Boat Docking and Cleaning Device

Abstract

A docking and cleaning device comprising a frame having scrubbers affixed thereto for cleaning a boat hull at a horizontal section, such as the waterline. The frame comprises a movable elongated member so that when the frame is in an “open” position, the elongated members provide an opening through which a boat may pass, entering into a docking area formed by the frame. The elongated member is moved so that the frame is in a “closed” position where the frame substantially conforms to the shape of the boat hull. Wave motion acting on the boat and the frame allow the scrubbers to frictionally contact and clean the boat hull at the waterline.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a boat docking and cleaning device. The device holds the boat in position a desired distance away from a dock while cleaning a horizontal cross-section, such as at the waterline section, of the boat hull.

2. Description of Related Art

An ongoing problem for experienced and novice boaters alike is the docking of their boats without contacting nearby stationary structures, such as a dock. Such contact may often cause scuffs or damage to the boat hull. When docking, most boaters require assistance from a dockside assistant or passenger to handle ropes or to push off the dock. This assistance is especially needed on the approach to a dock where currents and wave action may affect a projected course. Commonly, where waves and currents are an issue, docks are equipped with fenders to absorb any contact by an approaching boat. Alternatively, once the boat is docked, various fenders may be placed either along the dock or on the side of the boat hull to prevent physical damage that may result from the boat hull contacting with the dock due to wave action. Various fender devices are discussed, for example, in U.S. Pat. Nos. 5,018,471 to Stevens and 5,732,645 to Lemke. A drawback of these fenders is that the impact they are designed to absorb is not distributed over a large area. Thus, the fenders may damage the boat hull or the dock in the position where they are located.

Boat owners are also routinely confronted with maintenance tasks associated with keeping a boat docked in the water for periods of time. The attachment of organic material and the formation of slime on the boat hull at the waterline is unsightly and may damage the boat hull over time. Thus, cleaning the boat hull is a task that is generally performed at intervals by the boat owner using mechanical brush devices while standing on the deck of the boat or from dockside. U.S. Pat. No. 4,648,344 to Burgers et al. discloses the use of a brush to clean the boat hull while standing on a dock. Alternatively, the boat may be removed from the water and dry-docked to access the boat hull for cleaning.

Other conventional boat hull cleaning devices provide scrubbing action laterally across the bottom of the boat hull, port to starboard (left to right). These devices are inconvenient to use because they usually require moving the cleaning device along the boat hull to clean the entire hull. Alternatively, if the cleaning device is mounted in a fixed position, the boat itself must be moved past the cleaning device to clean the entire hull. In this regard, U.S. Pat. No. 4,843,995 to Bingham discloses a boat hull cleaning device mounted in a fixed position adjacent to a water passageway. A line stretched across the passageway cleans the boat hull by passing the boat over the line, which forces a scrubber section of the line against the boat hull. Maloney et al., U.S. Pat. No. 5,222,452 (“the Maloney '452 patent) discloses a boat hull cleaning apparatus mounted to a dock. The apparatus comprises a row of motorized rotary brushes extending into the body of water. A boat is moved past the row of brushes to clean the boat hull.

Other hull cleaning devices provide scrubbing action longitudinally along the bottom of the boat hull from bow (front) to stern (back), instead of laterally across the bottom of the boat hull from port to starboard. For example, Rogers, U.S. Pat. No. 4,401,048 discloses a device that scrubs a longitudinal section of a boat hull. The boat remains stationary in the water, and the device moves along the boat hull from bow to stern to clean the underwater portion of the boat hull. The device cleans a section of the boat hull in the particular location where the device is positioned. The device must be repositioned to clean the remaining sections of the boat hull.

Despite the various conventional docking and hull cleaning systems known in the art, there remains a need for a docking system that maintains a boat in position away from the dock and cleans the boat hull at the waterline without taking the boat out of the water.

BRIEF SUMMARY OF THE INVENTION

The present invention is directed to a docking device for guiding a boat into a docking area and holding the boat in position while cleaning the boat hull periphery at a horizontal cross-section of the boat, preferably at the waterline. The present invention is also directed to a method for the simultaneous docking and cleaning of a boat using such a device.

In one aspect, the boat docking and cleaning device of the present invention comprises a frame shaped to conform to a shape of a substantial portion of a horizontal cross-section of a boat hull. The frame is such that is it conforms to at least 50%, 60%, 70%, 80%, 90%, or 100% of the horizontal cross-section of the boat hull, preferably at the water line. In the latter case (100%), the frame completely surrounds the boat hull a horizontal cross section (e.g., at the water line). In other aspects, the frame surrounds about 50 to 100%, about 50 to 90%, about 50 to 80%, about 50 to 70%, about 60 to 100%, about 60 to 90%, about 60 to 80%, about 70 to 100%, about 70 to 90%, about 70 to 80% of the boat hull.

In one aspect, the frame preferably comprises a first elongated member, a second elongated member, and an optional base section. The first elongated member and the second elongated member each have a first end and a second end. The first end of the first elongated member and the first end of the second elongated member are movably, preferably pivotably, connected to each other. Alternatively, at least one of the first elongated member or second elongated member is movably, preferably pivotably, connected to the optional base section. The second end of the first elongated member and the second end of the second elongated member are movably connected to each other such at least one of the second ends are adapted to move toward and away from each other in an “open” and “closed” position. A scrubber is affixed to the frame for cleaning the boat hull. Preferably, the scrubber frictionally engages and cleans at least 50% of the boat hull at the waterline. Thus, in one aspect, the scrubber frictionally engages and cleans at least 50%, 60%, 70%, 80%, 90%, or 100% (or some range therebetween) of the horizontal cross-section of the boat hull, preferably at the water line. In other aspects, the scrubber frictionally engages and cleans about 50 to 100%, about 50 to 90%, about 50 to 80%, about 50 to 70%, about 60 to 100%, about 60 to 90%, about 60 to 80%, about 70 to 100%, about 70 to 90%, about 70 to 80% of the boat hull.

In another aspect, the first elongated member and/or the second elongated member of the frame comprise a plurality of frame sections. Further, in another aspect, the scrubber comprises a plurality of scrubber segments mounted on the frame or frame sections. The scrubber segments may form a continuous scrubber such that there are no gaps between adjacent scrubber segments, or may be non-continuous. The scrubber segments are preferably adjustable so that the angle of the scrubber relative to the waterline (i.e., relative to horizontal) may be adjusted depending on the shape of the boat hull or the depth at which the device floats in the water. The angle is typically about 30, 40, 45, 50, 55, 60, 65, 70, 75, 85 degrees relative to horizontal or some range therebetween.

In still another aspect, the frame comprises a first and second elongated member movably connected, preferably pivotably, to a base section. The base section may be adapted to conform to the shape of the bow of the boat or the shape of the stern of the boat.

In yet another aspect, the docking and cleaning device is comprised of materials so that the device floats at or just below the waterline of a body of water. Typically, the device floats no more than 0, 1, 2, 3, 4, or 5 feet below the waterline (or some range therebetween).

