This non-provisional application claims the benefit of priority under 35 U.S.C. § 119(e) to U.S. Provisional Patent Application Ser. No. 60/820,926, filed Jul. 31, 2006, which is herein incorporated by reference in its entirety.
TECHNICAL FIELDThis patent document pertains generally to suppressing a rolling or pitching motion of a boat. More particularly, but not by way of limitation, this patent document pertains to a self-leveling pontoon boat assembly.
BACKGROUNDBoats, such as pontoon boats, often experience rolling and pitching motions due to waves or unbalanced vertical loads (e.g., when passengers board a boat). These rolling and pitching motions may cause passengers or gear located on, or boarding, a surface of the boat to be thrown around, possibly resulting in injury to one or more of the passengers.
OverviewThe present inventor has recognized, among other things, an unmet need for suppression of roll, pitch, or gravitation force (“g-force”) experience by a subject on a deck of a pontoon boat assembly.
In Example 1, a pontoon boat assembly comprises two or more pontoons; at least one deck disposed above the two or more pontoons, the deck being rotatably movable relative to the two or more pontoons; and an actuating means to rotate the at least one deck in response to a motion of at least one of the pontoons such that the deck remains substantially level.
In Example 2, the pontoon boat assembly of Example 1 is optionally configured such that the at least one deck includes an upper deck and a lower deck, the lower deck disposed between the upper deck and the two or more pontoons.
In Example 3, the pontoon boat assembly of Example 2 is optionally configured such that the upper deck is independently suspended above the two or more pontoons.
In Example 4, the pontoon boat assembly of Example 2 is optionally configured such that the actuating means is disposed between the upper deck and the lower deck.
In Example 5, the pontoon boat assembly of Example 2 optionally comprises at least one curved track support member disposed between the upper deck and the lower deck.
In Example 6, the pontoon boat assembly of Example 5 is optionally configured such that the actuating means includes a mechanical gyro having one or more struts and one or more wheels attached to an end of the struts, the one or more wheels configured to rest and move along the at least one curved track support member.
In Example 7, the pontoon boat assembly of Example 2 is optionally configured such that the actuating means includes an electronic gyro configured to provide sensed electrical information to a controller.
In Example 8, the pontoon boat assembly of Example 7 optionally comprises two or more piston devices positioned between the upper deck and the lower deck, the two or more piston devices configured to adjust in response to a rolling or pitching motion of the two or more pontoons using an actuating signal provided by the controller.
In Example 9, the pontoon boat assembly of Example 8 is optionally configured such that the two or more pistons comprise at least one of air or hydraulic pistons.
In Example 10, the pontoon boat assembly of Example 7 is optionally configured such that the electronic gyro is disposed adjacent a middle portion of the at least one deck.
In Example 11, the pontoon boat assembly of at least one of Examples 1-10 is optionally configured such that the actuating means is disposed between the two or more pontoons.
In Example 12, a method comprises supporting a deck relative to a pair of pontoons using a curved support; and keeping the deck substantially level regardless of a position of the pontoons.
In Example 13, the method of Example 12 is optionally configured such that supporting the deck relative to the pair of pontoons includes supporting an upper deck relative to a lower deck using the curved support.
In Example 14, the method of at least one of Examples 12-13 optionally comprises supporting the deck relative to the pair of pontoons using a mechanical gyro having one or more struts and one or more wheels attached to an end of the struts.
In Example 15, the method of Example 14 is optionally configured such that keeping the deck substantially level regardless of a position of the pontoons includes moving the one or more wheels along the curved support.
In Example 16, the method of Example 15 is optionally configured such that moving the one or more wheels along the curved support includes rotating a first portion of the deck along the curved support to a position near a top of a first pontoon; and moving a second portion of the deck along the curved support to a position distant from a top of a second pontoon.
In Example 17, a method comprises supporting a deck relative to a pair of pontoons using two or more piston devices disposed between the deck and the pontoons; sensing a change in position of at least one pontoon; generating an actuator signal using the sensed change in pontoon position; and causing the two or more pistons to keep the deck substantially level regardless of the positions of the pontoons.
In Example 18, the method of Example 17 is optionally configured such that supporting the deck relative to the pair of pontoons includes using four piston devices, each piston device disposed at a corner portion of the deck.
In Example 19, the method of at least one of Examples 17-18 is optionally configured such that causing the two or more pistons to keep the deck substantially level includes moving at least a first piston in a first direction and moving at least a second piston in a second direction opposite the first direction.
In Example 20, the method of at least one of Examples 17-19 is optionally configured such that causing the two or more pistons to keep the deck substantially level includes suppressing a rolling or pitching force applied to the at least one pontoon.
These and other examples, advantages, and features of the present pontoon boat assembly and methods will be set forth in part in following Detailed Description. This Overview is intended to provide an overview of subject matter of the present patent application. It is not intended to provide an exclusive or exhaustive explanation of the invention. The Detailed Description is included to provide further information about the present patent application.
In the drawings, which are not necessarily drawn to scale, like numerals describe similar components throughout the several views. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
The pontoon boat assemblies discussed herein provide a pontoon boat having a deck that is independently suspended above the pontoons. Advantageously, the deck remains generally level in response to a roll, pitch, or g-force regardless of the position of one or both pontoons.
Through the use of the one or more struts 110, the one or more wheels 112, and the track support members 114, the upper deck 102 is able to move relative to the pontoons 106A, 106B (as shown in phantom). In this way, the pontoon boat assembly 100 is able to suppress roll experienced by subjects located on the upper deck 102 relative to the roll experienced by the pontoons 106A, 106B. For example, when a wave approaches and comes in contact with a longitudinal side of a first pontoon 106A, the upper deck 102 portions nearest the first pontoon 106A may rotate along the track support members 114 to a position near a top of the first pontoon 106A, while the upper deck 102 portions nearest a second pontoon 106B may rotate along the track support members 114 to a position relatively distant from a top of the second pontoon 106B. In this way, the upper deck 102 maintains a generally level orientation regardless of a position of the pontoons 106A, 106B.
Through the use of the one or more electronic gyros 208, the controller 224, and the one or more hydraulic or air pistons 210, for example, the upper deck 202 is able to move relative to the pontoons 206A, 206B, and is thereby able to suppress both roll and pitch of the pontoon boat assembly 200. For example, when a wave approaches and comes in contact with a longitudinal side of a first pontoon 206A, the electronic gyro 208 and controller 224 may together sense and generate an actuator force which is communicated to the one or more hydraulic or air pistons 210. In one such example, the one or more hydraulic or air pistons 210 adjacent the first pontoon 206A may move in one direction, while the one or more hydraulic or air pistons 210 adjacent the second pontoon 206B may move in the opposite direction. In brief, the one or more pistons 210 adjust in such a way that the upper deck 202 maintains a generally level orientation.
