Floating craft stabilizing platform

Abstract

An accessory for addition onto a floating pontoon style fishing craft that enables the occupant to safely stand while the craft is floating without fear of tipping the craft. This is in the form of a lowerable, retractable platform that resides below the waterline of the craft and also incorporates a removeable working table/safety bar that resides in front of the occupant's seat to constrain them from falling overboard and to allow them a stable work surface from which to perform fishing related activities. The retractable platform serves to allow the center of gravity of the occupant to remain in close proximity to the waterline of the craft thus preventing tipping. Because of the depth the platform projects beneath the craft, the position of the occupant's mass acts as a stabilizer or ballast rudder so as to let the occupant to safely cast his fishing line from the craft.

Description

BACKGROUND OF THE INVENTION

The present invention relates to an extremely compact accessory for connection to a floating craft, targeted at personal floating pontoon fishing vessels, and adapted to provide both safety and convenience for the user. More particularly, to a system comprised of a retractable, lowerable platform and a table/safety bar restraint that can be retrofit onto a plethora of existing floating craft.

Personal, floating pontoon fishing vessels are quite popular with fishmen. One of the major drawbacks with these vessel is that the act of casting is limited for three reasons. First, when seated in the craft casting is accomplished forward of the occupant and the craft. There is no method for the occupant to pivot around in his seat to cast behind him. This is necessary as the craft rotates with the current as it moves down the river. Second, casting must be done from a seated position rather than the natural standing position. Lastly, the action of casting rocks the vessel making it somewhat unstable and dangerous.

Another drawback of these craft is that there is limited space and places from which to tie a fly, change a lure or work on a landed fish. While these type of craft are of great advantage for fisherman and offer improved features over shoreline or bank fishing, they are not able to reach their full potential for avid fishermen.

Henceforth, a retrofitable system for a pontoon float craft that would allow the occupant to cast in all directions safely coupled with a working platform would fulfill a long felt need in the fishing industry. This new invention utilizes and combines known and new technologies in a unique and novel configuration to overcome the aforementioned problems and accomplish this.

SUMMARY OF THE INVENTION

The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a lowerable, retractable platform that resides below the waterline of the craft and also incorporates a removeable working table/safety bar that resides in front of the occupant's seat to constrain them from falling overboard and to allow them a stable work surface from which to perform fishing related activities. The retractable platform (when stood upon) serves to allow the center of gravity of the occupant to remain in close proximity to the waterline of the craft thus preventing tipping. Because of the depth the platform projects beneath the craft, the position of the occupant's mass acts as a stabilizer or ballast rudder so as to let the occupant to safely cast his fishing line from the craft.

It has many of the advantages mentioned heretofore and many novel features that result in a new pontoon craft retrofittable system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art, either alone or in any combination thereof.

In accordance with the invention, an object of the present invention is to provide an improved lowerable, retractable fishing platform for a pontoon craft that (in combination with the occupant's weight) is capable of supporting the weight of a fisherman, and that acts as a below waterline ballast to stabilize the craft.

It is another object of this invention to provide an improved work surface capable that is capable of being retrofitted onto a plethora of existing pontoon craft via an adjustable attachment system.

It is a further object of this invention to provide a safety restraint device that can be affixed adjustably to a plethora of pontoon craft to ensure the occupant's safety when in the water.

DETAILED DESCRIPTION

The above description will enable any person skilled in the art to make and use this invention. It also sets forth the best modes for carrying out this invention. There are numerous variations and modifications thereof that will also remain readily apparent to others skilled in the art, now that the general principles of the present invention have been disclosed. There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.

As can best be seen in FIGS. 1, 2, 8 and 17 the floating craft stabilization platform 2 consists of a perforated, pivotable platform 4, an optional universal fit front mounting assembly 6, a platform lock assembly 8, a pair of adjustable fabric straps 10, an upper axle tube 12, a lower axle tube 13, an upper axle 15 a lower axle 17, a pair of adjustable, pivotable legs 14, a pair of lifting handles 16, a safety bar 36 and a table 74.

The stabilizing platform 2 is a retrofit accessory designed to attach to the various configurations of floating craft frames presently on the market. There are various floating craft manufacturers and there is a plethora of different frame designs that affix to and support the seat 18 and pontoons 40. The frame tubing used may be round, square or elliptical in cross section. The present design utilizes a pair of universal fit front mounting bracket assemblies 6 and an upper axle tube 12 that will accommodate the connection of the platform to the various configurations and dimensions of frame tubes. Since the platform is designed for use in salt, brackish or freshwater environments the components are rust and salt resistant by material and/or coating selection. In the preferred embodiment these are made of lightweight metal such as aluminum, although a UV resistant polymer would also be suitable as would be powder coated or stainless steel or galvanized metal.