The present invention is also directed to a boat docking and cleaning system comprising the boat docking and cleaning device as described herein, and further comprising least one mooring line. The mooring lines are used to tether the device to the dock and/or pilings.

In another aspect, the present invention is directed to a docking and hull cleaning device comprising a frame having a first elongated member and a second elongated member. At least one of the elongated members is movable (preferably pivotable) between a closed position and an open position. In the closed position, the frame defines an interior boat docking area. The frame is complementary in shape to a boat hull at a horizontal cross-section thereof when the elongated members are moved to the “closed” position. The frame is adapted to form an opening for docking or undocking the boat when the elongated members are moved to the “open” position. A scrubber is affixed along at least a portion of the interior of one frame. Preferably, the scrubber frictionally engages and cleans at least 50% of a boat hull at the waterline.

In another aspect, the present invention is directed to a method for docking a boat and cleaning the hull of a boat. The device as described herein is floated on a body of water. The frame of the device, which is shaped to conform to the shape of a horizontal cross-section of the boat hull (preferably at the waterline or just below the waterline), defines an interior docking area for the boat and has a scrubber mounted thereon. The boat is placed in the interior boat docking area to dock the boat and permit the scrubber to frictionally engage the boat hull to clean the boat. Typically, the frame of the device is moored to the dock and/or piling(s) using at least one mooring line.

In one aspect, the method for docking and cleaning the boat includes providing a device in which the frame comprises a first elongated member and second elongated member pivotably connected to an optional base section or to each other. In such a case, the boat is placed in the interior docking area by pivoting the first and/or second elongated members to form an opening in the frame. The boat is likewise removed from the docking and cleaning device by pivoting the first and/or second elongated members to form an opening in the frame.

Additional aspects of the invention, together with the advantages and novel features appurtenant thereto, will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following, or may be learned from the practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

The present invention is directed to a boat docking and cleaning device for guiding a boat into a docking area and holding the boat in position while cleaning a substantial portion of a horizontal cross-section of the boat hull periphery, preferably at the waterline. The present invention is also directed to a method for docking a boat and cleaning a boat hull using the devices disclosed herein.

The docking and cleaning device generally comprises a frame and one or more scrubbers attached to the frame. In a preferred embodiment, the frame comprises a first elongated member, a second elongated member, and an optional base section. One or more of the first and second elongated members are movable in an “open” position and a “closed” position. In the “open” position, the frame and scrubbers provide a resilient bumper to aid a boater in maneuvering the boat into the docking area. Once in the docking area, the elongated members of the frame are moved to a “closed” position, wherein the frame preferably completely surrounds the boat hull at the waterline including the bow, sides, and stern portions of the boat hull. In this position, the device is adapted to allow the boat to move up and down with the motion of the water and yet avoid undesirable contact with the dock associated with dock mooring. Further, the scrubbers positioned on the frame function as both a resilient cushion against the boat hull while docking and as a scrubber while the boat is docked to clean the boat hull at the waterline region. The scrubbers frictionally contact the boat hull at the waterline and clean the boat hull as the frame and hull move in response to the motion of the surrounding water.

As used herein, the term “boat” includes any type of watercraft designed to float or plane on water, including but not limited to motorboats, sail boats, and jet skis.

As used herein, the terms “float,” “floating,” and “floatable” mean the positional status of being or the ability to be afloat either at, on, or below the surface of a body of water (typically not more than 5 feet below the surface of the body of water) and not sink to the bottom of the body of water.

While several exemplary embodiments of the present invention are discussed below, those skilled in the art will readily appreciate that various modifications may be made to these embodiments, and the invention is not limited to the configurations described therein. For example, the frame of the boat docking and cleaning device may be constructed of a number of different members and materials, provided that the frame surrounds a majority of the boat hull at a horizontal cross section. In that regard, many of the exemplary embodiments discussed below are preferred embodiments in which the frame (and scrubbers) are designed to contact boat hull at the entire horizontal cross-section. That is, the frame extends around the entire (100%) periphery of the boat hull at a horizontal cross section (e.g., at the waterline). However, it is within the scope of the present invention that the frame (and/or scrubbers) could extend around 50%, 60%, 70%, 80%, or 90% of the boat hull, and still be able to clean a substantial portion of the boat hull while docking the boat as generally shown in the seventh embodiment. In such a case, it is anticipated that the frame ends (e.g., the ends of the two elongated members) could be connected together using a rope, chain, or other connection device. In such a case, the boat would still be docked within an interior docking area defined by the docking device (the frame connected together by the rope).

First Exemplary Embodiment

Referring to FIGS. 1, 2, and 3, a combination docking and cleaning device in accordance with a first exemplary embodiment of the present invention is designated generally by the number 10. The device 10 comprises a frame 12 having a base section 14 attached to two elongated members 20A, 20B. The frame 12 is shaped so that the bow of a boat 28 is docked first. Once the boat is docked, the shape of frame 12 generally conforms to the shape of the boat hull at the waterline cross-section.

FIG. 1 illustrates the docking and cleaning device 10 in an “open” position with a boat 28 positioned therein. FIG. 2 illustrates the docking and cleaning device in a “closed” position with the same boat 28 positioned therein. As shown in both FIGS. 1 and 2, the base section 14 is generally shaped to correspond to the bow of the boat 28. Thus, the base section 14 is generally V-shaped and comprises first and second members 14A, 14B which converge and join at apex 16 at one end and extend and bow outwardly from apex 16 to ends 18A, 18B.

The docking frame 12 further includes two elongated members 20A, 20B having first ends 22A, 22B and second ends 24A, 24B. The elongated members 20A, 20B are generally adapted to engage the boat stern. The first ends 22A, 22B are pivotably attached to ends 18A, 18B of the base section 14 respectively at movable joints 26A, 26B. The second ends 24A, 24B are adapted to move or swing toward and away from each other about movable joints 26A, 26B. This permits docking of the boat 28 as generally illustrated in FIG. 1. As shown in FIG. 2, the second ends 24A, 24B are removably connected to each other to form the enclosed docking area. Typical connection devices used to removably connect second ends 24A, 24B of the elongated members include, but are not limited to latches, clasps, hooks and eyes, buckles, ties, rope, locks, and the like.

In this embodiment, the elongated members 20A, 20B generally curve toward each other so that their shapes correspond to the shape of the stern of the boat 28 when the frame is in a “closed” position. As shown in FIGS. 1 and 2, elongated members 20A, 20B are generally L-shaped.

FIG. 3 illustrates the cross-section of the device 10 floating on the water surface. The cross-section can be taken along any part of the frame of the device. The frame 12 has a cross-section which is generally rectangular in shape, but it will be appreciated to those skilled in the art that other shapes, such as circular, elliptical, and the like are within the scope of the present invention. The frame 12 is preferably made of a material which is buoyant, rot-proof, rust-proof, and water resistant. Exemplary materials include wood, plastic, fiberglass, or metal. Alternatively, if the density of a selected material for the frame 12 does not allow it to float on the surface of the water, the frame 12 may optionally be configured with flotation devices such as buoys (not shown) attached to the frame 12 to allow the frame 12 to float at the water's surface.

