DESCRIPTION OF THE INVENTION 
This invention is directed to a water cannon that can be integrated into a scooter or attached to a scooter as an aftermarket accessory. Referring to FIG. 1, scooter 10 includes a standard 12 and a handle bar 14. A fluid reservoir 17 is carried by the scooter and in one embodiment, carried by standard 12. Fluid is transferred to a nozzle 16 through hose 18. Actuators 20 are used to pump fluid or to activate a pump for pumping fluid from the reservoir to the nozzle. In one embodiment, as shown in FIG. 1B, the fluid reservoir is attached to or integrated into the platform that supports the rider. The reservoir can have one portion 22 that is transparent so that the fluid level can be observed by the rider by looking at the reservoir through the platform. In another embodiment, as shown in FIG. 1C, the fluid reservoir is attached under the platform so that it is out of the way and does not interfere with riding the scooter. There can be one or more reservoirs included in the scooter. For example, there can be a standard mounted reservoir for a nozzle mounted on the handle and a platform mounted reservoir for a rearward facing nozzle mounted on the platform.
Referring to FIG. 2A, one pump assembly for transporting fluid from the reservoir to the nozzle is shown. One embodiment of actuator 20 is shown having a button 24 that can be pressed in a direction shown as 26. A spring 28 biases the button in a direction 27 so that the button will return to its original position after being depressed. The actuator includes opening 30 which is connected to the reservoir and opening 32 is connected to the nozzle. When the actuator is activated, fluid will travel from the reservoir to the nozzle.
In operation, and referring to FIG. 2B, the button is pressed and travels in direction 26. This creates pressure in a cavity 34. In reaction to the pressure, valve 36 opens and fluid is forced from the cavity outwards toward the nozzle through opening 32. The next step, as shown in FIG. 2C, spring 28 forces the button in a direction 27. This creates a vacuum in cavity 34 and forces valve 36 to close and valve 38 opens. This allows fluid to be drawn into the cavity from the reservoir to fill the cavity so that it can be forced to the nozzle when the button is subsequently pressed.
In one embodiment, shown in FIG. 2D, the actuator can be operated through a motorized assembly 40. Motorized assembly can include a wheel 42 and arm 44. When the wheel rotates, the combination wheel and arm cause a plunger 46 to move in a direction shown as 48, creating pressure in the cavity and creates a vacuum in the cavity to force fluid through the nozzle and draw fluid from the reservoir.
Referring to FIG. 3A, plunger 46 is forced in a direction 26 by the wheel and the arm when the wheel is turning in a direction shown as 50. Valve 36 is forced open by pressure created in the cavity and valve 38 is forced closed. Fluid is forced through opening 32 and through the nozzle. In FIG. 3B, the plunger is moved in direction shown as 27 creating a vacuum in the cavity. Valve 38 opens and valve 36 closes so that the vacuum draws water into the cavity from the reservoir. FIG. 3C shows the cycle beginning to repeat.
Referring to FIG. 4A, wheel 42 and arm 44 can be driven by a motor 52, such as an electric motor, connected to a switch 54 and power supply 56. When the switch is closed, the electric motor causes the wheel to rotate resulting in fluid being drawn from the fluid reservoir and forced out through the nozzle. In one embodiment, the switch 54 can be closed by a remote device that is wirelessly connected to the motor and its electrical circuit. When the wireless device is used to close the switch 54, the motor is actuated, thus causing the wheel 50 and arm 44 to move the plunger and directing fluid to the nozzle as described above. It should be understood that this invention is not limited to a single nozzle or that the nozzle be mounted only on the handles. Multiple nozzles can be used and nozzles can exist on the front, side or rear of a scooter. For example, a rear mounted nozzle can be positioned near the rear wheel and aimed to spray fluid upwards into a target that is positioned behind and above the rear wheel.
Referring to FIG. 4B, a nozzle attached to a handle is shown. The disadvantages with this design are that the handle bar needs to be turned from position 58 to position 60 so that the nozzle will spray in a direction shown as 62 from its original direction 64. This requires that the direction of the scooter be altered simply to change the direction of the spray of the nozzle.
In FIG. 4C, nozzle 16 is pivotally connected to the handle through pivot 66, allowing the nozzle to rotate in a direction shown as 68. A spring 70 biases the nozzle in a direction shown as 72 so that, in this embodiment, the nozzle tends to point to the left of the handles. Lever 74, when pressed, causes cable 76 to move in a direction shown as 78. This direction of force is accomplished since the cable is pulled around idler 80. Referring to FIG. 4D, the effect of the lever being pressed is shown. When tension is placed on the cable, the nozzle is pulled in a direction 78 resulting in the nozzle rotating counterclockwise and thereby aiming to the right on the handles. Therefore, the nozzle spray can be aimed without the need to move the handles and interfere with the direction of travel of the scooter. In one embodiment, shown in FIG. 4E, a plurality of levers are connected to the nozzle through cables so that when one lever is pulled, the nozzle rotates and changes the aim of the spray. The levers and nozzle can be arranged so that the right lever moves the nozzle right and the left lever moves the nozzle left, or the directions can be reversed.