The front mounting bracket assembly 6 (FIGS. 9-12) is made of an upper U shaped piece of channel 42 joined to a lower U shaped piece of channel 44. One side of the lower channel 44 is affixed to the bottom of the upper channel 42 such that their linear axes are parallel, but the open face of their U shapes are perpendicular. A strap connector 46 extends from the bottom of the upper channel 42. A set of U-bolts 48 are threadingly engaged with mating nuts 50 through orifices in the upper channel 42 so as to form two enclosed rings that allow the connection of the front mounting bracket assembly 6 to the floating craft frame members. It is to be noted that the strap connector 46 may be utilized as a connection point for the straps 10 or not, as the straps may directly encircle the frame or may be situated so as to directly encircle the front mounting bracket assembly 6 when mounted on the frame.

It is known that in an alternate embodiment the front mounting bracket assembly 6 may be eliminated completely. This would be done when the user has no need for a safety bracket 36. In this configuration the straps 10 have their top end looped around the frame of the floating craft rather than around the front mounting bracket assembly 6 or around the strap connector 46 on the front mounting bracket assembly 6. In all other aspects the straps 10 would function identically.

The straps 10 are of a flexible fabric adapted for use in water that have their proximate ends looped through the strap connector 46 (or encircling the frame) and then enmeshed with an adjustment buckle 20 located on the straps between the distil and proximate ends. The perforated platform 4 is a generally rectangular, planar member with numerous perforations 5 formed there through to allow water to freely pass. (FIGS. 13-16) Affixed to the front edge of the platform 4 is a pair of platform strap loops 7 through which the distil end of the strap 10 is attached. In another embodiment of connection, the two ends of the adjustable strap may just be joined at the buckle 20. In either configuration, the front of the platform 4 may be raised or lowered by adjusting the amount of strap 10 that passes through the buckle 20.

Looking at FIGS. 7 and 8 it can be seen that under the seat, affixed to the pontoon boat's frame crossmember (shown in phantom) is the upper axle tube 12. This tube may be welded or mechanically affixed to the crossmember by bolts or clamps. In the preferred embodiment there is a section of flat bar 21 affixed to the upper axle tube 12 and that serves as the point of connection between the upper axle tube 12 and the crossmember by welding. On the upper axle tube 12 extends a locking lever assembly made of a locking lever arm 24 that pivots about pivot pin 25 which is affixed to locking lever bracket 22. The locking lever arm has a leg portion 28 that will extend through a slot cut in the upper axle tube 12 so as to reside within one of the alignable locking slots 32 cut in the upper axle 30. When the handle portion of the locking lever arm 24 is raised the leg portion 28 will disengage from the upper axle 30 allowing the upper axle 30 to freely pivot within the upper axle tube 12 and raise or lower the two legs 14.

The platform 4 is of a generally planar configuration with a series of perforations 5 formed therethrough. At the front of the platform 4 is a pair of strap loops 7 that extend to allow passage of the strap 10 which suspends the front end of the platform 4. The rear of the platform is pivotally attached to the legs 14 by the lower axle tube 13, the lower axle 17 as described herein.

The leg 14 is comprised of an inner leg member 36 which slidingly resides within outer leg member 38 so as to enable a telescopic style adjustment of leg 14. There are a set of matchingly dimensioned locking pin orifices 60 formed through both the outer leg member 38 and the inner leg member 36 so as to accommodate locking pin 23 to affix the length of the leg 14. Attached to the outer leg member 38 is a top guide 27 which keeps the handle 16 and the leg 14 parallel and adjacent at all times. An optional stabilizing brace 99 is affixed between inner leg members 36. At the bottom of the inner leg members 36 are orifices that accept either end of a lower axle 17 for pivotal motion. The lower end of the inner leg members 36 resides within lower leg brackets comprised of an outer plate 62 and an inner plate 64 which reside parallel to each other and extend normally from the rear edge of platform 4. The lower axle tube 13 is affixed at either end to one of the inner plates 64 and rotationally houses lower axle 17 which passes through an orifice in the inner plate (not visible) and an orifice in the outer plate 62. There is also an optional support 98 that may be used to affix the midpoint of the lower axle tube 13 to the platform's rear edge. The lower axle may be retained therein by a number of mechanical means including mushrooming the axle ends, pins, bolting arrangements, devises, and the like. This design enables pivoting movement of the platform 4 with respect to the legs 14 as the platform 4 is raised or lowered. There is a series of matingly sized orifices formed through the inner leg member 36 and the outer leg member 38 that align at different extensions so as to receive an adjustment pin 29 to lock the leg 14 at the desired length.

