DETAILED DESCRIPTION OF THE INVENTION

The embodiments discussed below are not intended to be exhaustive or limit the invention to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in the art may utilize their teachings.
A watercraft, generally indicated as 10, is shown in FIG. 1, and in this embodiment, watercraft 10 is a pontoon boat. Watercraft 10 includes a frame, generally indicated as 12, an engine, generally indicated as 14, pontoons 16, and deck 18. Watercraft 10 also includes a plurality of rails 20 and panels 22 supported by frame 12 and deck 18. Rails 20 are positioned above and below panels 22 to form a boundary around an outer periphery of deck 18 to safely surround passengers on watercraft 10.
A cross-sectional view of a prior art embodiment of one rail, generally indicated as 19, is shown in FIG. 2. Rails 19 are used similarly to rails 20 as shown in FIG. 1 to secure panels 22 to the watercraft to form an outer boundary of the watercraft. Each rail 19 is constructed of an extruded metallic tube and includes a rail member 17 having a substantially square profile. Rail 19 also includes an extension 15 coupled to one side of rail member 19. This configuration of rail 19 is commonly called a “Q tube.” Extension 15 includes a pair of teeth 21. A receiving area, generally indicated as 23, is formed between extension 15 and rail member 17. In FIG. 2, rail 19 is shown in the unassembled orientation. In use, a panel, such as panel 22 in FIG. 1, is positioned in receiving area 23, and extension 15 is bent or crimped toward rail member 17 to secure the panel in receiving area 23 in position. Teeth 21 engage the panel when extension 15 is crimped.
A partial cross-sectional view of an embodiment of upper and lower rails 20 in accordance with the present invention with one panel 22 positioned between is shown in FIGS. 3 and 4. Upper and lower rails 20 are identical with respect to form and function and differ only in orientation. Panel 22 is shown in partial for simplicity, and it should be understood that opposite ends are also substantially identical and only differ in orientation.
As shown in FIG. 3, each rail 20 includes a rail member 24, an extension 26, and a recess or recessed area 30. In this embodiment, rail 20 is an extruded aluminum tube. In other embodiments (not shown), rail 20 may be constructed of another metallic material, a non-metallic material, or any other suitable material. Rail member 24 has a substantially square profile and a hollow central region. Rail member 24 includes a side, generally indicated as 25, from which an extension 26 extends. Side 25 and extension 26 form a receiving area, generally indicated as 29, for receiving an end of panel 22, as will be described herein. Extension 26 extends from side 25 of rail member 24 and includes an interlocking or engaging portion 28, which is shown as a tab, positioned at one end of extension 26. A recessed area or recess 30 is formed in side 25 of rail member 24. As shown in FIG. 3, in this embodiment, recessed area 30 extends about half of the length of side 25.
Panel 22 includes a panel member 32, which is continuous between an upper end 31 and a lower end 33. Upper and lower ends 31 and 33 each include an interlocking or engaging portion 34, which is shown as a tab that extends substantially perpendicularly from panel member 32. In this embodiment, panel 22 is constructed of polycarbonate. Polycarbonate is dent- and scratch-resistant and has excellent thermal expansion, toughness, and forming capabilities. Additionally, polycarbonate has heat deflection properties and can be produced in a wide variety of colors, which may reduce the need for further processing such as painting. Supplemental components, such as ultraviolet blockers and stabilizers, may be added to polycarbonate to optimize the polycarbonate for the desired application. It should be understood that panel member 22 may be constructed from a polymer-based material, a non-metallic material, or any other suitable material.
It should be appreciated that FIG. 3 shows a preassembled position, where panel 22 is shown poised for interconnection to rails 20. In this position, upper end 31 and lower end 33 of panel member 32 are positioned in corresponding recessed areas 30, with respective interlocking portions 34 extending in an overlapping manner with interlocking portions 28 of extensions 26.
Referring now to FIG. 4, rails 20 are shown with extensions 26 bent or crimped to secure panel 22 in position between upper and lower rails 20. When extensions 26 are crimped, interlocking portions 28 interlock with respective interlocking portions 34 to secure panel member 32 in recessed areas 30. As shown in FIG. 1, rails 20 and panels 22 extend along the length of watercraft 10. Assembly of the boundary formed by rails 20 and panels 22 generally includes the steps of positioning a panel 22 between upper and lower rail 20, as shown in FIG. 3, and providing a roller or other crimping device (see FIG. 8) configured to bend extensions 26 from the position shown in FIG. 3 into a position to secure panel 22, as shown in FIG. 4.
With reference now to FIGS. 5 and 6, another embodiment will be described. In this embodiment, upper and lower rails, generally indicated as 40, are provided and positioned to cooperate with a panel, generally indicated as 52. Upper and lower rails 40 each include a rail member 42, an extension 44, a recess or recessed area 48, and a receiving area, generally indicated as 50. In this embodiment, recess 48 defines a notch. Panel 52 includes a panel member 54 and interlocking portions 56, which are shown as tabs. Panel 52 is substantially similar to panel 22 with the exception that the orientation of the interlocking portions is reversed relative to the rails 40, that is, interlocking portions 56 are facing towards rails 40 rather than away from rails 40. Rails 40 are similar to rails 20 with the exceptions that extensions 44 do not include interlocking portions and recesses 48 are configured to accept interlocking portions 56 of panel 52.