Referring to FIG. 5A, another embodiment is shown wherein a gear is connected to nozzle 16 wherein nozzle 16 includes teeth 84. When the lever connected to the gear through the cable is pulled, the gear rotates in a direction shown as 86 causing the nozzle to rotate in an opposite direction causing the nozzle to aim to the left. When tension on the cable is removed, the spring connected to the gear pulls the gear in a direction opposite that of direction 84 and causing the nozzle to rotate in direction 86 and aim to the right. In FIG. 5B, the idler is not present and the cable causes the gear to rotate in a direction shown as 86 when the lever is pulled by switching the connection points of the cable and spring on the gear. In one embodiment, the direction of the gear rotation in response to the lever being pulled can be reversed.
Referring to FIGS. 6A and 6B, another embodiment of the invention is shown. In this embodiment, actuator 88 is carried by the rider's platform and can be activated upon pressure from the rider's foot. The actuator is connected to a manual pump or electric pump which will force fluid from the reservoir to the nozzle. Actuator 88 can force fluid to muzzle 16 carried by the handle or through nozzle 90, or both in combination. In one embodiment, the actuator 92 is a foot pump assembly that forces fluid from the reservoir out though the nozzle. In one embodiment, multiple actuators can activate pumps to force water through multiple nozzles both individually and in combination through a selector which can open and close valves to only allow fluid to travel to certain nozzles.
This invention is also directed to a water cannon that can be integrated into a skateboard or attached to a skateboard as an aftermarket accessory. Referring to FIG. 7, skateboard 110 includes a deck 112, trucks 114, and wheels 116. As is well known in the art, two trucks 114 are carried by the underside of the deck 112 and each set of trucks includes a set of wheels 116. A fluid reservoir 122 is carried by the skateboard and is in fluid communication with the nozzle 118. Fluid is transferred to a nozzle 118 through hose 120. Actuator 124 can be used to cause fluid to be pumped or to activate a pump for pumping fluid from the reservoir 122 through the nozzle 118. In one embodiment, the fluid reservoir 122 is attached to or integrated into the deck 112 that supports the rider.
The reservoir can have one portion 122 that is transparent so that the fluid level can be observed by the rider by looking at the reservoir. The fluid reservoir can be attached under or otherwise to the deck. When attached under the deck, the fluid reservoir it is out of the way and does not interfere with riding the skateboard.
Referring to FIG. 8, one pump assembly for transporting fluid from the reservoir to the nozzle is shown. One embodiment of actuator 124 is shown having a button 126 that can be pressed in a direction shown as 125. A spring 128 biases the button in a direction 127 so that the button will return to its original position after being depressed. The actuator includes opening 130 which is connected to the reservoir and opening 132 is connected to the nozzle. When the actuator is activated, fluid will travel from the reservoir to the nozzle.
Multiple nozzles can be used and nozzles can exist on the front, side or rear of a skateboard. For example, a rear mounted nozzle can be positioned near the rear of the deck and aimed to spray fluid upwards into a target that is positioned behind and above the deck.
Referring to FIG. 9A, another embodiment of the invention is shown. In this embodiment, actuator 188 is carried by the upper portion of the deck and can be activated upon pressure from the rider's foot. The actuator is connected to a manual pump or electric pump which will force fluid from the reservoir to the nozzle. Actuator 188 can force fluid to nozzle 118 carried by the front portion of the deck or through nozzle 190 carried by the rear portion of the deck, or both in combination.
As can be seen in FIG. 9B, in one embodiment, the actuator 192 is a foot pump assembly that forces fluid from the reservoir 122 out though the nozzle 118. In one embodiment, multiple actuators can activate pumps to force water through multiple nozzles, both individually and in combination, through a selector which can open and close valves to only allow fluid to travel to certain nozzles.
Referring to FIG. 9C, a receiver 200 can be connected to a pump so that when the receiver receives an “on” command, the pump is actuated and fluid is delivered to the nozzle. A transmitter 202 can include an antenna 204, actuation buttons 206a and 206b and at least one accelerometer 208. In operation, the transmitter can send commands to the receiver. If button actuator 206a is depressed, a front nozzle spray command can be transmitted and the front nozzle would deliver fluid. If the button actuator 206b is depressed, a rear nozzle spray command can be transmitted and the rear nozzle would deliver fluid. The directions of the nozzles can be determined by the spatial position of the transmitter. For example, the nozzle can be connected to a position member carried by the skateboard 110 so that the nozzle can be mechanically positioned in a particular direction by the position member. The position member can include gears or a ball and socket assembly for positing the nozzle. By moving the transmitter, the accelerometer can determine the direction of movement of the transmitter and transmit a movement command to the receive which will in turn actuate the positioning member and point the nozzle in the represented direction. Nozzles can be positioned in a 360° range of direction. In one embodiment, the transmitter is integrated into a glove worn by the rider. The glove can include safety features such as durable material for its construction, securing bands, and impact pads.
Fluid that can be delivered by the nozzles can include dyed fluid, or a fluid that interacts with an impregnated material so that when the material is moistened with the fluid, the material indicates that the fluid hit the material.
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 is, therefore, indicated by the appended 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.