The handle 16 is a linear member having a bottom guide 54 affixed thereto that is slidingly attached to the leg 14 by inserting the handle 16 first through the top guide 26 then sliding the inner leg member 36 (deattached) through the bottom guide 54 of the handle, then assembling the outer and inner leg members. There are many embodiments of a handle possible as the handle 16 is but a lifting mechanism. It need not be rigidly or slidingly affixed to the leg 14, rather it could be a cable or stay arrangement that serves simply as a mechanism to lift the leg 14.

Attachment of the stabilizing platform 2 requires the user to affix the front mounting bracket assemblies 6 to the tubular frame of the craft with the U bolts and mechanically affixing the upper axle tube 12 to the crossmember. Looking at FIGS. 3-6 in conjunction with FIGS. 7 and 8, the operation of the platform 2 can best be illustrated. The platform 4 resides in the water below and in front of the floating craft's seat 18. The actual depth of the platform 4 is determined by adjustments of the buckles 20 on the straps 10 and the telescopic extension or retraction of the inner leg member 36 from within outer leg member 38. There is a series of matingly sized orifices formed through the inner leg member 36 and the outer leg member 38 that align at different extensions so as to receive an adjustment pin 29 to lock the leg 14 at the desired length. When adjusted properly, this results in a generally horizontal platform orientation. (FIG. 3) The handles 16 are raised vertically and are constrained adjacent and parallel to the legs 14 by handle mounted bottom guides 54 and outer leg member mounted top guide 27. (FIG. 4) The handle portion of the locking lever arm 24 is raised so that the leg portion 28 will disengage from the upper axle 30 and allow upper axle 30 to freely pivot within the upper axle tube 12 and raise or lower the two legs 14 when the handles 16 are pushed forward and down (toward the waterline at the bow of the craft). This action will cause the legs 14 and platform 4 to pivot up and back (FIG. 8) toward the stern of the craft. Because the platform 4 is pivotally affixed to the legs 14 by a lower axle assembly, as the legs 14 are pivoted rearward the platform remains in a horizontal position by the tension between the straps 10 and the strap loops 96 on the front of the platform 4. When the platform 4 reaches the fully raised position such that it tucks in underneath the seat 18 the handle portion of the locking lever arm 24 is lowered so that the leg portion 28 will engage the slots in the upper axle 30 to lock the upper axle 30 within the upper axle tube 12 and hold the legs 14 and platform 4 in the retracted position. (FIG. 5) The handles 16 are then slid backward and out of the way. With the use of the straps 10 to secure the front of the platform 4 there are no hard obstacles for the user to bump his legs on when the platform 4 is in the retracted position.

Depth adjustment of the platform 4 is set to accommodate the leg length of the user such that they can easily return to a seated position and that the safety bar 36 (FIG. 17) is between the knee and waist of the user.

When the platform 4 is lowered the user may stand on it to cast his line in any direction. This stabilizes the craft as the user and platform assembly combined, now function as a ballast to keep the craft from tipping as the user turns to cast in different directions. It also allows functions as a rudder to keep the craft moving in line with the current in a river, creek or stream rather than moving directionally with the surface wind. In the case of lake usage, it prevents the craft from blowing about.

The platform 4 and legs 12 whether retracted or extended serve as a ballast to help stabilize the floating craft. Although not having a substantial mass, the perforated design of the platform 4 allows it to offer extreme resistance to movement of the attached craft by virtue of the resistance it offers to water flowing through the perforations as the craft attempts to pivot or move. This feature greatly enhances the stability and safety of the craft.

Between the front mounting bracket assemblies 6 may be a safety bar 36 which is pivotally and removeably affixed to the front bracket assembly 6. This pivot connection and the lock on the other end of the safety bar 36 are well known in the art and are not illustrated. This safety bar serves to stabilize the frame and to prevent the user from falling forward out of the craft while standing on the platform 4. On distal end of the safety bar 36 is a table pedestal support 70 that slidingly engages the pedestal 72 of the table 74. This support is section of tubing with its inside dimensions larger than the outside dimensions of the similarly configured tubing of the table pedestal 72. A wingbolt (not visible) engages a threaded recess in the table pedestal support 70 so as to frictionally engage the pedestal 72 within the table pedestal support 70 and set the height of the table 74.

Although depicted with two handles 16 as the raising/lowering mechanism in an alternate embodiment only one handle would be utilized. In this configuration the other remaining components would remain identical, thereby allowing the user to select on which side he would prefer the handle 16 to be placed. There are other affixing arrangements such as bolting or compression clamping that would be suitable to attach the front mounting assembly 6 to the frame of the craft, (as would be well known in the art) however the one chosen for this device accomplishes the best overall adaptation for connection to the various frame design. Similarly, physical changes to the U shaped configuration of the mounting assemblies are well within the scope of the disclosure above.