As shown in assembled view FIG. 6, extensions 44 are bent or crimped, as described above, toward rail members 42 to contact panel member 54 and secure interlocking portions 56 in recesses 48. Interlocking portions 56 interlock with rail members 42 in recesses 48. Extensions 44, interlocking portions 56, and recesses 48 prevent panel 52 from becoming dislodged if a force is applied to flex panel member 54.
Another alternative embodiment of the rail and panel system is shown in FIG. 7. This rail and panel system utilizes rails 19 of FIG. 2 and a non-metallic panel, generally indicated as 70. Rails 19 and panel 70 are shown in an assembled partial cross-sectional view in FIG. 7. As discussed above, rail 19 includes an extension 15 having teeth 21. Non-metallic panel 70 is substantially flat and includes ends 72, which are configured to be positioned in receiving areas 23 (not shown) of rails 19 during assembly. Extensions 15 are then crimped, which is described below, to secure panel 70 in position. Teeth 21 on extensions 15 contact ends 72 of panel 70 to secure panel 70 between rails 19. In this position, non-metallic panel 70 directly contacts rail members 17 and extensions 15.
With reference now to FIG. 8, a method of installing the rail and panel system will be described. The method is shown with the rail and panel system of FIGS. 3 and 4, but the method is equally applicable to the embodiments of FIGS. 5, 6 and 7.
With respect to the manufacturing of the rails themselves, the rails may be extruded from a material such as aluminum. The cross section of rails 20 or 40 is conducive to an extrusion process, as all of the configuration is continuous along its entire length. That is, for instance, in the embodiment shown, rail 20 is designed such that all of the features, including rail member 24, extension 26, interlocking portion 28, and recess 30, are continuous along the entire length of the rail, which may make an extrusion process a suitable means for producing rails 20 or 40.
Once the rails are provided, the panel is provided. In one embodiment, panels 22, 52 may be formed by a molding or extrusion process. The configuration of panels 22, 52 is also compatible for either process. In either case, the panels are formed to include the interlocking portions 34 at the upper and lower ends 31, 33 of panel 22. It should be appreciated that the panels are formed such that the interlocking portions are spaced apart at the proper distance between extensions 26.
Once two rails are positioned as shown in FIG. 3, the panel 22 can be slidably received longitudinally into the receiving areas 29, until the panel 22 is fully installed. At that point, a crimping roller, such as 60 (FIG. 8), which is rotatable about axis A-A, can be used to crimp extensions 26 into place. For example, roller 60 can begin at one end of rail 20 and move longitudinally along the length of rail 20 to roll the extensions from the preassembled position of 26-1, shown in outline form, to the assembled position of 26-2, where interlocking portions 28 overlap and interlock with interlocking portions 34.
Now referring to FIGS. 9 and 10, another alternate embodiment of a rail and panel system is shown. The rail and panel system utilizes upper and lower rails, generally indicated as 80, respectively. Rails 80 may be an extruded aluminum tube or may be constructed using another process or another metallic material, non-metallic material or any other suitable material. Rail member 84 has a substantially square profile and a hollow central region. Each rail member 84 also includes a side, generally indicated as 85, from which an extension 86 extends. Side 85 and extension 86 form a receiving area, generally indicated as 89 (FIG. 9), for receiving an end of a panel, generally indicated as 100, as will be described herein. Extension 86 extends from side 85 of rail member 84 and includes an interlocking or engaging portion 88, which is shown as a tab or a lip, positioned at one end of extension 86. In this embodiment, a recessed area or recess 90 is formed in side 85 of rail member 84. In this embodiment, recessed area 90 extends about one-half of the length of side 85.
Panel 100 includes a panel member 102, which is continuous between an upper end 101 and a lower end 103. Upper and lower ends 101 and 103 each include an interlocking or engaging portion 104, which is shown as a tab or a lip that faces away from rail members 84. In the embodiment shown, interlocking portions 104 form an acute angle with a face of panel member 102. Panel member 102 may be constructed of a polycarbonate or may be constructed from another polymer-based material, a non-metallic material, a metallic material, or other suitable material.
FIG. 9 shows a preassembled position, where panel 100 is shown poised for interconnection to rails 80. In this position, upper end 101 and lower end 103 of panel member 102 are positioned in corresponding recessed areas 90, with respective interlocking portions 104 extending in an overlapping manner, with interlocking portions 88 of extensions 86.
Referring now to FIG. 10, rails 80 are shown with extensions 86 bent or crimped, such as with a crimping roller 60 shown in FIG. 8, to secure panel 100 and positioned between upper and lower rails 80. When extensions 86 are crimped, interlocking portions 88 interlock with respective interlocking portions 104 to secure panel member 102.
While this invention has been described as having an exemplary design, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. For example, most of the embodiments depicted can be manufactured without a recessed area on the rail adjacent the extension. In addition, the shape, size and orientation of the interlocking portion or tabs on the extension and panel can be modified to other suitable forms. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains.
