- the present invention relates generally to the field of water park rides. More specifically, the present invention discloses a flotation collar for water park craft.
- Flotation collars have been used for many years in conjunction with water park rides to provide buoyancy and to serve as a bumper.
- the prior art in this field includes collars having a series of baffled chambers integrated within the main body of the collar. However, if a baffled chamber is compromised, that chamber will fill with water and cause the craft to list. This also creates the possibility of capsizing the craft.

Abstract
A flotation collar for a water park craft has a flexible outer wall and an inflatable outer chamber. A number of containment bags within the outer chamber define a plurality of inner chambers containing buoyant material, such as foam, that partially fill the outer chamber.
Description
- 1. Field of the Invention
- The present invention relates generally to the field of water park rides. More specifically, the present invention discloses a flotation collar for water park craft.
- 2. Statement of the Problem
- Flotation collars have been used for many years in conjunction with water park rides to provide buoyancy and to serve as a bumper. The prior art in this field includes collars having a series of baffled chambers integrated within the main body of the collar. However, if a baffled chamber is compromised, that chamber will fill with water and cause the craft to list. This also creates the possibility of capsizing the craft.
- Another prior art approach uses a series of internal bladders that fit within a main body cover. The cover itself is not typically buoyant or air-tight. This approach relies on the bladders to fill the cavity within the cover, create the desired overall shape, and provide buoyancy. Each bladder is like a balloon within the cover. Each bladder is allowed to expand to fill gaps and voids internally, but relies heavily on adjacent bladders for support. If one bladder fails, the adjacent bladders will try to fill the void and therefore often rupture. Unfortunately, this design is plagued with such failures.
- Another prior art approach uses a collar filled with a polymer foam. This approach also tends to fail if the collar chamber is compromised. The foam tends to take on water and will break down from repeated impacts with the walls of the water park ride.
- Thus, a need exists for a flotation collar that can survive a breach in the outer wall of the collar without significant listing.
- 3. Prior Art
- The prior art in this field also includes the following:
Inventor Patent No. Issue Date Francois 4,021,873 May 10, 1977 Marbach 4,360,396 Nov. 23, 1982 Spieldiener et al. European Publ. 0155778 Feb. 26, 1985 Walters et al. 4,520,746 Jun. 4, 1985 Spieldiener et al. 4,696,251 Sep. 29, 1987 Hopkins 5,299,964 Apr. 5, 1994 Salmons 5,331,914 Jul. 16, 1994 Robinson 5,617,808 Apr. 8, 1997 Hempfield et al. 6,371,040 Apr. 16, 2002 - These references show a wide variety of flotation collars and pontoons that are either air-filled or foam-filled. For example, Salmons, Robinson, and Marbach show foam-filled flotation collars or pontoons. Spieldiener et al. and Hopkins show air-filled flotation collars.
- U.S. Pat. No. 6,371,040 (Hemphill et al.) shows a hybrid structure that uses both an inflatable bladder14 and a foam material 18. In particular, the inflatable bladder 14 is surrounded by an annular layer of foam 18. This assembly is covered by a
protective sleeve 22, which may contain reinforcing material such as aramid fibers. - 4. Solution to the Problem
- None of the prior art references discussed above show a flotation collar having the structure of the present invention. In particular, the present invention involves a flotation collar having an inflatable outer chamber that contains a series of containment bags containing a buoyant material, such as foam. Under normal conditions, the outer wall of the flotation collar and the outer chamber protect the foam in the containment bags from mechanical impact or taking on water. In the event the outer chamber fails, the containment bags provide sufficient buoyancy to prevent listing. In addition, the containment bags prevent the foam from taking on water.
- This invention provides a flotation collar for a water park craft that has a flexible outer wall and an inflatable outer chamber. A series of containment bags within the outer chamber define a plurality of foam-filled inner chambers that partially fill the outer chamber.
- These and other advantages, features, and objects of the present invention will be more readily understood in view of the following detailed description and the drawings.
