FIELD OF THE INVENTION

The present invention pertains to water sports. More particularly, the present invention relates to a Method and Apparatus for Insta Fill Wake System.

BACKGROUND OF THE INVENTION

In several water sports, for example, but not limited to, wakeboarding, waterskiing, etc., â€œgetting airâ€ is desirable. One way of â€œgetting airâ€ is to launch oneself off a wave in the water into the air. This wave can be created by a boat, for example, towing person(s) engaging in the water sport. This wave created by the boat is often referred to as a wake. To create a wake a boat must displace water as it moves forward. One approach to displace as much water as possible is to lower a boat in the water. This lowering can be achieved by placing ballast tank(s) in the boat. However filling and emptying the ballast tanks(s) is slow and can involve pumps, valves, plumbing, etc. Additionally valves and plumbing may leak resulting in a boat sinking. This presents a technical problem for which a technical solution using a technical means is needed.

In one embodiment of the invention, the system uses a single gate per ballast tank for both filling and emptying while a boat is in motion.

In one embodiment of the invention, the system uses a single gate per ballast tank without any pumps or scupper for both filling and emptying while a boat is in motion.

In one embodiment of the invention, the system uses a single gate with a scupper per ballast tank without any pumps for both filling and emptying while a boat is in motion.

In one embodiment of the invention, the system does not use pumps to fill some ballast tank(s).

In one embodiment of the invention, the system uses only a gate for controlling filling/emptying of some of the ballast tank(s).

In one embodiment of the invention, the system operates with no valves to control filling/emptying of some of the ballast tank(s).

In one embodiment of the invention, the system uses water pressure on a gate to fill ballast tank(s).

In one embodiment of the invention, the system works using water pressure developed while the boat is in forward motion to fill/empty ballast tank(s).

In one embodiment of the invention, an air venting system for ballast tank(s) are used.

In one embodiment of the invention, the system without using anything further solely uses the boat's forward motion to empty ballast tank(s).

In one embodiment of the invention, the system using a gate and the boat's forward motion can empty ballast tank(s).

In one embodiment of the invention, the system uses gate(s) mounted on the transom of a boat.

In one embodiment of the invention, the system uses gate(s) mounted on the ballast tank(s) of a boat.

In one embodiment of the invention, the system uses U-shaped ballast tank(s) and one or more gates on the ends of the U-shaped ballast tank(s).

In one embodiment of the invention, the system uses gate(s) mounted on the ballast tank(s) of a boat located between bow and stern.

In one embodiment of the invention, the system uses air vent(s) on the ballast tank(s) to control filling/emptying rate.

In one embodiment of the invention, the system uses air vent(s) on the ballast tank(s) and located above the ballast tank and between the front and rear of the ballast tank(s).

In one embodiment of the invention, the system uses deployable water pick-ups that are mounted on a gate.

In one embodiment of the invention, the system uses deployable water pick-ups that are mounted on a gate and the water pick-ups may be raised to eliminate drag on the boat as it is moving.

In one embodiment of the invention, the system uses deployable water pick-ups that are mounted on a gate, and the gate is mounted on a boat transom.

In one embodiment of the invention, the system uses deployable water pick-ups that are deployed on a gate.

In one embodiment of the invention, the system uses deployable water pick-ups that are deployed past the boat transom on a gate.

In one embodiment of the invention, using the gate force feed water allows the ballast tank(s) to be taller than the waterline and thus being able to fill ballast tank(s) above the waterline thereby adding more water which increases the weight on the boat which results in a bigger wake.

In one embodiment of the invention, using the gate force feed water creates pressure without the use of pumps, diversion valves, check valves, etc.

In one embodiment of the invention, the ballast tank(s) run all the way to the transom of the boat.

In one embodiment of the invention, the gate can hinge up and down from the transom of the boat.

In one embodiment of the invention, a sliding gate flush mounts to the inboard or outboard side of the transom. The gate can slide vertical up and down.

In one embodiment of the invention, the system integrates both the intake and the outlet, reducing both filling and emptying times and reducing moving parts by running the ballast tanks through the transom of the boat and using a gate.

In one embodiment of the invention, opening the gate will expose approximately 90% of the rear end of the ballast tank. This will instantly flood the ballast tank assuming the air vents allow for adequate air venting.

In one embodiment of the invention, ballast tank(s) running all the way to the transom of the boat where an opening is located for water entry/exit prevents a leaking seal on the transom from flooding the boat because only the ballast tank(s) with a leaking seal will fill with water, not the boat.

In one embodiment of the invention a gate can hinge up and down from the transom of the boat. In one embodiment a sliding gate that flush mounts to the inboard or outboard side of the transom can be used that can slide vertically up and down.

In one embodiment of the invention both the intake and outlet are integrated into a single multi-positionable gate such that both filling and emptying times are reduced, and moving parts are reduced compared to using pumps, valves, etc.