As shown in FIG. 3, a scrubber 50 comprising a plurality of brushes 52 is connected to the interior of the frame 12. The scrubber 50 preferably extends along the entire interior periphery of the frame 12 such that the brushes 52 frictionally engage the entire horizontal cross-section of the boat hull (i.e., the bow, stern, and sides) at the waterline as generally shown in FIG. 2 when the boat is in a “closed” position. Preferably, the scrubber 50 extends along at least 50%, 60%, 70%, 80%, 90%, or most preferably at least 95% of the periphery of the frame 12 such that the brushes 52 engage a corresponding portion of the horizontal cross-section of the boat hull at the waterline. The brushes can have a variety of thicknesses and may have brush densities optimized for cleaning the device but that are easily cleaned by washing.

As shown in FIG. 3, the scrubber is adapted to generally contact the boat hull at the waterline. The brushes 52 are preferably comprised of anti-abrasive bristles made of synthetic material, such as nylon, suitable for the marine environment. Optionally, the scrubber 50 may comprise carpet pads or elastomeric pads, and may be mechanically actuated and controlled as generally shown in the Maloney '452 patent, which is incorporated by reference. Preferably, the scrubbers are resilient and provide impact absorption.

In FIG. 3, the scrubber 50 is attached to the frame 12 using one or more support brackets. The angled C-shaped bracket 49 is affixed to the top and bottom of frame 12 using one or more fasteners 48 (e.g. nails, screws, bolts, adhesive, Velcro and the like). One or more elongated brackets 44 are attached to the scrubber 50 at one end and are attached to the C-shaped bracket 49 using fasteners 48 at the other end. The bracket 44 preferably includes an elongated aperture or slot 46 to adjustably engage the fasteners 48 such that the position and/or angle of the scrubber 50 is adjustable. Alternatively, the frame 12 may be shaped so that it is tightly held within bracket 49 without the need for fasteners.

Further, it will be appreciated that various other fastening means for attaching the scrubber 50 to the frame 12 and attaching elongated bracket 44 to C-shaped bracket 49 are well known, such as hook and loop fasteners, clips, u-bolts, and rivets, are within the scope of the present invention.

The scrubber 50 is preferably angled so that the brushes 52 frictionally engage the boat hull at the waterline, where the majority of the slime and other aquatic material is most likely to accumulate on the boat hull. In FIG. 3, the angle of the scrubber is such that the brushes 52 engage the boat hull at the radius of curvature defined by the boat hull at the waterline. The angle θ of the scrubber is preferably 30 to 85 degrees relative to horizontal, and is typically about 60 to 80 degrees relative to horizontal (i.e., relative to the waterline).

Looking at FIGS. 1 and 2, the frame 12 is held in position in relation to the dock 54 by a mooring system 56. The mooring system 56 comprises one or more pilings 58 and one or more mooring lines 60. The mooring system 56 further includes various cleats, shackles, pulleys, and other tying-off devices as is known to those skilled in the art (not shown). Exemplary mooring lines 60 include ropes, cable, chains, and the like.

FIGS. 1 and 2 show the top ends of the pilings 58 which are part of mooring system 56. Typically, the bottom end of pilings 58 are secured to the bottom of the sea or water bed or the submerged part of an adjacent marine structure. The first end of each mooring line 60 is attached generally to the top end of pilings 58 and the second end of each mooring line 60 is attached to the frame 12 at attachment point 62. The attachment point 62 is typically a cleat or ring (not shown). Optionally, the first ends of the mooring lines 60 may be attached to the dock 54 instead of the pilings 58.

With the structure of the boat docking and cleaning device set forth above, the operation of the device will now be described. Looking to FIG. 1, the mooring lines 60 of mooring system 56 are adapted to allow the frame 12 to be positioned in a desired location relative to the dock 54. Typically, tension in the mooring lines 60 is set to keep the frame 12 from unwanted contact with the dock 54 while still allowing for the limited movement of the device 10 caused by the tide and the wave action of the water.

As shown in FIG. 1, for a docking operation, the frame 12 is first placed in an “open” position by the user. In the “open” position, the base section 14 and the elongated members 20A, 20B form a generally V-shape docking area 30. The second ends 24A, 24B of the elongated members 20A, 20B form an opening or entrance to the interior docking area 30 through which a boat 28 may pass. As the bow of a boat 28 approaches and contacts device 10, the scrubbers 50 mounted to the elongated members 20A, 20B resiliently urge and guide the boat 28 into the docking area 30. As the boat 28 advances, the scrubbers 50 continue to urge and align the boat 28 into the docking area 30 until the bow contacts apex 16. Once the bow of the boat 28 contacts apex 16, the elongated members 20A, 20B are moved or swung toward each other until the second ends 24A, 24B of the elongated members 20A, 20B are connected together. When the elongated members 20A, 20B, are connected together (e.g., using latches 32A, 32B), the device is in the “closed” position as generally shown in FIG. 2.

In the “closed” position, the frame 12 forms the enclosed docking area 30, holding the boat 28 in a desired position. The boat hull is continuously in contact with scrubber 50 on the frame 12 of the device 10. The motion of the water, including waves and tidal action, provides movement of the docking and cleaning device 10 and the boat 28 in relation to each other. This movement translates into frictional action of the scrubber 50 against the boat hull. The frictional action of scrubber 50 against the boat hull provides a scrubbing action to continuously clean the periphery of the boat hull at the waterline—including the sides, bow, and stern—all while the boat is in the water.

When undocking the boat 28 from docking area 30, the elongated members 20A, 20B are moved or swung apart, forming an opening between the second ends 24A, 24B of the elongated members 20A, 20B. The boat 28 then exits from docking area 30 by moving astern between the opening formed by the second ends 24A, 24B. The scrubbers 50 on the elongated members 20A, 20B help urge and guide the boat 28 out of the docking area 30 until the boat 28 is clear of the device 10.

In one aspect, the elongated members 20A, 20B are manually moved or positioned in the “open” and “closed” position. It will be appreciated to one skilled in the art that latches 32A, 32B and/or elongated members 20A, 20B can be equipped with motors or other actuating devices known to those skilled in the art so that the device is mechanically driven. Further, the motors may be adapted with receivers to respond to remote control command signals to move the elongated members 20A, 20B.

Second Exemplary Embodiment

Referring to FIGS. 4-5, a combination docking and cleaning device in accordance with a second exemplary embodiment of the present invention is designated generally by the number 110. The device 110 of the second exemplary embodiment is different from the device 10 of the first exemplary embodiment in three principal ways. First, the device 10 of the first exemplary embodiment is designed as “bow-first” when docking, while the device 110 of the second exemplary embodiment is designed as “stern-first” when docking. Second, the frame 112 of the device in the second embodiment is equipped with ballast tank to alter the depth of the frame device 110. Third, the device 110 of the second exemplary embodiment is comprised of a plurality of scrubber segments instead of a continuous single scrubber along the frame.

