DETAILED DESCRIPTION

(10) Certain terminology is used in the following description for convenience only and is not limiting. The article a is intended to include one or more items, and where only one item is intended the term one or similar language is used. Additionally, to assist in the description of the present invention, words such as top, bottom, side, upper, lower, front, rear, inner, outer, right and left are used to describe the accompanying figures. The terminology includes the words above specifically mentioned, derivatives thereof, and words of similar import.

(11) Referring to the figures, embodiments of the toy ship of the present invention are shown. The toy ship of the present invention will also be referred to as Sinkable Toy Warship throughout the specification.

(12) As shown in FIG. 1, the invention is made with a stable, wide hull that will maintain a generally upright position when turning and when water accumulates in its body. FIG. 2 (left side), shows a front view with the hull having two chines, 22, running along the sides of the hull and deepest in the rear of the boat for stability, and a deeper V-shaped middle, 23, that runs the entire length of the hull. For deeper water and additional stability in rough water, a modified keel, 24, shown in dotted lines, runs the length of the boat but is deepest near the middle. The keel, 24, is modified to be hollow and wider so that it can collect water that enters from above and provides the boat with ballast and stability even while it is slowly being sunk by an opponent.

(13) FIG. 1, shows the shooting mechanism which starts at an inlet or intake, 3, moves through a hose, 4, into a driving mechanism or a pump, 5, and up through the nozzle, 6, into a conduit or gun tube, 7, and out of an output device or cannon, 1, through a cannon end, 18, as shown in FIG. 2. Importantly, the intake, 3, will provide a counter-balancing force when made to face the same direction as the cannon, 1. In the figure it is shown to be pulling water in from the front which pulls the boat forward, while the cannon, 1, pushes water out of the front, which pushes the boat backwards. The net result is a muted effect on the boat's position during the cannon's operation.

(14) A gun turret, 37, shown in FIG. 6, can also be used to hold additional or alternate guns pointing in other directions, such as towards the starboard and the port sides simultaneously. FIG. 5, item 2, shows the positioning hole for such an alternative arrangement for the guns. In addition, to allow the player to quickly change the gun during play, the turret top can be made to be removable after unscrewing a thumbscrew, 38, and exposing the connection with the gun hose, 7.

(15) Referring to FIGS. 1 and 2, the boat includes one or more driving mechanisms or motors, 15, which may be electric or fuel powered, and which are housed within a motor housing, 20. In FIG. 1, item 16, two output devices or propellers are shown installed slightly below the hull bottom. This arrangement provides extra maneuverability because the propellers are more effective for reversing direction when the water flow from the front to the back is unobstructed (or at least less obstructed) by the boat hull itself. This is especially important to the Sinkable Toy Warship because reverse is used often when in battle, and, it should not result in backsplash that runs up and over the back of the hull.

(16) Batteries, 11, may be used as a power source and should be mounted near the middle of the boat due to their weight. Alternatively, the boat may be solar or gas powered.

(17) In a watertight compartment, a receiver and controller on a circuit board, 9, would be safely mounted and wired to an antenna, 10, the motor(s), 15, the pump, 5, and optionally a rudder. The remote-control receiver must be set to the same frequency as the remote controller and should have additional channels for each action, including the firing of the gun or guns.

(18) Wiring is made waterproof by protecting the connections within the watertight compartment, 8, and, the watertight compartments themselves are protected from leaks through the use of wire conduits, 12, 13 and 14, which provide an entry way for wires and an extended channel into which waterproofing material, such as silicone or adhesives, can be injected. The silicone can then envelope the wires within the wire conduits while providing a seal at both ends. For additional protection, the pump, which is itself waterproof and submersible, can have its wiring run into the battery compartment through one conduit, 12, and then out through another conduit, 13, before finally entering the waterproof compartment and connecting to the circuit board, 9. Effectively, this design prevents water from entering the waterproof compartment as it requires water collected in the hull of the boat to go through the two conduits and the battery compartment before it can enter the circuit board compartment.

(19) Sinkable Toy Warships are designed to absorb water rather than repel it and therefore will have multiple entry points, 25, on the deck, 17, through which water will drain into the hull, as shown for example in FIG. 2. In larger boats, as shown in FIG. 3, or other small embodiments, the majority of the deck can simply be omitted, thus providing water ample room to enter the hull, as shown for example in FIG. 3. That is, voids, 25, are provided on the deck, 17, so that water can enter the hull and accumulate therein.

