DETAILED DESCRIPTION OF THE PFEFERRED EMBODIMENTS

In describing preferred embodiments of the present invention illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology so selected, and it is to be understood that each specific element includes all technical equivalents which operate in a similar manner to accomplish a similar purpose.

Referring now to Figures 6-11, there is shown a mooring device 10 for boats in accordance with the present invention. Mooring device 10 comprises and arm 12 having first and second ends 12a and 12b and a side surface 12c. As illustrated in Figures 6-11, arm 12 is formed from a tube having a rectangular prismatic form. However, as will be described hereafter, other shapes are possible.

First end 12a is the end of arm 12 designed to be fastened to the boat. Arm 12 has a slot 20 tnerein adjacent first end 12a. Slot 20 extends transversely n a plane perpendicular to the longitudinal axis A of arm 12. Slot 20 is dimensioned to received a cleat Cl of such size and design as is conventionally found on boats. As will be reaαily appreciated, slot 20 is in effect a fixed hook wnich cpens to the side of arm 12.

In order to prevent accidental or unauthorized removal of arm 12 from the boat B, means are provided for locking the cleat Cl m slot 20. As shown in Figures 7, 9, and 11, tne locking means can comprise a bolt 22 slidable in arm 12 along longitudinal axis A into and out of engagement with slot 20. A first eye 24 is affixed to arm 12 and a second eye 26 is affixed to bolt 22 through a longitudinal slot 28 provided in side surface 12c of arm 12. Second eye 26 is positioned to align with first eye 24 when bolt 22 is in engagement with slot 20, in order to receive a padlock.

As will be appreciated by those of skill in the art, arm 12 with slot 20 and bolt 22 can be fabricated by a variety of conventional machining methods. Referring to Figures 9 and 11, one method contemplated by the present invention is to form first end 12a in two pieces using a piece of square tubing 30 for the main body of arm 12 and a oloc 32 as an insert carrying bolt 22. Transverse slot 20 is formed m block 32, and longitudinal slot 28 is formed in two aligned sections 28a and 28b extending inwardly from the open ends of tubing 30 and block 32, respectively. Bolt 22 is inserted into the open end of biocr 32, and then clock 32 is inserted into the open enα of : Ding 30 and welded flush.

Referring now to Figures 6-8 and 10, a rotatable hook 40 dimensioned to engage a cleat C2 on a dock D or a second boat is mounted on second end 12b cf arm 12 for rotation about an axis parallel to longitudinal axis A. Second end 12b is planar, and hook 40 opens towards second end 12b. Hook 40 is rotatable 180° between an open position (in which its open side is rotated to one side cf second end 12b) for engaging or releasing cleat C2 and a closed position (in which its open side lies flush against second end 12b) for retaining cleat C2. In its open and closed positions, hook 40 lies in a plane perpendicular to the plane of slot 20. Considering slot 20 as defining or being equivalent to a fixed hook, then hook 40 is oriented 90° to the fixed hook.

As will be appreciated by those of skill in the art, second end 12b of arm 12 carrying hook 40 also can be fabricated by a variety of conventional machining methods. Referring to Figures 8 and 10, as with first end 12a, second end 12b can be formed in two pieces, square tubing 30 forming the main body of arm 12 and a block 42 as an insert carrying hook 40. Hook 40 has a long attached leg 40a, which is inserted into block 42, and a short free leg 40b which engages second end 12b in the closed position. long leg 40a rests n a longitudinal channel 44 formed n one side of block 42. Long leg 40a is formed with two necked-in portions 46, which align with a pair cf slots 53 formed transversely across channel 44. Two U-shaped clips 52 fit over necked-in portions 46 and into slots 50 and are welded to hold long leg 40a m place in block 42. Similar to the assembly of first end 12a, block 42 is inserted into the open end of tubing 30 and welded flush.

In order to moor a boat B to a dock D or another coat 32, two parallel mooring devices 10 preferably are used, as shown m Figures 1 and 4, extending between one side of the boat B and the dock D or one side of the other boat B2. Each mooring device is installed in the same manner. Hook 40 is opened and arm 12 is oriented with slot 20 facing upwardly, as shown m Figure 6. The free leg 40b of hook 40 is inserted through a cleat C2 on the dock D or other boat B2, as also shown in Figure 6, and arm 40 is rotated 180° to close hook 40, as further shown m Figure 7. Slot 20, now facing downwardly, is placed over the cleat Cl on the first boat B, and bolt 22 is slid into engagement with slot 20 to lock arm 12 m place, as also shown in Figure 7. If desired, a padlock can be inserted through first and second eyes 24 and 26. Rope R can additionally be used to tie the boat B to the dock D or other boat B2, for example in a "V" as shown in Figure 1, or in an "X" configuration as shown m Figure 4, to further secure the boat B.

Due to the relative orientation of hook 40 to slot 20, arm 12 is locked m place on the dock D or other boat B2 once arm 12 is turned to receive the cleat C2 in slot 20. Further, once bolt 22 is secured by a padlock, arm 12 cannot be turned to release hook 40 from the cleat C2 on the dock D or other boat B2. Thus, mooring device 10 is locked at both ends, although the user only manipulates first end 12a.

As shown m Figure 2, a single mooring device 10 can also be used to moor a boat B to a dock D or another ooat . Ropes R in an "X" configuration are used to tie the side of the boat 3 to the dock D or other boat, and mooring device 10 is attached as described above between the center of one side of the boat B and the dock D or other boat, so as to extend over or under the ropes R where they cross . Also, a single mooring device 10 can be attached as described above between the stern of a forward boat F and the bow of a rearward boat R, for towing, as shown in Figure 5.

Several alternative embodiments are possible to enable the boat to be maneuvered between its docked position and a boarding position. In one alternative embodiment, shown in Figures 3 and 12, arm 12' includes first and second parallel hinges 60a and 60b inset from the first and second ends 12a and 12b, respectively. First and second hinges 60a and 60b pivot on vertically-oriented axes perpendicular to longitudinal axis A and are pivotable m opposite directions, enabling the portion of arm 12' between first and second hinges 60a and 60b to be oriented substantially parallel to the boat side for boarding and deboarding, and substantially perpendicular to the boat side for docking. In another alternative embodiment, shown in Figure 13, arm 12" is telescopic. Arm 12" can thus be extended and retracted to adjust for lower and higher tides.

In a third alternative embodiment, shown in Figures 3 and 14, mooring device 10 additionally includes rotating cleats 70 installed on the boat and the dock or other boat to wnich it is to be moored. Rotating cleats 70 comprise the shackle portion 72 of a conventional cleat rotatably connected to a threaded shaft 74 for attachment to a boat deck or dock D. Metal plates 76 are attached above and below deck or dock D at the side of cleat 70, and threaded shaft 74 is inserted through aligned holes in metal plates 76 and deck or dock D, and secured in place by a conventional washer 80 and nut 82. Rotating cleats 70 enable arms 12 to be oriented perpendicular to the boat side for docking and to be oriented at a severely acute angle to the boat side for boarding and deboarding.

Modifications and variations of the above-described emccdiments of the present invention are possible, as appreciated by those skilled m the art in light of the above teachings. For example, arm 12 need not be rectangular prismatic in form, but can have a circular cress-section.

It is therefore to be understood that, within the scope of the appended claims and their equivalents, the invention may be practiced otherwise than as specifically described.