As shown in FIGS. 4-5, the device 110 of the second exemplary embodiment comprises a frame 112 having a base section 114 attached to two elongated members 120A, 120B. The frame 112 is shaped so that the stern of the boat 128 is docked first. Once the boat 128 is docked, the shape of the frame 112 generally conforms to the shape of the boat hull at the waterline cross-section.

FIG. 4 illustrates the docking and cleaning device 110 in an “open” position with a boat 128 positioned therein. FIG. 5 illustrates the docking and cleaning device in a “closed” position with the same boat 128 positioned therein. As shown in both FIGS. 4 and 5, the base section 114 is generally shaped to correspond to the stern of the boat 128. Thus, the base section 114 is generally C-shaped and comprises ends 118A, 118B.

As will be apparent, the overall shape of the frame 112 in the second exemplary embodiment is substantially identical to the frame 12 described above with respect to the first exemplary embodiment when in the “closed” position. As with the first embodiment, the docking frame 112 of the second embodiment includes two elongated members 120A, 120B having first ends 122A, 122B and second ends 124A, 124B. The elongated members 120A, 120B are generally adapted to engage the boat bow. The first ends 122A, 122B are pivotably attached to ends 118A, 118B of the base section 114 respectively at movable joints 126A, 126B. The second ends 124A, 124B are adapted to move or swing toward and away from each other about movable joints 126A, 126B. This permits docking of the boat 128 as generally illustrated in FIG. 4. As shown in FIG. 5, the second ends 124A, 124B are removably connected to each other to form the enclosed docking area. Typical connection devices used to removably connect the second ends 124A, 124B of the elongated members include, but are not limited to latches, clasps, hooks and eyes, buckles, ties, rope, locks, and the like.

In this embodiment, the elongated members 120A, 120B generally curve toward each other so that their shapes correspond to the shape of the bow of the boat 128 when the frame is in a “closed” position. As shown in FIGS. 4 and 5, elongated members 120A, 120B are generally C-shaped.

As shown in FIG. 5A, to float or position the frame 112 at various depths in the water, the frame 112 is configured with a hollow core 134 similar to a ballast tank that is well known in the art. The hollow core 134 is adapted to be filled with water or emptied through tube opening 136 to adjust the buoyancy of the frame 112. The tube opening 136 is configured with a cap 138 for sealing the contents of the core 134. When the hollow core 134 contains increasing amounts of water or other filler materials that correspondingly increases the overall density of the frame. In such a case, the frame 112 floats at a lower level in the water. Similarly, removing water from the core 134 will raise the level at which the frame 112 floats in the water.

FIG. 5A also shows that the scrubber 150 is adapted to generally contact the boat hull at the waterline or just below the waterline. In a manner similar to FIG. 3, the scrubber 150 is attached to frame 112 using one or more support brackets. Again, in this embodiment, the angled C-shaped bracket 149 is affixed to the top and bottom of frame 112 using one or more fasteners 148. One or more elongated brackets 144 are attached to the scrubber 150 at one end and are attached to the C-shaped bracket 149 using fasteners 148 at the other end. The bracket 144 includes an elongated aperture or slot 146 to adjustably engage the fasteners 148 such that the position and/or angle of the scrubber 150 is adjustable.

In the second exemplary embodiment, the angle of the scrubber is somewhat lower than that of the first exemplary embodiment of the device illustrated in FIG. 3. The angle of the scrubber is preferably 30 to 85 degrees relative to horizontal, and is typically about 60 to 80 degrees relative to horizontal (i.e., relative to the waterline). Further, while the scrubber 50 in the first exemplary embodiment extends along the entire interior periphery of the frame 112 as one continuous scrubber unit, FIG. 5B illustrates a scrubber 150 comprising a plurality of adjacently positioned scrubber segments 150A-150E to form a substantially continuous scrubber along frame 112. Each of the scrubber segments 150A-150E is held in place by the brackets illustrated in FIG. 5A, and thus may be independently adjustable to the desired angle relative to the waterline.

Looking at FIGS. 4-5, frame 112 is typically held in position in relation to dock 154 by mooring system 156. The mooring system 156 is similar to that in the first embodiment. One or more mooring lines 160 connect the boat docking and cleaning device 110 to the dock 154 and/or pilings 158 at various attachment points 162.

The operation of the boat docking and cleaning device is similar to the first exemplary embodiment. Looking to FIG. 4, the mooring lines 160 of mooring system 156 are adapted to allow the frame 112 to be positioned in a desired location relative to the dock 154. Typically, tension in the mooring lines 160 is set to keep the frame 112 from unwanted contact with the dock 154 while still allowing for the limited movement of the frame 112 caused by the tide and the wave action of the water.

As shown in FIG. 4, for a docking operation, the frame 112 is in an “open” position. In the “open” position, the base section 114 and the elongated members 120A, 120B form a generally U-shape docking area 130. The second ends 124A, 124B of the elongated members 120A, 120B provide an opening or entrance to docking area 130 through which a boat 128 may pass. As the stern of a boat 128 approaches and contacts device 110, the scrubbers 150 mounted to the elongated members 120A, 120B resiliently urge and guide the boat 128 into the docking area 130. As the boat 128 advances, the scrubbers 150 continue to urge and align the boat 128 into the docking area 130 until the stern contacts the base section 114. Once the stern of the boat 128 contacts the base section 114, the elongated members 120A, 120B are moved or swung toward each other until the second ends 124A, 124B of the elongated members 120A, 12B are connected together. When the second ends 124A, 124B are connected together (e.g. by a latch 132A, 132B on each end), the device 110 is in the “closed” position as generally shown in FIG. 5.

As shown in FIG. 5, in the “closed” position, the frame 112 forms the enclosed docking area 130, holding the boat 128 in a desired position. The boat hull is continuously in contact with the scrubber 150 on the frame 112 of the device 110. The motion of the water, including waves and tidal action, provides movement of the docking and cleaning device 110 and the boat 128 in relation to each other. This movement translates into frictional action of the scrubber 150 against the boat hull. The frictional action of scrubber 150 against the boat hull provides a scrubbing action to continuously clean the periphery of the boat hull at the waterline—including the sides, bow, and stern—all while the boat 128 is in the water.

When undocking the boat 128 from docking area 130, the latch 132A, 132B is disengaged and the elongated members 120A, 120B are moved or swung apart, forming an opening between the second ends 124A, 124B of the elongated members 120A, 120B. The boat 128 then exits from docking area 130 by moving the bow first between the opening formed by second ends 124A, 124B. The scrubbers 150 on the elongated members 120A, 120B help urge and guide the boat 128 out of the docking area 130 until the boat 128 is clear of the device 110. Motors or other actuating devices known to those skilled in the art so that the device is mechanically driven. Further, the motors may be adapted with receivers to respond to remote control command signals

Third Exemplary Embodiment

Referring to FIGS. 6-7, a combination docking and cleaning device in accordance with a third exemplary embodiment of the present invention is designated generally by the number 210. The device 210 of the third exemplary embodiment differs from the prior two embodiments in that there is no optional stationary base section. Thus, the device 210 comprises a frame 212 having two elongated members 220A, 220B. Further, in this embodiment, the scrubber 250 is attached to the frame 212 using an alternative bracket system. In addition, the device 210 of the third exemplary embodiment is comprised of a plurality of scrubber segments having gaps between adjacent scrubber segments.