In one embodiment of the invention both the intake and outlet are integrated into a single opening, reducing both filling and emptying times and reducing parts by running the ballast tanks through the transom of the boat and using a gate.

In one embodiment of the invention opening the gate will expose approximately 90% of the rear end of the ballast tank. This will instantly flood the ballast tank as long as the air vents allow for adequate air venting.

In one embodiment of the invention, since filling/emptying can be done when the boat is on plane, less horsepower is needed and less fuel is consumed compared to starting a boat from standstill with full ballast tank(s).

In one embodiment of the invention, the system will allow the tanks to empty while picking up a fallen or downed rider. The process used to pick up a downed rider with full ballast tanks is:

- 1. When the skier falls, open the water gate (FIG. 1 at 104). This lets the ballast tank (FIG. 1 at 106) water out of the tanks.
- 2. Close the water gate (FIG. 3 at 305) so the boat does not refill when the boat stops.
- 3. Pick up rider.
- 4. Deploy the scupper (from position FIG. 1 at 103 to position FIG. 2 at 203).
- 5. As the boat starts, open the water gate (FIG. 2 at 204) to fill the ballast tanks. The tanks will fill in approximately 5 seconds.
- 6. When the tanks are full, retract the scupper (FIG. 1 at 103) and close the water gate (FIG. 3 at 305).

In one embodiment of the invention this approach eliminates the need for massive horse power in boats or the need for a transmission to plane the boat with large amounts of water in it saving a considerable amount of money in fuel, big engines and transmissions to carry water.

In one embodiment of the invention, the air vent (for example, FIG. 4 at 408) may be throttled to control the intake and release of water from the ballast tanks.

In one embodiment of the invention The water intake gate (for example, in FIG. 5 at 504) may be operated by a variety of different methods, for example, but not limited to hydraulic, pneumatic, electrical, mechanically, etc.

In one embodiment of the invention, this system uses a stationary water pick up (water dam) (for example, FIG. 1 at 105) combined with a deployable water scupper (for example, FIG. 1 at 103) used in combination this will turn the water gate (for example, FIG. 1 at 104) into a water scoop which will make it possible to fill and empty tanks through the same hole.

In the USA right now there is a huge problem of transporting mussels from lake to lake. Most lakes in the western US require an inspection of the boat to eliminate the migration of mussels between lakes. The old systems have no way to inspect for mussels in the enclosed tank. In one embodiment of the invention, this new system would allow for inspection by opening up the rear end of the tank (e.g. opening the gate).

In one embodiment of the invention a gate (for example, FIG. 1 at 104) is used combined with a deployable water scupper (for example, FIG. 1 at 103) and water dam(s) (for example, FIG. 1 at 105) to make it possible to fill and empty tanks through the same hole.

FIG. 1 illustrates, generally at 100, one embodiment of the invention showing a side view filling stationary position with scupper retracted. 101 is a support housing bracket. 102 is a gate deployment cylinder. 103 is a deployable scupper (shown here in the up position). 104 is a water intake gate (shown here in the open position). 105 is a stationary water dam (port). 106 is a ballast tank. 107 is a scupper deployment cable. 108 is a boat. At 109 is a transom of boat 108. At 110 is a waterline indication for a full ballast tank 106. At 111 is a waterline indication for an empty ballast tank 106.

As shown in FIG. 1, the ballast tank 106 extends all the way to the transom 109. In this embodiment if there is a leak in the water intake gate 104 to transom seal when the water intake gate is closed the boat 108 will not be flooded. That is without forming a seal between the water intake gate 104 and the transom 109 the boat 108 will not flood. The worst that happens is the ballast tank 106 slowly fills or empties.

As shown in FIG. 1, the ballast tank 106 extends all the way to the transom and the water intake gate in the open position allows for easy visual inspection of the ballast tank 106. In this way foreign matter (e.g. marine life, etc.) may be inspected for in the ballast tank 106. That is a human may place their eyes between the stationary water dam 105 (only one shownâ€”one on each side of water intake gate 104) and the water intake gate 104 peering into the ballast tank 106.

In one embodiment of the invention, for example, as partially illustrated in FIG. 1, the deployable scupper 103 and the scupper deployment cable 107 are not needed. That is a gate, for example, as illustrated at FIG. 1 at water intake gate 104, without a scupper, for example, as illustrated at FIG. 1 at deployable scupper 103, may be used to fill and empty a ballast tank, for example, as illustrated at FIG. 1 at ballast tank 106.

