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 10 is shown in FIG. 1, and in this embodiment, watercraft 10 is a pontoon boat. Watercraft 10 includes frame 12, engine 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 upper and lower rails 19 is shown in FIG. 2. Rails 19 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 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 a panel positioned in receiving area 23 in position. Teeth 21 engage the panel when extension 15 is crimped.
A partial cross-sectional view of another embodiment of upper and lower rails 20 with 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, rail 20 includes rail member 24, extension 26, and 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 25, from which extension 26 extends. Side 25 and extension 26 form a receiving area 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. Recess 30 is formed in side 25 of rail member 24. As shown in FIG. 3, in this embodiment, recess 30 extends about half of the length of side 25.
Panel 22 includes panel member 32 which is continuous between upper end 31 and 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 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 31 and lower 33 ends of panel 32 are positioned in corresponding recesses 30, with interlocking portions 34 extending in an overlapping manner with interlocking portions 28.
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 interlocking portions 34 to secure panel member 32 in recesses 30. As shown in FIG. 1, rails 19 and panels 22 extend along the length of watercraft 10. In this embodiment, rails 19 have been replaced by rails 20. 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 configured to bend extensions 26 from the position shown in FIG. 2 into a position to secure panel 22, as shown in FIG. 4.
With references now to FIGS. 5 and 6, another embodiment will be described. In this embodiment, upper and lower rails 40 are positioned to cooperate with a panel 52. Upper and lower rails 40 include rail members 42, extensions 44, recesses 48, and receiving areas 50. In this embodiment, recess 48 is defined as a notch. Panel 52 includes 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 relative the rails 40 is reversed, that is interlocking portions 56 are adjacent to rails 40 rather than opposing 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 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.
In an alternative embodiment of the rail and panel system shown in FIGS. 3 and 4 and 5 and 6, a rail and panel system including rail 19 of FIG. 2 and non-metallic panel 70 is shown in FIG. 7. Rails 19 and panel 70 are shown in an assembled partial cross-sectional view in FIG. 6. 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 embodiment of FIGS. 5, 6, and 7.
Firstly, with respect to the manufacturing of the rails themselves, the rails 20 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, the rail 20 is designed such that all of the features such as 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 the 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, 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 position of 26-1 to the position of 26-2, where interlocking portions 28 overlap and interlock with interlocking portions 34.
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. 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.
