Description

BACKGROUND OF THE INVENTION

This invention relates to a storage unit for a watercraft and, in particular, to an under-deck storage unit that in one application can be used for a pontoon boat.
It is desirable to have a place on a watercraft to store gear and other items. One such storage place that is often utilized is under the seats. In addition, many hulled boats typically have some type of under-deck storage in the hull area. Fewer options have been available for under-deck storage in a pontoon boat where there is usually only a frame and pontoons beneath the deck.
One prior art under-deck storage has been available for pontoon boats having three pontoons. In this version, a hole is cut in the middle pontoon and a rectangular flange welded thereabout. An opening is made in the frame of the pontoon boat with a rectangular framing support extending around and mounted to the flange around the opening in the middle pontoon. An opening covered by a hatch is placed in the deck over the rectangular frame and the opening in the pontoon so that the hatch may be lifted and gear stored in the middle pontoon.
As no under-deck storage has previously been available for pontoon boats with only two pontoons, it is an object of the subject invention to provide an under-deck storage unit that in one application can be used for a pontoon boat having only two pontoons.

Referring now to FIG. 1, a watercraft is generally indicated as 10. In the embodiment shown, watercraft 10 is a pontoon-style boat having a deck, generally indicated as 12; a pair of pontoons 14; a plurality of seats, generally indicated as 16; and a railing structure, generally indicated as 18, all of which are known. Located in and extending through deck 12 is an opening 20, and a hatch 22 is provided for covering opening 20. Hatch 22 may be either completely removable or attached with a hinge to deck 12 to provide access for storing gear and other items in a storage unit in accordance with the subject invention that is located beneath opening 20, as is discussed in further detail below.
Now referring to FIGS. 2 and 3, a frame, generally indicated as 24, is shown. Frame 24 supports deck 12, and pontoons 14 are mounted to frame 24 so that watercraft 10 will float in a body of water 28 with respect to a waterline 29 of the body of water (FIG. 3). A storage unit, generally indicated as 32, is also mounted to and supported by frame 24.
In the embodiment shown, frame 24 has a plurality of structural members, such as aluminum C-channels, including longitudinal members 34 a-34 d and lateral members 36 a-36 g. Structural members 34 a and 34 b run generally parallel to pontoons 14 along the port side of watercraft 10, and structural members 34 c and 34 d extend parallel to pontoons 14 along the starboard side of watercraft 10. Lateral structural members 36 a-36 g are spaced along longitudinal structural members 34 a-34 d from the bow of watercraft 10 to the stern, respectively.
Frame 24 also includes an internal rectangular frame section, generally indicated as 38, that forms the support for mounting and provides an opening in the frame for storage unit 32. Lateral structural members 36 d and 36 e form the forward and rearward ends, respectively, of rectangular frame section 38, and the sides are formed by a pair of shortened longitudinal side members 40 a, 40 b. Side members 40 a, 40 b are reinforced by shortened lateral structural members 42 a, 42 b, respectively. Lateral structural member 42 a extends from longitudinal structural members 34 a and 34 b to side member 40 a, and lateral structural member 42 b extends from longitudinal structural members 34 c and 34 d to side member 40 b. The structural members are welded, bolted or otherwise attached together with known fastening mechanisms in the configuration shown in FIG. 2.
Now referring to FIGS. 4-6, under-deck storage unit 32 is shown in greater detail. Under-deck storage unit 32 has a generally rectangular configuration and includes a front end, generally indicated as 50; a rear end, generally indicated as 52; a bottom, generally indicated as 54; sides 55 a and 55 b and an upper mounting end, generally indicated as 56. Front end 50 of storage unit 32 has a radiused portion 60 extending across thereof for reasons discussed below. Rear end 52 of under-deck storage unit 32 consists essentially of a generally vertical wall 62, and bottom 54 consists primarily of a generally flat horizontal underside 64, and further includes a trough, generally indicated as 66, running longitudinally along the central portion of bottom 54. Trough 66 has a generally radiused cross-section that varies in depth and gradually increases in depth from the front end 50 towards the rear end 52 of under-deck storage unit 32. A drain hole or aperture 68 may be placed at the deepest portion of trough 66. A plug (not shown) may be provided to releasably close drain hole 68. Also, underside 64 may have a slight slope towards trough 66 for draining any water that may enter the storage unit into the trough and out drain hole 68.