(20) When necessary, a gun bib, FIG. 3, 26, can be installed below active guns, 1, that may dribble into their own hulls. Such a gun bib would include a retaining wall, FIG. 2, 19, to keep the water from rolling back into the hull, a sloped surface, and a drainage hole, 27.

(21) During play, boats of equal strength can battle each other in small, indoor pools, FIG. 4, 28. Such pools can be made small enough to be placed on a tabletop or floor, and the guns can be mounted so that water shot from the guns, 29, are restricted to lateral or downward movement such that it cannot be shot outside of the playing arena. Furthermore, the guns, 29, will not work once the boat is removed from the pool because the pool is in fact their only source of water or ammunition. The pump, 5, can still be activated but no water can be pushed out through the gun, 29. The result is that boats will move about and shoot at their opponents and the water will only be able to hit a target, 30, and sink their opponents as intended.

(22) Also, the players could determine that a particular ship has lost when the entire hull is submerged, i.e., when ship is still floating but the deck, 17, is under water. In the alternative, a pressure sensor or moisture sensor could be operably coupled to the circuitry so that when water is detected at the top of the deck or higher pressure is detected at the bottom of the deck the sensor could sound an alarm and/or disable the power source and/or the receiver such that the ship is deactivated.

(23) The invention can be played with on any body of water, including small pools, large pools, ponds, lakes and salt water. When it is intended for play in deep water the invention will be made to include built in deck structures or floatation devices in the form of extra-large, watertight voids, FIG. 5, items 31, and FIG. 2, item 21, which would require displacement that is greater in weight than that of the boat and its components. By mounting these floatation cavities, 31, on the deck, much of the boat is still allowed to sink below the surface and become incapacitated but the topside buoyancy will ensure that it will still be near the surface where it can be located and recovered.

(24) Larger environments are ideal for team play, where a team may be equipped with a fleet of boats with varying specialties, such as a battleship with strong guns and a deep hull but weak speed and maneuverability, and a destroyer with weak guns and a smaller hull but strong speed and maneuverability. Obstacles can be added to challenge the boat operators and provide areas with cover from fire. And targets can be used as the objective. For example, a large, defenseless boat may be the target of each team and must be protected from enemy fire. Sinking the target can be used as the final indicator of team victory.

(25) In an alternate embodiment shown in FIG. 6, the motor, 33, can be used in a jet propulsion channel, 34, to drive an impeller, 32, which pulls water through the channel and out the back of the boat for forward movement. In this alternate arrangement the motor, 33, can be put into reverse and thus act as an axial pump which now pulls water in from the rear of the boat, against a check valve, 35, which automatically closes, driving water up through the gun tube, 36 and out through the turret, 37. The benefit of such an arrangement is two-fold, first it eliminates the need for a pump and the third motor within it, and second, it eliminates the need for a separate remote-control function for reversing and shooting because when the motor is reversed it will in fact result in both actions: the gun shoots water forward, and in so doing, it also pushes the boat back. That reactive force is magnified by the water being pulled in from the back of the boat, resulting in an even stronger reversing effect.

(26) In other alternate embodiment, the gun can be fired through the use of a diaphragm pump that provides intermittent fire. Similarly, a pulsating pump can be used to make the weapon act like a machine gun. If large shots are preferred, for example for a large battleship, a reservoir or bladder can be filled by a pump or gravity and, once it is full and therefore armed, the bladder can be rapidly pressurized by a spring mechanism or actuator pressing up against its sides, thus forcing the water out of the weapon it is connected to. Such weapons would have faster, larger bullets but would not be continuous.

(27) Optionally, the Sinkable Toy Warship may have built-in pressure or moisture sensors in their hulls which can be used to sound an alarm when a boat is in danger of sinking. Sound effects can also be triggered when the gun is fired to enhance the experience and illusion of a real battle.

(28) The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention will be, therefore, indicated by claims rather than by the foregoing description. All changes, which come within the meaning and range of equivalency of the claims, are to be embraced within their scope.
