between the mooring pole 12 and the radiused outside edge 33 forms a second pivot point of the connector 50. As demonstrated in FIG. 5, the hinge 71 allows free angular movement of the mooring pole 12 in a direction generally perpendicular to the top plate 18. This range of movement may also be 120 degrees or more. The first and second pivot points enable adjustment of the mooring pole 12 along respective perpendicular axises.
The mooring pole 12 may be formed of any rigid material, such as lightweight aluminum or other metal, plastic or fiberglass. For added adjustability, the mooring pole 12 may be formed in multiple telescoping sections 74, 75. The inner section 74 may include several longitudinally-spaced holes 76 designed to selectively align with a single hole 77 formed with the outer section 75. Once the mooring pole 12 is adjusted to a desired length, a locking pin 78 may be inserted through the aligned holes 76, 77 and held secure using cotter pin 79. A high-strength universally flexible coil spring or other resilient structure may be located at one or both of the proximal and free ends of the mooring pole 12 for shock-absorption. In the embodiment shown, spring 81 is located at the proximal end 12A of the mooring pole 12, while a rubber bumper 82 is located at the free end 12B of the mooring pole 12.
After assembly and attachment, as described above, the mooring device 10 operates to maintain a safe distance between the boat “B” and the anchoring structure 15 (e.g., dock) as the boat shifts and rocks on the water. In other embodiments of the invention (not shown), the mooring device may be permanently attached at its base to the water craft and stowed in an appropriate compartment when not in use. For particularly large craft, the telescoping mooring pole may be extended via hydraulics or other such means. The mooring device may also be permanently attached to the anchoring structure, and designed for releasable attachment to the water craft. To prevent inadvertent submersion of the mooring device, one or more floatation devices may be attached on or near the mooring pole, base, or tie line.
Exemplary embodiments of the present invention are described above. No element, act, or instruction used in this description should be construed as critical or essential to the invention unless explicitly described as such. Various details of the invention may be changed without departing from its scope. Furthermore, the foregoing description of the exemplary embodiments of the invention and best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation—the invention being defined by the claims and their equivalents.
