Description
WATERCRAFT STABILIZER
RELATED APPLICATION
[0001] This application claims priority to U.S. Provisional Application No. 60/719,935, filed September 23, 2005.
BACKGROUND OF THE INVENTION
[0002] This invention relates to watercraft and, more particularly, to a stabilizer assembly for canoes that is lightweight, strong, and easy to assemble.
[0003] Various types of watercraft such as canoes, kayaks, and the like, are inherently unstable and prone to tipping during use.
[0004] There are several types of devices available to help stabilize the watercraft. A sponson, for example, typically includes inflatable sections that are strapped to a hull of the watercraft to provide buoyant stabilization. Disadvantageously, the inflatable sections are prone to puncture during use of the watercraft, and often do not provide a desired amount of stabilization.
[0005] Other stabilizer devices include heavy frames that attach to sides of the watercraft and extend into the water. The frame supports floats that stabilize the watercraft and move across the water surface as the watercraft moves. Disadvantageously, these types of devices include many different frame pieces to assemble, are heavy, and are difficult to attach to the watercraft. Further, the relatively heavy weight offsets the stabilization benefits of the float, and the frame is susceptible to bending during assembly or during use.
[0006] Accordingly, a lightweight and strong stabilizer assembly that is easy to assemble is needed.
SUMMARY OF THE INVENTION
[0007] An example watercraft stabilizer assembly includes a frame comprising a plurality of frame members connected together and a plurality of floats received on the frame. In one example, the frame includes two frame members and in another example the frame includes four frame members. At least one clamp secures the frame to a watercraft, such as a canoe. The clamp comprises clamp members that are securable together such that the frame and a portion of the watercraft are held together between the clamp members.
[0008] In another aspect, the watercraft stabilizer assembly includes a two-point support that secures the frame to the watercraft. In one example, the two point support includes a U-shaped member that supports the frame at a first point and a saddle member that supports the frame at a second point.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0020] Figure 1 illustrates selected portions of an example watercraft 10, such as a canoe. The watercraft 10 includes a stabilizer assembly 12 that stabilizes the watercraft 10 to provide resistance to tipping.
[0021] In this example, the stabilizer assembly 12 includes a frame 14 having a first frame member 16a and a second frame member 16b that are secured together to form the frame 14. Floats 18 are received onto and supported by the frame 14. In the illustrated example, the frame 14 of the stabilizer assembly 12 is secured at four illustrated locations to the edges 20 of the watercraft 10 using clamps 22.
[0022] Referring to Figure 2, the float 18 is made of a buoyant material such as foam. In one example, the buoyant material is polystyrene, polyethylene, or other type of foam. In this example, the float 18 comprises a solid body 24 having an opening 26 extending along a longitudinal axis A of the float 18. In one example, the opening 26 is drilled through the solid body 24.
[0023] Referring to Figure 3, each float 18 is slidably received onto the first frame member 16a. The frame members 16a and 16b have a generally uniform cross-section. In this example, the frame members 16a and 16b are nominally round. In this example, the ends 40 of the first frame member 16 a have a reduced diameter cross-section that permits the ends 40 of the first frame member 16a to fit within corresponding ends 42 of the second frame member 16b.
[0024] In one example, the reduction in the cross-section of the ends 40 is achieved using a crimping process. In another example, the reduction in cross-section is achieved using a swaging process. Given this description, one of ordinary skill in the art will be able to recognize other methods of achieving a reduced cross-section for fitting the frame members 16a and 16b together.
[0025] The ends 40 are received into the corresponding ends 42 of the second frame member 16b and form a joint 41 there between that secures the frame members 16a and 16b together. In the illustrated example, the floats 18 fit tightly between the frame members 16a and 16b, which provides the benefit of reduced float 18 movement during use of the stabilizer assembly 12.
[0026] In one example, reducing the cross-sections of the ends 40 permits an interfere fit with the inner diameter of the corresponding ends 42 of the second frame
member 16b to provide a tight fit. This provides the benefit of tightly securing the first frame member 16a and the second frame member 16b together during use of the stabilizer assembly 12 and further provides a simplified assembly method.
[0027] Referring to Figures 4-5, once the frame 14 is assembled, it is secured to the edges 20 of the watercraft 10. The clamps 22 include a U-shaped member 52 having threaded portions 54 that receive nuts 62 to secure the frame 14 to the edges 20. A saddle member 57 includes a curved portion 59 that cradles the frame 14 and a support edge 61 (i.e. a pivot surface). A resilient lip 58 includes openings 60 that receive the threaded portions 54 of the shaped member 52. The nuts 62 are threaded onto the threaded portions 54 and tightened to compress the resilient lip 58 against the saddle member 57. In the illustrated example, the edge 20 of the watercraft 10 includes an inside lip 64 such that the nuts 62 are assembled inside of the watercraft.