As shown in FIGS. 6-7, the boat docking and cleaning device 210 of the third exemplary embodiment comprises a frame 212 shaped so that the bow of the boat 228 is docked first. Once the boat 228 is docked, the shape of frame 212 generally conforms to the shape of the boat hull at the waterline cross-section.

FIG. 6 illustrates the docking and cleaning device 210 in an “open” position with a boat 228 positioned therein. FIG. 7 illustrates the docking and cleaning device in a “closed” position with the same boat 228 positioned therein. The overall shape of frame 212 is substantially identical to the frames 12, 112 described above with respect to the prior exemplary embodiments when the device is in the “closed” position. That is, the entire horizontal cross-section of the boat is surrounded by the frame 212 when in the closed position. Further, scrubbers 250 are positioned along the entire interior periphery of the frame 212 (although, as discussed above, there are gaps between adjacent scrubber segments).

As shown in FIGS. 6-7, the docking frame 212 includes two elongated members 220A, 220B having first ends 222A, 222B and second ends 224A, 224B. The elongated members 220A, 220B are generally adapted to engage the boat stern. In this embodiment, unlike in the first and second embodiments discussed above, the first ends 222A, 222B are pivotably attached together at movable joint 226, and not to a stationary base section. The second ends 224A, 224B are adapted to move or swing toward and away from each other about a movable joint 226. This permits docking of the boat 228 as generally illustrated in FIG. 6. As shown in FIG. 7, the second ends 224A, 224B are removably connected to each other to form the enclosed docking area. Typical connection devices used to removably connect the second ends 224A, 224B of the elongated members 220A, 220B include, but are not limited to latches, clasps, hooks and eyes, buckles, ties, rope, locks, and the like.

In this embodiment, the elongated members 220A, 220B generally curve toward each other so that their shapes correspond to the shape of the stern and bow of the boat 228 when the frame is in a “closed” position. As shown in FIGS. 6-7, elongated members 220A, 220B are generally L-shaped.

FIG. 7A shows the cross-section of the frame 212. In this embodiment, one or more support brackets 244 are used to attach the scrubber 250 to the frame 212. The brackets 244 are fixedly attached to frame 212 at one end and are removably attached to the scrubber 250 at the other end. Thus, the scrubber 250 can be replaced as needed when the brushes 252 become worn. The support brackets 244 include an elongated aperture or slot 246 to adjustably engage fasteners 248 such that the position and/or angle of the scrubber 250 is adjustable. The angle of the scrubber is preferably 30 to 85 degrees relative to horizontal, and is typically about 60 to 80 degrees relative to horizontal (i.e. relative to the waterline). Further, while the scrubber 50 in the first exemplary embodiment extends along the entire interior periphery of the frame 12 as one continuous scrubber unit, FIG. 7B illustrates a scrubber 250 comprising a plurality of adjacently positioned scrubber segments 250F-220I. In contrast to the second embodiment where the scrubber segments 150A-150E form a continuous scrubber system, the scrubber 250 in the third exemplary embodiment has a gap between some or all of the adjacently positioned scrubber segments 250F-250I to from a non-continuous scrubber 250.

Looking at FIGS. 6-7, frame 212 is typically held in position in relation to dock 254 by mooring system 256. The mooring system 256 is similar to the prior embodiments, i.e. one or more mooring lines 260 connect the boat docking and cleaning device 210 to the dock 254 and/or pilings 258 at various attachment points 262.

The operation of the boat docking and cleaning device 210 is similar to the prior embodiments. Looking to FIG. 6, the mooring lines 260 of mooring system 256 are adapted to allow the frame 212 to be positioned in a desired location relative to the dock 254.

As shown in FIG. 6, for a docking operation, the frame 212 is in an “open” position. In the “open” position, the elongated members 220A, 220B form a generally V-shape docking area 230. The second ends 224A, 224B of the elongated members 220A, 220B provide an opening or entrance to docking area 230 through which a boat 228 may pass. As the bow of a boat 228 approaches and contacts device 210, the scrubbers 250 mounted to the elongated members 220A, 220B resiliently urge and guide the boat 228 into the docking area 230. As the boat 228 advances, the scrubbers 250 continue to urge and align the boat 228 into the docking area 230 until the bow is adjacent first ends 222A, 222B. Once the bow of the boat 228 is adjacent first ends 222A, 222B, the elongated members 220A, 220B are moved or swung toward each other until the second ends 224A, 224B are in contact with one another or alternately connected together. The second ends 224A, 224B are moved towards each other, thereby placing the device 210 in the “closed” position. The second ends 224A, 224B are held together by engaging latches 232A, 232B.

As shown in FIG. 7, in the “closed” position, the frame 212 forms the enclosed docking area 230, holding the boat 228 in position. The boat hull is continuously in contact with scrubber segments (e.g. 250F-250) forming the scrubber 250 on frame 212 of device 210. The motion of the water causes frictional action to continuously clean the periphery of the boat hull at the waterline—including the sides, bow, and stern—all while the boat 228 is in the water. The boat 228 may be undocked by reversing the steps above in a manner similar to the prior embodiments.

Fourth Exemplary Embodiment

Referring to FIGS. 8-9, a combination docking and cleaning device in accordance with a fourth exemplary embodiment of the present invention is designated generally by the number 310. The device 310 comprises a frame 312 having two elongated members 320A, 320B. The device 310 is similar to the device 210 of the third exemplary embodiment in that it does not comprise a base section. However, the device 310 of the fourth exemplary embodiment is different from that in the third embodiment insofar as the frame 312 is shaped so that the stern of the boat 328 is docked first. Once the boat 328 is docked, the shape of the frame 312 generally conforms to the shape of the boat hull at the waterline.

FIG. 8 illustrates the docking and cleaning device 310 in an “open” position with a boat 328 positioned therein. FIG. 9 illustrates the docking and cleaning device in a “closed” position with the same boat 328 positioned therein. The overall shape of the frame 312 is the same as in the prior exemplary embodiments when the device is in the “closed” position.

Similar to the third embodiment, the frame 312 of the fourth embodiment includes two elongated members 320A, 320B having first ends 322A, 322B and second ends 324A, 324B. The elongated members 320A, 320B are generally adapted to engage the bow of the boat 328. This embodiment is similar to the third embodiment in that the first ends 322A, 322B are pivotably attached together at movable joint 326, and not to a stationary base section. The second ends 324A, 324B are adapted to move or swing toward and away from each other about a movable joint 326. This permits docking of the boat 328 as generally illustrated in FIG. 9. As shown in FIG. 9, the second ends 324A, 324B of the elongated members 320A, 320B are removably connected to each other to form the enclosed docking area 330.