In one embodiment of the invention, for example, as illustrated in FIG. 1 at gate deployment cylinder 102 the gate deployment cylinder may be any mechanical means to operate the gate. For example, gate deployment cylinder may be, but is not limited to, a cable assembly, a gear assembly, a pneumatic assembly, a hydraulic assembly, a ball screw assembly, etc. Additionally, the position of the gate deployment cylinder, for example, as shown in FIG. 1 at gate deployment cylinder 102, may be outboard the boat 108 as shown or inside the boat 108. Additionally, the gate deployment cylinder 102 may be powered by a variety of means, for example, but not limited to, user cranked, electric, compressed fluid, compressed gas, mechanically linked to a boat 108 motor, etc.

While the ballast tank 106 is shown going to the transom 109 in FIG. 1, the invention is not so limited, and the ballast end may be placed forward of the transom with the gate also moved forward of the transom. In one embodiment of the invention, the gate is located on the rear of the ballast tank.

In one embodiment of the invention, without a deployable scupper, the gate may be used to fill and drain through the same hole in a ballast tank while the boat is moving through the water.

In one embodiment of the invention, without a deployable scupper, the gate may be used to fill a ballast tank while the boat is not moving through the water.

In one embodiment of the invention, without a deployable scupper, the gate may opened for example at a 10 degree angle to being fully closed to fill a ballast tank while the boat is moving through the water. In one embodiment of the invention the gate may be opened between 2 degrees and 90 degrees relative to being fully closed to fill a ballast tank while the boat is moving. In one embodiment of the invention the gate may be opened between 11 degrees and 135 degrees relative to being fully closed to empty a ballast tank while the boat is moving.

In one embodiment of the invention, without a deployable scupper, the gate may be opened 10 degrees with respect to a normal to the waterline for rapid filling.

FIG. 2 illustrates, generally at 200, one embodiment of the invention showing a side view filling running position with scupper deployed. 201 is a support housing bracket. 202 is a gate deployment cylinder. 203 is a deployable scupper (shown here in the down position). 204 is a water intake gate (shown here in the open position). 205 is a stationary water dam (port). 206 is a ballast tank. 207 is a scupper deployment cable. 208 is a boat. At 209 is a transom of boat 208.

FIG. 3 illustrates, generally at 300, one embodiment of the invention showing a side view water intake gate closed. 301 is a support housing bracket. 302 is a gate deployment cylinder. 303 is a deployable scupper (shown here in the up position). 304 is a stationary water dam (port). 305 is a water intake gate (shown here in the closed position). 306 is a ballast tank. 307 is a scupper deployment cable. 308 is a boat. At 309 is a transom of boat 308.

FIG. 4 illustrates, generally at 400, one embodiment of the invention showing a side view. 401 is a support housing bracket. 402 is a gate deployment cylinder. 403 is a deployable scupper (shown here in the down position). 404 is a water intake gate (shown here in the open position). 405 is a stationary water dam (port). 406 is a ballast tank. 407 is a scupper deployment cable. 408 is an air vent. 410 is a floor board.

In one embodiment of the invention, for example, as illustrated in FIG. 4, there are a plurality of air vents, like that illustrated in FIG. 4 at 408, and the vents may be located forward on the ballast tank(s). In one embodiment of the invention air vent opening(s) may be rectangular in shape.

In one embodiment of the invention, the system uses valves (not shown in FIG. 4) on the air vent(s), for example, as illustrated in FIG. 4 at 408 to control the amount of air that enters/exits the air vent thereby controlling the filling/emptying rate of the ballast tank(s).

FIG. 5 illustrates, generally at 500, one embodiment of the invention showing a rear view. Note that a gate is not depicted on the starboard side. 501 is a support housing bracket (port). 502 shows two gate deployment cylinders (port). 504 is a water intake gate (shown here in the closed position). 505 is a stationary water dam (port). 506 is a ballast tank (port). 507 is a ballast tank (starboard).

While FIG. 5 illustrates two gate deployment cylinders, the invention is not so limited and one gate deployment cylinder may be used, or more than two may be used.

FIG. 6 illustrates, generally at 600, one embodiment of the invention showing a side view where the ballast tank 602 is located forward of the transom 604 and the gate 606 is used to open/close with an opening on the rear of the ballast tank 602.

In one embodiment of the invention, without a deployable scupper, the gate may be opened 10 degrees with respect to a normal to the waterline for rapid filling. For example in FIG. 6 assume the bottom of the ballast tank 602 is parallel to the waterline, then 608 is 10 degrees.