[0028] The tightening of the nuts 62 secures the frame 14 between the inside lip 64 and the U-shaped member 52. As the nuts 62 are tightened, the support edge 61 of the saddle member 57 presses against the underside of the inside lip 64 to pivot the saddle member 57 upwards (relative to Figure 5). This pushes the curved portion 59 upwards against the frame 14 as the U-shaped member 52 forces the frame 14 downwards to provide a two- point support that evenly supports the frame 14 and keeps the frame 14 relatively parallel to the inside lip 64. Thus, the clamp 22 provides an easy to assemble method of securing the stabilizer assembly 12 to the watercraft 10. Further, the resilient lip 58, which compresses during tightening of the nuts 62, provides a constant tension on the U-shaped member 52 to maintain a securing force on the frame 14. This provides a benefit of maintaining a tight clamping force against vibration or other environmental factors acting to loosen the clamp 22.
[0029] Figure 6 illustrates the shape of the frame 14 according to the cross section shown on Figure 1. In this example, the frame 14 extends at an angle α downwards toward a water surface 74. In one example, the angle α is about 30°. An angle of 30° allows the frame 14 to extend away from the watercraft 10 and provides leverage to stabilize the watercraft 10. If the angle α is made too large such that the portions of the frame 14 that extend downwardly toward the water surface 74 are closer to the watercraft 10, the stabilization effect may be less. If the angle α is made smaller than 30° such that the portions of the frame that extend toward the water surface 74 are farther away from the watercraft 10, the frame 14 may interfere with navigation of the watercraft 10 through relatively narrow waterways.
[0030] Figure 7 illustrates the frame 14 according to the cross-section shown in Figure 1. In the illustrated example, the frame 14 bends at an angle θ. In one example, the angle θ is about 90°. An angle of about 90° positions the frame 14 and float 18 approximately parallel to the water level 74.
[0031] In another example, the frame 14 is made of a %" metal conduit. In one example, the metal is a relatively lightweight and strong metal, such as aluminum, titanium, magnesium or other lightweight metal. The thickness of metal conduit is relatively thin to minimize the weight of the frame 14. The combination of the relatively small diameter of the conduit, the relatively thin thickness, and relatively strong and lightweight material provides the benefit of a lightweight and strong stabilizer assembly 12.
[0032] In one example, the stabilizer assembly 12 can support a weight of an average adult without bending significantly. Further, assembling the frame 14 from only two frame members 16a and 16b minimizes the number of frame parts needed to assemble the stabilizer assembly 12, which is a drawback of prior stabilizer systems. Thus, a user of the stabilizer assembly 12 can easily assemble the frame 14 and secure it to a watercraft 10 and likewise disassemble the stabilizer assembly 12 when not in use.
[0033] In the above examples, the frame 14 includes only two frame members 16a and 16b, however, in another example shown in Figure 8, the frame 14 includes four frame members 16c, 16d, 16e, and 16f that are secured together in the same manner as the frame members 16a and 16b using reduced cross-section ends 40 that fit within corresponding ends 42. Given this description, one of ordinary skill in the art will be able to recognize which ends of the frame members 16c, 16d, 16e, and 16f to form with reduced cross-sections to meet their particular needs.
[0034] In another example shown in Figure 9, the frame 14 includes six frame members 16g, 16h, 16i, 16j, 16k, and 161 that are secured together in the same manner as the frame members 16a and 16b using reduced cross-section ends 40 that fit within corresponding ends 42. In this example, the frame members 16i and 16j are linear pieces that extend across the width of the watercraft 10 and are clamped to the edges 20 of the watercraft 10 using the clamps 22. The frame members 16g and 16h are secured together with one of the floats 18 and then secured to the frame members 16i and 16j. The frame members 16k and 161 are likewise assembled. Thus, the clamps 22 and linear frame members 16i and 16j may remain assembled on the watercraft 10 even when the floats 18 and other frame members
16g, 16h, 16k, and 161 are removed, which eliminates the need to completely disassemble and remove the entire stabilizer assembly 12 for storage or when the watercraft 10 is transported, for example.
[0035] Referring to Figure 10, the joints 41 between any of the frame members 16a-l in the above examples optionally include a quick release mechanism 84 (i.e., a locking mechanism) to secure the frame 14 together. For illustration, the frame members 16d and 16e are shown.
[0036] In this example, the quick release mechanism 84 includes a button 86 located at least partially within a recess 88 of the frame member 16d. The recess 88 includes a notch 90 that defines a range of travel 92 of the button 86. A resilient member 94, such as a spring, is located between the button 86 and a wall 96 of the frame member 16d. The resilient member 94 biases the button upwards in the figure through an opening 98 in the frame member 16d. The button can be manually moved against the biasing force of the resilient member 94 such that the button 86 retracts into the recess 88. The retraction allows the frame member 16d to be inserted into the frame member 16e.
[0037] In this example, the frame member 16e includes an opening 100 that corresponds to the button 86. When the button 86 is aligned with the opening 100, the resilient member 94 moves the button 86 through the opening 100 to lock the frame members 16d and 16e together. To disassemble the frame members 16d and 16e, the button 86 is actuated against the biasing force of the resilient member 94 into the recess 88 such that the frame member 16d can be slidably removed from the frame member 16e. Given this description, one of ordinary skill in the art will recognize alternative arrangements and quick release mechanisms to meet their particular needs.
[0038] Although a preferred embodiment of this invention has been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied to determine the true scope and content of this invention.