In this embodiment, the elongated members 320A, 320B generally curve toward each other so that their shapes correspond to the shape of the hull of the boat 328 when the frame is in a “closed” position. As shown in FIGS. 8-9, elongated members 320A, 320B are generally L-shaped.

The cross-section of the device 310 and the scrubber configuration for the fourth embodiment can be any of those described in FIGS. 3, 5A, 5B, 7A, and/or 7B for the prior embodiments, or any combination thereof. For example, the cross-sectional construction or shape of the frame is non-limiting. Further, the frame may be comprised of a buoyant or non-buoyant material. In the latter case, the device may include flotation devices such as buoys (not shown) attached to frame to allow frame to float. The frame may be positioned on or below the surface of the water. In addition, a scrubber or a plurality of scrubbers segments may be provided along the frame. Preferably, the scrubbers, such as brushes, extend along 50% to 100% (e.g., 50%, 60%, 70%, 80%, or 90%) of the periphery of the frame such that the brushes engage a majority of the horizontal cross-section of the boat hull, e.g., the waterline section or just below the waterline. The angle of the scrubbers may also be adjustable in relation to the shape of the boat hull or the position of the device in the water.

Looking at FIGS. 8-9, the frame 312 is typically held in position in relation to dock 354 by mooring system 356. The mooring system 356 is similar to the prior embodiments. In general, one or more mooring lines 360 connect the boat docking and cleaning device 310 to the dock 354 and/or pilings 358 at various attachment points 362.

The operation of the boat docking and cleaning device is similar to the third exemplary embodiment. Looking to FIG. 8, the mooring lines 360 of mooring system 356 are adapted to allow the frame 312 to be positioned in a desired location relative to the dock 354.

As shown in FIG. 8, for a docking operation, the frame 312 is in an “open” position. In the “open” position, the elongated members 320A, 320B form a generally U-shaped docking area 330. The second ends 324A, 324B of the elongated members 320A, 320B provide an opening or entrance to the docking area 330 through which a boat 328 may pass. As the stern of a boat 328 approaches and contacts device 310, the scrubbers 350 mounted to the elongated members 320A, 320B resiliently urge and guide the boat 328 into the docking area 330. As the boat 328 advances, the scrubbers 350 continue to urge and align the boat 328 into the docking area 330 until the stern is adjacent to the first ends 322A, 322B. Once the stern of the boat 328 is adjacent to the first ends 322A, 322B, the elongated members 320A, 320B are moved or swung toward each other until the second ends 324A, 324B are in contact with one another or are otherwise connected together. Preferably, the second ends 324A, 324B are held in contact with one another by the engaging latches 332A, 332B, thereby placing device 310 in the “closed” position. Other suitable connection devices include hook and loop fasteners, ropes, clips, ties, and even velcro.

As shown in FIG. 9, in the “closed” position, the frame 312 forms the enclosed docking area 330, holding the boat 328 in position. The boat hull is continuously in contact with the scrubber 350 on the frame 312 of the device 310. The motion of the water causes frictional scrubber action against the boat hull to continuously clean the periphery of the boat hull at the waterline—including the sides, bow, and stern—all while the boat 328 is in the water. To undock the boat, the elongated members 320A, 320B are moved a part to the “open” position as generally shown in FIG. 8, and reversing the steps generally described above.

Fifth Exemplary Embodiment

Referring to FIGS. 10-11, a combination docking and cleaning device in accordance with a fifth exemplary embodiment of the present invention is designated generally by the number 410. Similar to prior embodiments, the device 410 comprises a frame 412 having elongated members 420A, 420B that conform to the shape of the hull of a boat at a horizontal cross-section, preferably at the waterline cross-section. The device 410 is similar to the prior embodiments, except that the elongated members 420A, 420B are comprised of a plurality of frame sections 412A-412I. Although illustrated as having nine frame sections 412A-412I, it is within the scope of this invention for the quantity of frame sections to vary. e.g. the elongated members 420A, 420B may be comprised of 2, 3, 4, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, etc., frame sections.

FIG. 10 illustrates the docking and cleaning device 410 in an “open” position with a boat 428 positioned therein. FIG. 11 illustrates the docking and cleaning device in a “closed” position with the same boat 428 positioned therein. As will be apparent, the overall shape of frame 412 is similar to frames 12, 112, 212, 312 described above in prior embodiments when in the “closed” position. As shown in FIG. 10, the boat docking and cleaning device 410 of the fourth exemplary embodiment comprises a frame 412 shaped so that the bow of the boat 428 is docked first. Once the boat 428 is docked, the shape of the frame 412 generally conforms to the shape of boat hull at the waterline cross-section.

As shown in FIGS. 10-11, the docking frame 412 includes two elongated members 420A, 420B having first ends 422A, 422B and second ends 424A, 424B. The first elongated member 420A is comprised of fixedly connected and adjustable frame sections 412A-D. The second elongated member 420B is comprised of fixedly connected and adjustable frame sections 412E-I. The elongated member 420A and the elongated member 420B generally curve toward each other so that their shapes correspond to the shape of the hull of the boat 428 when the frame 412 is in a “closed” position.

The frame sections may be fixedly connected using a number of connecting means, e.g. nails, screws, brackets, rivets, bolts, adhesive, Velcro, rope, and the like. Most preferably, however, the frame sections 412A-H may be adjusted to a number of fixed positions. In one aspect, as shown in FIGS. 12 and 13, frame sections 412A-D and 412E-H are fixedly connected together via adjustable connection brackets 470A, 470B. Each frame section 412A-H comprises a first connection bracket 470A affixed to a first end of each frame section and a second connection bracket 470B affixed to the second end of the frame section. The first connection bracket 470A is configured with a positioning through-hole 472A and a guide through-hole 474A. The second connection bracket 470B is configured with one positioning through-hole 472B.

The overall shape (i.e., the desired curve) of elongated members 420A, 420B may be adjusted by altering the position of the frame sections relative to one another. That is, the frame sections 412A-H may be adjusted to a number of fixed positions. More specifically, the shape of the elongated members 420A (comprising the frame sections 412A-D) and 420B (comprising frame sections 412E-H) is adjusted by connecting the first connecting bracket 470A on a frame section with the second connecting bracket 470B of an adjacent frame section at an angle that allows the frame sections to correspond generally to the shape of the boat hull at the waterline or other horizontal cross-section.