Upper mounting end 56 of under-deck storage unit 32 includes a generally rectangular opening, generally indicated as 70; a front block or enlarged portion 72; a rear block or enlarged portion 74; and four side blocks or enlarged portions 76 a-76 d, with two side blocks on each side of and straddling opening 70. Channels are located between each of the blocks to receive respective structural members of frame 24. A front channel 80 is located between front block 72 and side blocks 76 a, 76 c, and a rear channel, generally indicated as 82, is located between rear block 74 and side blocks 76 b, 76 d. In addition, a pair of intermediate channels, generally indicated as 84 a and 84 b, are located between blocks 76 a, 76 b and 76 c, 76 d, respectively. At the base of each channel 80, 82, 84 a and 84 b is a mounting surface 90 a, 90 b, 90 c, and 90 d, respectively, which can be placed against the respective structural members of frame 24 when under-deck storage unit 32 is mounted to the frame, as shown in FIG. 2. The sides of the channels have inclined surfaces that slope up and away from the mounting surfaces in a generally V-shaped configuration so that the top of the channel is wider than the bottom thereof adjacent the mounting surfaces. Also located at upper mounting end 56 of under-deck storage unit 32 is a rectangular mounting flange, generally indicated as 92, including a plurality of mounting holes 94 for mounting the under-deck storage unit to structural members 40 a, 40 b, with bolts 96 and nuts 98 (FIG. 7), as discussed in further detail below.
One method of manufacturing the under-deck storage unit of the subject invention is through a rotational-molding process so that the storage unit is made of a plastic/polymer material as a single unitary piece. Another advantage of manufacturing the storage unit with this method is that the enlarged portions 72, 74, and 76 a-d may be hollow and provide buoyancy to the storage unit in the event that it is dropped into or becomes dislodged in the water.
To assemble the under-deck storage unit to the frame in accordance with the subject invention, frame 24 is cut and assembled using known methods of welding and/or fasteners, to provide rectangular frame section 38 therein. Rectangular frame section 38 is formed by facing the open side of C-channels structural members 36 d, 36 e, 40 a, and 40 b outward away from the central portion of rectangular frame section 38. As shown in FIGS. 2, 7, and 8, under-deck storage unit 32 is fitted up against rectangular frame section 38 so that front block 72 is located in front of structural member 36 d and rear block 74 is located behind structural member 36 e. Side blocks 76 a-76 d are placed between structural members 36 d and 36 e with side blocks 76 a and 76 b straddling lateral structure member 42 a and side blocks 76 c and 76 d straddling lateral structural member 42 b. Furthermore, storage unit 32 is fit against frame 24 so that lateral structural member 36 d is located in front channel 80 and up against mounting surface 90 a, and lateral structure member 36 e is placed in rear channel 82 and against mounting surface 90 b. Lateral structure members 42 a and 42 b are located in intermediate channels 84 a and 84 b and against mounting surfaces 90 c, 90 d, respectively. When under-deck storage unit 32 is thusly placed and located, it can then be attached to frame 24 by affixing rectangular mounting flange 92 to the bottom flanges of lateral structural members 42 a and 42 b using bolts 96 inserted through mounting holes 94 and securing the bolts with nuts 98.
In operation, under-deck storage unit 32 can be used to store gear and other material in watercraft 10 by lifting or removing hatch 22 and placing the gear through opening 20 in deck 12 and into access opening 70. When watercraft 10 is in motion or if there is wave action, radiused portion 60 in front end 50 of under-deck store unit 32 aids breaking waves and to decrease splashing. For any water that may gain entry into under-deck storage unit 32, trough 26 and drain aperture 68 provide a drainage path. It should be appreciated that the slope in the bottom of trough 66 guides any water in the under-deck storage unit to drain aperture 68. A plug may be placed in drain aperture 68 to prevent water from entering storage unit 32 therethrough.
It should also be appreciated that in the embodiment disclosed, under-deck storage unit 32 as mounted to watercraft 10 is located at a level above waterline 29 to reduce drag caused therefrom and to help reduce splashing. It should also be appreciated that sealing members or adhesives may be used in the fit-up of under-deck storage unit 32 to watercraft 10 to help preclude any water that may splash around the top end of the storage unit from entering into the interior portion thereof.
While the invention has been taught with specific reference to these embodiments, one skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and scope of the invention. For example, the shape may be changed to other than rectangular, and the frame section for mounting the storage unit can be varied to complement the storage unit shape. Also, the storage unit may be located at any other desired position beneath the deck and between the pontoons. In addition, the storage unit of the present invention may be used on other types of watercraft in addition to pontoon boats. The described embodiments are to be considered, therefore, in all respects only as illustrative and not restrictive. As such, the scope of the invention is indicated by the following claims rather than by the description.