- The present invention can be more readily understood in conjunction with the accompanying drawings, in which:
- FIG. 1 is a perspective view of a
water park craft 10 with aflotation collar 20 incorporating the present invention. - FIG. 2 is a perspective view of the
flotation collar 20. - FIG. 3 is a top plan view of the
flotation collar 20 with thecontainment bags 30 within theouter wall 22 shown in dashed lines. A portion of theflotation collar 20 is shown in cross-section. - FIG. 4 is a top perspective view of a
containment bag 30. - FIG. 5 is a vertical cross-sectional view of the
flotation collar 20 taken along lines 5-5 in FIG. 3. - FIG. 6 is a detail exploded cross-sectional view of filling
valve 37 of acontainment bag 30 - FIGS. 7 through 11 are cross-sectional views of the
flotation collar 20 illustrating the steps of inflating and filling the chambers of theflotation collar 20. - FIG. 12 is a vertical cross-sectional view of an alternative embodiment of the
flotation collar 20. - Turning to FIG. 1, a perspective view is provided showing a
water park craft 10 with aflotation collar 20 incorporating the present invention. FIG. 2 is a perspective view of theflotation collar 20 by itself. Thewater craft 10 can be of any desired shape and size.Many water craft 10 are generally circular and can accommodate a number of passengers in seats arranged in a circular pattern. Theflotation collar 20 extends around the periphery of thewater craft 10 to provide buoyancy and serve as a bumper if the water craft encounters a wall or obstacle. For example, FIGS. 1 and 2 show aflotation collar 20 that is generally annular in shape to surround thewater craft 10. Theflotation collar 20 can be secured to thewater craft 10 by any number of means. For example, the embodiment depicted in FIG. 1 employs a series of elasticized straps. - The
flotation collar 20 has a flexible, resilientouter wall 22 made of an air-tight material such as rubber, polymer, or rubberized fabric, that can be filled with air to form an inflatableouter chamber 25 within theflotation collar 20. For example, theouter chamber 25 can be inflated to a pressure of about 2 to 4 psig via aninflation valve 27. In the preferred embodiment shown in the drawings, the flotation collar contains a singleouter chamber 25 that surrounds theentire water craft 10. However, this could be subdivided by baffles or dividers into a plurality of outer chambers spaced around the periphery of thewater craft 10. Alternatively, a series of separate, discrete outer chambers can be spaced at intervals around thewater craft 10. This would enable each outer chamber to function independently for flotation purposes. - A plurality of
containment bags 30 are placed within theouter chamber 25 defined by theouter wall 22, as illustrated in FIG. 3. FIG. 4 is a top perspective view of acontainment bag 30. Eachcontainment bag 30 has an inner chamber filled, at least in part, with abuoyant material 35. FIG. 5 is a vertical cross-sectional view of theflotation collar 20 taken along lines 5-5 in FIG. 3 showing acontainment bag 30 filled withbuoyant material 35. For example, thebuoyant material 30 can be polymer foam, beads, or gas-filled balls. Thecontainment bags 30 are generally water-tight to help prevent thebuoyant material 35 from taking on water, and to help prevent degradation of thebuoyant material 35 due to long-term exposure to water. In the preferred embodiment of the present invention, thecontainment bags 30 are completely filled withbuoyant material 35. Alternatively, thecontainment bags 30 could be partially filled with buoyant material with the remainder of the inner chamber inflated with air. - In the embodiment shown in the drawings, the
containment bags 30 are arranged in a radial pattern within theouter wall 22 around the periphery of thewater park craft 10. Thecontainment bags 30 are preferably closely packed within theouter wall 22, similar to the segments of an orange, so that the side walls of eachcontainment bag 30 are adjacent to, or in contact with the side walls of the neighboring containment bags. Thecontainment bags 30 substantially fill theouter chamber 25 leaving a void adjacent to theouter wall 22. This helps to hold the containment bags in place within theouter wall 22, and also helps to define a desired overall shape for theflotation collar 20. Theouter wall 22 and the air-filled void between theouter wall 22 and thecontainment bags 30 serve as a bumper to help protect the foam from damages caused by impact with walls or other obstructions along the water park ride. However, other arrangements and configurations of thecontainment bags 30 could be readily substituted. - In the preferred embodiment of the present invention, each
containment bag 30 also has a fillingvalve 37 that extends through theouter wall 22 and into the inner chamber of thecontainment bag 30, as depicted in FIG. 6. The fillingvalve 37 is initially used to inflate thecontainment bag 30 within theouter chamber 25, as will be discussed below, and then to fill thecontainment bag 30 with thebuoyant material 35. The fillingvalve 37 also secures thecontainment bag 30 in position relative to theouter wall 22. - FIGS. 7 through 11 are cross-sectional views of the
flotation collar 20 illustrating the steps of inflating and filling the inner and outer chambers of theflotation collar 20. Thecontainment bags 30 are first inserted into theouter chamber 25 within theouter wall 22 of theflotation collar 20 in an uninflated state, as shown in FIG. 7. Thefill valves 37 serves to hold eachcontainment bag 30 in place. Eachcontainment bag 30 is then inflated via itsfill valve 37 as illustrated in FIG. 8. As previously discussed, inflation of all of thecontainment bags 30 brings them into contact with one another and substantially fills the entireouter chamber 25 as shown in FIG. 3. This helps to define the overall shape of theflotation collar 20 and ensures proper positioning of eachcontainment bag 30 within theouter chamber 25. Eachcontainment bag 30 is then filled via the fillingvalve 37 with thebuoyant material 35, as shown in FIGS. 9 and 10. Finally, theouter chamber 25 is inflated via itsinflation valve 27, as depicted in FIG. 11. Thecomplete flotation collar 20 can then be attached to thewater park craft 10 as shown in FIG. 1. - FIG. 12 is a cross-sectional view of an alternative embodiment of the
flotation collar 20. Thecontainment bag 30 is filled with abuoyant material 35 as before, but thecontainment bag 30 is not located within theouter chamber 25 as shown in the previous figures. Instead, thecontainment bags 30 are sandwiched between thewater park craft 10 and theouter chamber 25. Theouter wall 22 andouter chamber 25 continue to serve as a protective bumper for thecontainment bags 30. - The above disclosure sets forth a number of embodiments of the present invention. Other arrangements or embodiments, not precisely set forth, could be practiced under the teachings of the present invention and as set forth in the following claims.