By way of example and not limitation, as shown in FIG. 13, frame section 412A and 412B are placed in relation to each other such that connection bracket 470A of the frame section 412A is positioned on top of or below connection bracket 470B of the frame section 412B. Once the positioning holes 472A, 472B are aligned, a fastener (e.g., screw, nail, bolt, etc.—not shown) is loosely inserted through the positioning holes 472A, 472B. The frame sections are then positioned to correspond to the shape of the boat hull at the waterline at a section, such that a desired angle is formed between connection brackets 470A and 470B. The fastener inserted in the positioning holes 472A, 472B is then tightened. Next, a hole (not shown), similar in diameter to the guide hole, is drilled through or otherwise formed in alignment with the guide hole 474A in connection bracket 470A into the connection bracket 470B. Another fastener (not shown) is inserted through the guide hole 474A and the newly drilled hole, and the fastener is tightened to hold the frame sections at a fixed position (i.e., the desired angle). Alternatively, a series of pre-drilled or pre-formed holes may be positioned in connection bracket 470B and the fastener may be placed through any hole that aligns with the guide hole 474A to hold the frame at the desired angle. By adjusting the angle between adjacent frame sections, the overall curve or shape of the frame may be adjusted so that it better corresponds to the shape of the boat hull at a horizontal cross-section, such as the waterline section. This permits the user to customize the shape of the frame to a particular boat, if need be.

In this embodiment, as in the third embodiment discussed above, the first ends 422A, 422B are movably (preferably pivotably) attached together at a movable joint 426. The second ends 424A, 424B are adapted to move or swing toward and away from each other about the movable joint 426. This permits docking of the boat 428 as generally illustrated in FIG. 10. As shown in FIG. 11, the frame section 412I of the elongated member 420B is further adapted to move or swing toward and away from the frame section 412A of the elongated member 420A about the movable joint 480. The frame section 412I is removably connected to frame section 412A to form the enclosed docking area as show in FIG. 11.

The cross-section of the device 410 for the fifth embodiment is substantially the same as that described above in FIGS. 3, 5A, 5B, 7A, and/or 7B for the prior embodiments. For example, the cross-sectional shape of the frame is non-limiting, and the frame may be comprised of a buoyant or non-buoyant material. In the latter case, the device may include flotation devices such as buoys (not shown) attached to frame to allow frame to float. The frame may be positioned on or below the surface of the water. In addition, a scrubber or a plurality of scrubbers segments may be provided along the frame. Preferably, the scrubbers, such as brushes, extend along 50% to 100% of the periphery of the frame such that the brushes engage a majority of the horizontal cross-section of the boat hull, e.g., the waterline section or just below the waterline. The angle of the scrubbers may also be adjustable in relation to the shape of the boat hull or the position of the device in the water.

Looking at FIGS. 10-11, the frame 412 is typically held in position in relation to dock 454 by mooring system 456. The mooring system 456 is similar to the prior embodiments. In general, one or more mooring lines 460 connect the boat docking and cleaning device 410 to the dock 454 and/or pilings 458 at various attachment points 462.

The operation of the boat docking and cleaning device is similar to the prior embodiments. Looking to FIG. 10, the mooring lines 460 of mooring system 456 are adapted to allow the frame 412 to be positioned in a desired location relative to the dock 454.

As shown in FIG. 10, for a docking operation, the frame 412 is in an “open” position. In the “open” position, the frame sections 412A-H form a generally V-shaped docking area 430. The opened end of the V-shaped docking area provides an entrance to docking area 430 through which a boat 428 may pass. As the bow of the boat 428 approaches and contacts the device 410, the scrubbers 450 mounted to frame sections 412A-H resiliently urge and guide the boat 428 into the docking area 430. As the boat 428 advances, the scrubbers 450 continue to urge and align the boat 428 into the docking area 440 until the bow is adjacent to the frame sections 412D and 412E. Once the bow of the boat 428 contacts the frame sections 412D and 412E, the elongated members 420A, 420B are moved or swung toward each other and held in contact with the boat hull. In addition, the frame section 412I is moved toward frame section 412A about movable joint 480, thereby placing the device 410 in a “closed position.” The second ends 424A, 424B of the elongated members 420A, 420B are held in contact with one another by the engaging latches 432A, 432B. Other suitable connection devices include hook and loop fasteners, ropes, clips, ties, and even velcro.

As shown in FIG. 11, in the “closed” position, the frame 412 forms the enclosed docking area 430, holding the boat 428 in position. The boat hull is continuously in contact with scrubber 450 on the frame 412 of the device 410. The motion of the water causes frictional scrubbing action to continuously clean the periphery of the boat hull at the waterline—including the sides, bow, and stern—all while the boat 428 is in the water.

When undocking the boat 428 from docking area 430, the latches 432A, 432B are disengaged and frame section 412I is moved to form an opening between the elongated member 420A, 420B. The boat 428 then exits from docking area 430 by moving the stern between the opening formed by elongated member 420A, 420B. The scrubbers 450 on frame sections 412A-H help urge and guide the boat 428 out of the docking area 430 until the boat 428 is clear of the device 410.

Sixth Exemplary Embodiment

Referring to FIGS. 14 and 15, a combination docking and cleaning device in accordance with a sixth exemplary embodiment of the present invention is designated generally by the number 510. Like the second embodiment, the device 510 comprises a frame 512 having a base section 514 having ends 518A, 518B attached to two elongated members 520A, 520B. Like the fifth exemplary embodiment, the elongated member 520A conforms to the shape of the hull of a boat at the waterline and is comprised of a plurality of frame sections 512A-D, and the elongated member 520B conforms to the shape of the hull of a boat at the waterline and is comprised of a plurality of frame sections 512E-H. Although the device 510 is illustrated as having eight frame sections 512A-512H, it is within the scope of this invention for the quantity of frame sections to vary. The frame sections may be the same or different in size, shape, and overall construction.

The device 410 of the fifth exemplary embodiment is designed as “bow-first,” while the device 510 of the sixth exemplary embodiment is designed as “stern-first” when docking. FIG. 14 illustrates the docking and cleaning device 510 in an “open” position with a boat 528 positioned therein. FIG. 15 illustrates the docking and cleaning device in a “closed” position with the same boat 528 positioned therein. A shown in both FIGS. 14 and 15, the base section 514 is generally shaped to correspond to the stern of the boat 528. The overall shape of the frame 512 is shaped so that once the boat 528 is docked, the shape of the frame 512 generally conforms to the shape of boat hull at the waterline.

As shown in FIGS. 14 and 15, the frame 512 includes two elongated members 520A, 520B having first ends 522A, 522B and second ends 524A, 524B. The first elongated member 520A is comprised of fixedly but adjustably connected frame sections 512A-D. The second elongated member 520B is comprised of fixedly but adjustably connected frame sections 512E-H. The elongated member 520A and the elongated member 520B generally curve toward each other so that their shapes correspond to the shape of the hull of the boat 528 when the frame is in a “closed” position.

The methods for connecting the frame sections in device 510 of the sixth embodiment is substantially the same as that described above for the fifth embodiment. It is preferably that each of the frame sections 512A-D and 512E-H are held in a substantially fixed position. It will be apparent that there may be some play or give at the connections, however, when for example, rope is used to tie the frame sections together.

In this embodiment, as in the second embodiment discussed above, the first ends 522A, 522B of elongated members 520A, 520B are movably attached (preferably pivotably attached) to ends 518A, 518B of the base section 514 respectively at movable joints 526A, 526B. The second ends 524A, 524B of elongated members 520A, 520B are adapted to move or swing toward and away from each other about movable joints 526A, 526B. This permits docking of the boat 528 as generally illustrated in FIGS. 14 and 15. As shown in FIG. 15, the second ends 524A, 524B are removably connected to each other to form the enclosed docking area 530.

