Floating Wading Aid
A floating wading aid provides stability and support to a wader walking between pontoons at about the center of buoyancy of those pontoons, with suitable frame structure provided. The pontoons may be fillable with air or floating objects, and a movable platform may be provided.
This invention is a floating device intended to aid a wader in maintaining stability and balance while wading, especially in areas with uneven or muddy bottoms. The floating wading aid also provides a means of transporting gear and other items while wading. In particular, the floating wading aid makes it much easier for a person wading to lift his or her feet out of the mud while applying downward force to the handles of the floating wading aid. Prior art floatation devices include a U-shaped rigid pontoon (see U.S. Pat. No. 8,292,683 to Axtell) and configurations that fully enclose a wader within a rigid structure (see U.S. Pat. No. 6,843,695 to Jackson). Prior art double pontoon boats exist for use by a person sitting in a seat anchored well above the pontoons using oars to maneuver the boat and are not designed for use by a wader. No prior art devices provide the usability and portability of this invention.
This floating wading aid: (1) is easily maneuverable by a person wading between the pontoons or within the U-shaped pontoon while grasping the wading aid (using handles on the pontoons or frame) at about the “center of buoyancy” of the pontoons (the “wading position”); (2) permits a wader to enter into the wading position without climbing over portions of the pontoons or framing; and (3) is convenient to transport and store. Other desirable features would include a platform to hold items being transported and/or a seat that would be located at approximately the center of buoyancy but could be moved forward to allow a person to wade in the wading position without obstruction, with the seat allowing a user to sit with a low profile with his or her weight supported in whole or in part by the pontoons. Particularly in a hunting situation, it is desirable that the user's profile remains as low as possible and the position of the platform as a seat should be as low as possible, at or slightly above or below water level.
SUMMARY OF THE INVENTIONThis floating wading aid includes one or more flotation units (referred to as pontoons). A preferred configuration of the invention is referred to as a double pontoon configuration, with two pontoons parallel to each other. Another configuration is a single U-shaped pontoon. The wader would either walk between the double pontoons or within the U-shaped pontoon with the floating wading aid providing significantly improved stability.
For purposes of this invention the pontoons have a center of buoyancy (sometimes called a center of floatation) measured front to back at the location marked as C/B in
In a preferred embodiment of this invention the pontoons to not have fixed rigidity but in one state are flexible and capable of being enlarged to a more rigid shape that will effectively displace water. For purposes of this description, this type of flexible structure is referred to as a “fillable sleeve.” In one embodiment the fillable sleeve is an inflatable pontoon that, when filled with air, provides a suitable shape for displacing water. In another embodiment the fillable sleeve includes pockets or divided spaces that may be filled with more rigid floating objects to create the rigidity to provide suitable water displacement. In many duck hunting situations, the wader is likely to be transporting duck decoys and those decoys would constitute suitable rigid floating objects for placement in the fillable sleeve to provide rigidity and water displacement capability. The fillable sleeve may be made of canvas, nylon, or another fabric or other flexible and water resistant material and may include a separate inflatable rubber bladder. For convenience, a reference to “fillable sleeve” refers to both the sleeve and any inner bladder, if applicable. The fillable sleeve pontoons, whether air inflatable or configured to be filled with objects like duck decoys, make this floating wading aid easy to transport and store.
This invention comprises pontoons—either two pontoons 2, 4 as shown in
A platform 10 may be provided that in at least one position is forward of the center of buoyancy and is supported either directly by the pontoons or by portions of the frame (and in in turn supported by the pontoons). As shown in
As shown in
In operation, a wader would rotate the platform to the forward position as shown in

Other pontoon configurations could be utilized, such as a four pontoon configuration with two sets of two pontoons, all parallel to each other. The single U-shaped pontoon could be replaced with three pontoons, or 2 pontoons could be used in a V configuration. The location of the frame on the pontoons could be adjusted to accommodate a situation where a significant load (like a dog's weight) is expected on the second platform, so that the weight distribution across the pontoons would cause the pontoons to be level (front to back).
Claims
1. A floating wading aid comprising two pontoons each having a forward end, a rearward end, and a center of buoyancy between said ends and a frame attachable to the pontoons maintaining the spacing of the pontoons but not interfering with the movement of a wader between the pontoons at said center of buoyancy.
2. The floating wading aid of claim 1 wherein said pontoons are fillable sleeves.
3. The floating wading aid of claim 2 wherein said fillable sleeve pontoons are configured to contain multiple floating decoys.
4. The floating wading aid of claim 2 wherein said fillable sleeve pontoons are configured to be filled with air.
5. The floating wading aid of claim 1 further comprising a platform extending between said pontoons and in one position forward of the center of buoyancy.
6. The floating wading aid of claim 3 further comprising support straps on the bottom of said pontoons for receiving portions of said frame.
7. The floating wading aid of claim 5 with said platform rotatable from said position forward of the center of buoyancy to a position substantially at said center of buoyancy.
8. The floating wading aid of claim 1 further comprising handles on said pontoons substantially at said center of buoyancy.
9. The floating wading aid of claim 1 further comprising frame portions substantially at said center of buoyancy serving as handles.
10. The floating wading aid of claim 7 further comprising a second platform in a fixed position forward of said center of buoyancy.
11. A floating wading aid comprising a U-shaped pontoon comprising a fillable sleeve and having a forward end at the front portion of the U-shaped pontoon, a rearward end, and a center of buoyancy between said ends and a frame attachable to the pontoon not interfering with the movement of a wader at said center of buoyancy.