FIG. 7 illustrates, generally at 700, one embodiment of the invention showing a top view of a boat 702 having a transom 704 and two U-shaped ballast tanks 706 and 708. In this embodiment the transom 704 has a plurality of openings 710, 712, 714, and 716. Openings 710, 712, 714, and 716 may be used to fill/empty the respective ballast tanks 706 and 708. Not shown on these opening are the gates that can open/close the openings 710, 712, 714, and 716. Various operations of the gates that open/close the openings 710, 712, 714, and 716 allow for filling and emptying. For example, the gates for 712 and 716 may be opened to fill the ballast tanks 706 and 708. Not shown in FIG. 7 are ballast tank air vents that allow the air in the ballast tanks to be replaced by water when filling and water to be replaced by air when the ballast tanks are emptying. If ballast tanks 706 and 708 are to be quickly filled/emptied gates for 710, 712, 714, and 716 may be opened for filling/emptying. Gates 710, 712, 714, and 716 may be operated independently to achieve different boat performance. For example, assume ballast tanks 706 and 708 are empty and it's desired to lower the port side. Gates for one or more of 714 and 716 may be opened while gates for 710 and 712 remain closed. One of skill in the art will appreciate that all manner of possible opening for filling and emptying the ballast tanks, and closing for retaining water in the ballast tanks are possible.

FIG. 8 illustrates, generally at 800, one embodiment of the invention showing a side view of a boat 810 with a three position pivoting track shown in the closed position. At 809 is a transom. At 801 is a gate, at 802 is an actuator, at 803 a bracket, at 804 a side dam, at 805 a ballast tank, at 806 a vent, at 807 two gate positioning tracks, and at 808 two gate positioning bolts. At 820 is an expanded external view of the bracket 803, the side dam 804, the gate positioning tracks 807, and the gate positioning bolts 808. The expanded view 820 shows a three position pivoting track mechanism shown in the closed position.

FIG. 9 consists of FIG. 9A and FIG. 9B.

FIG. 9A illustrates, generally at 900, one embodiment of the invention showing a side view of a boat 910 where a three position pivoting track mechanism expanded external view 920 is shown in a flood position for filling ballast tank 905. At 901 is a gate, at 902 an actuator, at 903 a bracket, at 904 a side dam, at 905 a ballast tank, at 907 two gate positioning tracks, and at 908 two gate positioning bolts. At 920 is an expanded external view of the gate positioning track 907, and the gate positioning bolt 908. The expanded view 920 shows a three position pivoting track mechanism shown in the flood position. As illustrated in FIG. 9A the gate is in intimate contact with the ballast tank 905. If the ballast tank 905 is mounted against a transom such as 909 then the gate 901 is in intimate contact with the opening in the transom 909.

FIG. 9B illustrates, generally at 930, one embodiment of the invention showing a side view of a boat 940 where a three position pivoting track mechanism expanded external view 950 is shown in a drain position for draining ballast tank 935. At 931 is a gate, at 932 is an actuator, at 933 a bracket, at 934 a side dam, at 935 a ballast tank, at 937 two gate positioning tracks, and at 938 two gate positioning bolts. At 950 is an expanded external view of the gate positioning tracks 937, and the gate positioning bolts 938. The expanded view 950 shows a three position pivoting track mechanism shown in the drain position. As illustrated in FIG. 9B the gate is in intimate contact with the ballast tank 935. If the ballast tank 935 is mounted against a transom such as 939 then the gate 931 is in intimate contact with the opening in the transom 939.

The gate position track mechanism may have as many slots/tracks (gate positioning slots/tracks) and positions as needed to provide the needed gate movement. For example, as shown in FIG. 8 at 807 has two gate positioning tracks which have three positions. The closed position is shown in FIG. 8 with the gate positioning bolts 808 in the position as noted (substantially in the middle of each slot). The flood position is shown in FIG. 9A with the gate positioning bolts 908 in the position as noted (substantially at the bottom of each slot). The drain position is shown in FIG. 9B with the gate positioning bolts 938 in the position as noted (substantially at the top of each slot). What is to be appreciated is that in this embodiment of the gate positioning track there are three positions, however, the invention is not so limited, and for example, if a gate only needs to close and flood then only two positions are needed, see for example, FIG. 11A. If a gate only needs to close and drain then only two positions are needed, see for example, FIG. 11B. Thus depending upon what is required there may be multiple tracks/slots and multiple positions for a gate positioning mechanism.

FIG. 10 consists of FIG. 10A and FIG. 10B.

FIG. 10A illustrates, generally at 1000, one embodiment of the invention showing a side view of a double gate in the closed position. At 1001 is a gate, at 1002 is an actuator, at 1003 a bracket, at 1004 a side dam, and at 1005 a ballast tank.

While FIG. 10 shows two gates, the invention is not so limited and in one embodiment either gate as shown in FIG. 10 may be an intake gate or an drain gate. Additionally in one embodiment there may be a single gate which opens/closes on one or more ballast tanks. For example in FIG. 7 there may be a single gate that opens/closes to openings 710, 712, 714, and 716 to allow for filling and emptying. Nor is the invention limited to two ballast tanks. There may be any number of ballast tanks. Additionally, there may be any number of gates, for example, 5, 6, 8, etc.

FIG. 11 consists of FIG. 11A and FIG. 11B.