The cross-section of the device 510 for the sixth embodiment is substantially the same as that described above in FIGS. 3, 5A, 5B, 7A, and/or 7B for the prior embodiments. For example, the cross-sectional shape of the frame is non-limiting, and the frame may be comprised of a buoyant or non-buoyant material. In the latter case, the device may include flotation devices such as buoys (not shown) attached to frame to allow frame to float. The frame may be positioned on or below the surface of the water. In addition, a scrubber or a plurality of scrubbers segments may be provided along the frame. Preferably, the scrubbers, such as brushes, extend along 50% to 100% of the periphery of the frame such that the brushes engage a majority of the horizontal cross-section of the boat hull. e.g. the waterline section or just below the waterline. The angle of the scrubbers may also be adjustable in relation to the shape of the boat hull or the position of the device in the water.

Looking at FIGS. 14 and 15, the frame 512 is typically held in position in relation to the dock 554 by a mooring system 556. The mooring system 556 comprises one or more mooring lines 560 to connect the device 510 to the dock 554 and/or pilings 558 at various attachment points 562.

The operation of the boat docking and cleaning device is similar to the prior embodiments. Looking to FIG. 14, the mooring lines 560 of the mooring system 556 are adapted to allow the frame 512 to be positioned in a desired location relative to the dock 554.

As shown in FIG. 14, for a docking operation, frame 512 is in an “open” position. In the “open” position, the frame 512 forms a generally U-shaped docking area 530. The opened end of the U-shaped docking area provides an entrance to the docking area 530 through which the boat 528 may pass. As the stern of a boat 528 approaches and contacts the device 510, scrubbers 550 mounted on elongated members 520A, 520B resiliently urge and guide the boat 528 into the docking area 530. As the boat 528 advances, the scrubbers 550 continue to urge and align the boat 528 into the docking area 540 until the stern of boat 528 contacts the base section 514. Once the stern of the boat 528 contacts base section 514, elongated members 520A, 520B are moved or swung toward each other and held in contact with the boat hull by engaging latches 532A, 532B, placing device 510 in the “closed” position.

As shown in FIG. 15, in the “closed” position, frame 512 forms enclosed docking area 530, holding the boat 528 in position. The boat hull is continuously in contact with scrubber 550 on frame 512 of device 510. The motion of the water causes a frictional scrubbing action to continuously clean the periphery of the boat hull at the waterline—including the sides, bow, and stern—all while the boat 528 is in the water.

When undocking the boat 528 from docking area 530, latches 532A, 532B are disengaged and elongated members 520A, 520B are moved to form an opening between elongated members 520A, 520B. The boat 528 then exits from docking area 530 by moving the bow between the opening formed by elongated members 520A, 520B. The scrubbers 550 on elongated members 520A, 520B help urge and guide the boat 528 out of the docking area 530 until the boat 528 is clear of the device 510.

Seventh Embodiment

Referring to FIG. 16, a combination docking and cleaning device in accordance with a seventh exemplary embodiment of the present invention is designated generally by the number 610. The device is generally shown in a “closed” position with a boat 628 positioned therein. The device 610 of the seventh exemplary embodiment differs from the prior embodiments in that there is a line or rope 621 attached to each end of to the base section 614 that holds the boat in contact with the base section 614. Thus, the frame 612 of the docking and cleaning device 610 contacts the boat at about 50% to 60% of the periphery of the boat hull at the waterline when the device is in the “closed” position.

More specifically, the device 610 comprises a frame 612 and the line or rope 621. The frame 612 comprises a base section 614 which is generally V-shaped and comprises first and second members 614A, 614B, which converge and join at apex 616 at one end and extend and bow outwardly from apex 616 to ends 618A, 618B. It will be appreciated that the first and second members 614A, 614B of the base section 614 may be fixedly or movably connected (e.g., pivotably connected) at apex 616.

The cross-section of the device 610 for the sixth embodiment can be constructed as set forth in any one of the prior embodiments, e.g., in FIGS. 3, 5A, 5B, 7A, and/or 7B. Further, the frame may be constructed of one or more frame sections, and the scrubbers may be comprised of one or more scrubber segments. The frame may also be constructed of one or more elongated members attached to optional base section as discussed above.

Looking at FIG. 16, the frame 612 is typically held in position in relation to dock 654 by mooring system 656. The mooring system 656 is similar to the prior embodiments, i.e., one or more mooring lines 660 connect the boat docking and cleaning device 610 to the dock 654 and/or pilings 658 at various attachment points.

The operation of the boat docking and cleaning device 610 is similar to the prior embodiments. For a docking operation, the boat docking and cleaning device 610 is placed in the “open” position where line 621 is removed from the one end 618A, 618B of the base section 614 to provide an opening or entrance to docking area 630 through which a boat 628 may pass. As the bow of a boat 628 approaches and contacts device 610, the scrubbers 650 resiliently urge and guide the boat 628 into the docking area 630. As the boat 628 advances, the scrubbers 650 continue to urge and align the boat 628 into the docking area 630 until the bow is adjacent apex 616. Once the bow of the boat 628 is adjacent apex 616, the line or rope 621 is moved around the stern of the boat 628 and reaffixed to base section 614 at the end 618B.

As shown in FIG. 16, in the “closed” position, the frame 612 together with the rope or line 621 forms the enclosed docking area 630, holding the boat 628 in position. The boat hull is continuously in contact with scrubber 650 on frame 612 of device 610. The motion of the water causes frictional action to continuously clean about 50 to 60% of the periphery of the boat hull at the waterline—all while the boat 628 is in the water. The boat 628 may be undocked by reversing the steps above.

It will be appreciated that although the seventh embodiment illustrates boat docking a cleaning device having a frame which is adapted to receive the bow of the boat first, similar devices which receive the stern first are within the scope of the present invention. In such embodiments, the frame may be a single unitary member shaped to correspond to the stern of the boat or alternatively the frame may be comprised of movable elongated members, such as that illustrated in FIGS. 4 and 5, although truncated in length and attached together using a rope. Such devices would still be capable of cleaning a substantial portion of the boat hull at the a horizontal cross section (e.g., a water line cross section), although in general devices having scrubbers which engage close to 100% of boat hull at the water line are most preferred.

From the foregoing, it will be seen that this invention is one well adapted to attain all ends and objectives hereinabove set forth, together with the other advantages which are obvious and which are inherent to the invention. Since many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matters herein set forth or shown in the accompanying drawings are to be interpreted as illustrative, and not in a limiting sense. While specific embodiments have been shown and discussed, various modifications may of course be made, and the invention is not limited to the specific forms or arrangement of parts and steps described herein, except insofar as such limitations are included in the following claims. Further, it will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. Thus, for example, combinations of the elongated members, base section, scrubbers, scrubber segments, frame segments, motorizing devices, are contemplated by and are within the scope of the claims.
