FIELD OF INVENTION
The present invention relates to an improved simple design for a water propelled flying board, wherein the basic design is described in U.S. patent application Ser. No. 14/066,997 issued as U.S. Pat. No. 9,145,206 on Sep. 29, 2015) and provisional application nos. 62/018,268 and 62/121,073, all of which are incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTION
The above referenced patent applications describe a flying board wherein the left and the right lift nozzles can be independently rotated forward and backward relative to the central Y housing that receives the high pressure water (from a jet ski). No prior art features of a spring return of the left and right platform segments or a locking of these segments exists.
SUMMARY OF THE INVENTION
The present design uses a new and twistable rubber hose or a bushing assembly that is easily replaced after wear and tear. There is also disclosed a least expensive method of plastic manufacturing to provide a complete system. Some parts are roto molded (rotational molding). Metal screws and bolts thread into brass inserts for all couplings.
A newly available competitor's model uses an expensive pair of watertight bearings to allow the powered nozzles to rotate. The present invention replaces those bearings with bendable rubber hoses. This greatly reduces the product cost and reduces maintenance issues with bearing replacements as sand always exists in the water. Thus, any bearing in a system like this will eventually wear out.
The present invention does have one main inlet bearing. But the two foot platforms, one on each arm of the Y tube, now rotate using a new, useful hose segment.
The present invention provides a spring return of the left and right platform segments and a locking of these segments.
The main aspect of the present invention is to provide water propelled flying board that has an independently rotatable nozzle under the left and the right foot platform with a spring return to a neutral position.
Another aspect of the present invention is to manually lock or unlock the foot platforms.
Another aspect of the present invention is to provide a low cost rubber hose bearing which is easily replaced to take the majority of the wear and tear of the rotational friction of the foot platforms under power.
Another aspect of the present invention is to use some roto molded parts with metal connectors.
Another aspect of the present invention is to provide a custom built hose to enable both a twisting and a bending motion.
Other aspects of this invention will appear from the following description and appended claims, reference being made to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

DETAILED DESCRIPTION OF THE DRAWINGS
Referring first to FIGS. 1, 2 the jet ski JS floats on the water WA and powers the hose 2. In FIG. 1 the rider R has his left foot toe up TU and his right foot toe down TD. Thus, water thrust 1600 could force his left shoulder back while water thrust 1601 could force his right shoulder forward. The rider R spins in a counter clockwise CC pattern. The rider R depicted in dots RD shows him rotationally three fourths through his full 360° rotation while travelling up U.
In FIG. 2 the rider R starts high above the water WA. Then rider R dives down D while spinning counter clockwise CC as shown by rider RD. Then rider R surfaces S and proceeds horizontally as shown by rider RH. All this time he is rotating counter clockwise CC. He could reverse his rotation by changing his toe up/down positions.
In FIG. 3 the Y pipe hose 348 can be made completely from silicone and fiber or other synthetic rubber.
FIG. 6 shows how crisscrossed elastic bands 1300 (attaches at 501, 500), 1301 (attaches at 500, 501) urge the left and right foot platforms L401, R401 to be parallel. Thus, the rider must push harder and harder as he increases the angular opposition between the left and the right platforms. This feature also protects the rider from injury. The elastic bands 1300, 1301, could be mounted parallel. The tension bands can be replaced by elastic metal springs.
Referring next to FIGS. 3, 4 a flying board 100 has a left foot platform L401 which can bend and twist independently from a right foot platform R401. A lock assembly 4 can be attached to the platform or the center blocks, and it allows the rider to lock the left and right foot platforms together or the left and right center blocks 311A and 311B together. A stabilizing assembly 300 keeps the nozzles 320, 321 from flaring in or out or sideways, and it allows the nozzles to move 360 degrees. The center blocks 311A, 311B are supported by the Y pipe assembly 330 and are able to rotate. The (metal) arms 303, 304, 305, 306 attach to the foot platforms via bolts (not shown) and anchors 307, 308, 309, 310 respectively. Design choice could add more or less arms. Brackets 322 attach to the respective foot platforms.
The Y pipe assembly 330 comprises a (plastic or metal) stiff central base built into the silicone hose 331. The left branch comprises a hose segment 334 connected to the port 332. The Y pipe hose 348 can be a one piece silicone hose or it can be made from other synthetic rubber. The hose can have metal or plastic parts built into it. The arrows B show how hose segment 334 can bend. The arms of the Y pipe hose are one piece 335,334, 333 and 332, and they can twist or bend. Hollow arrows T show how hose segment 334 can twist. Hose segment 335 bends downward to support the nozzle 320. Clamps 337 with bolts 338 form clasp 400 and secure the hose segment 334 to the respective foot platform.
A hose segment 340 attaches to the bottom port 339 of the central base 331. This hose segment 340 can bend 180 degrees as shown in FIGS. 4, 5B. It can be about six inches long or longer. This bending allows the rider R to do back flips or move forward or backward or sideways.
A threaded mender 343 connects the base of the Y pipe hose 340 to top 342, and the other end of the mender 345 connects to the fire hose 2. The mender section 344 can spin 360 degrees. A spinning type bearing (can be made with or without ball bearings) 344 allows lower threaded pipe 345 to spin relative to top 342. Support rods or cables 350, 351, can be stainless steel. They attach the respective boot platform to the collars 346, 343, thereby taking the (250 pound) weight of the hose 2 off the Y pipe assembly 330. FIG. 5A shows the rider R going straight up with hose segment 340 straight. FIG. 5A shows the rider R going straight down with hose segment 340 bent 180 degrees.
The hoses are made preferably of silicone rubber and polyester plain woven, used as a reinforcement ply. Other choices of synthetic rubber are equivalents.
FIG. 7 shows hose segment 348 with a silicone rubber body RB reinforced by polyester plain woven fibers PPW.
Nominal thickness T ranges from 0.10 inches to 0.50 inches.
Referring next to FIG. 8 a plastic bearing flying board is numbered 800. The parts are described below. The boards 400 and 800 perform the same.
The flying board 400 of FIG. 1 has a left foot platform L401 and a right foot platform R401.

- Rotational Molding (BrE molding also called roto molded) involves a heated hollow mold which is filled with a charge or shot weight of material. It is then slowly rotated (usually around two perpendicular axes) causing the softened material to disperse and stick to the walls of the mold. In order to maintain even thickness throughout the part, the mold continues to rotate at all times during the heating phase and to avoid sagging or deformation also during the cooling phase. The process was applied to plastics in the 1940s but in the early years was little used because it was a slow process restricted to a small number of plastics. Over the past two decades, improvements in process control and developments with plastic powders have resulted in a significant increase in usage.
Although the present invention has been described with reference to the disclosed embodiments, numerous modifications and variations can be made and still the result will come within the scope of the invention. No limitation with respect to the specific embodiments disclosed herein is intended or should be inferred. Each apparatus embodiment described herein has numerous equivalents.
