TECHNICAL FIELD
Various embodiments of the invention relate generally to water rocket toys and related methods.
BACKGROUND
Children and adults around the world have been enjoying toy rockets for decades. Among the most popular and simple to use are those that use pressurized water as a propellant. These water rockets typically include a hollow rocket body, or fuselage, which is partially filled with water, then connected to a manual hand pump that forces air into the fuselage, pressuring the water. The pressurized water can then be released from an escape nozzle at the base of the fuselage to launch the rocket skyward. The height the rocket reaches depends on numerous aspects of its design as well as the water pressurization, with heights in the 50 to 100 feet range being relatively common. The world record for a single-stage water rocket, set in 2007, is 2044 feet.
The present inventor recognized that conventional water rockets provide great initial excitement that wanes rapidly over time, with many children potentially losing interest after only several uses. The problem is compounded in view of the competition from other types of toys, such as video games, that tend to offer a more varied and ever-changing experience.
Accordingly, the present inventor has recognized a need for alternative forms of water rockets that offer greater interest and fascination.
SUMMARY
To address one or more of these and/or other needs or problems, the present inventor devised, among other things, one or more exemplary water rocket systems, kits, methods, devices, assemblies, and/or components.
In one exemplary embodiment, the invention takes the form of a water rocket assembly having a removably mounted action figure with the action figure configured to be launched simultaneously with the water rocket. In some embodiments, the water rocket includes two hollow fuselage structures joined via a crossbar structure. In some embodiment, the crossbar structure is hollow and in fluid communication with the two fuselage structures, allowing simultaneously filling of the fuselage structures with water. In some embodiments, the fuselage structures rest on a launch platform having a pair of launch tubes, with each of the tubes extending upward from the platform through an exhaust nozzle of a corresponding one of the fuselage. The launch tubes are fluidly coupled to a common pressure source, such as a hand pump, enabling simultaneous pressurization of the two fuselage structures. In still other embodiments, the two fuselages are mechanically connected via a cross retaining bar and the cross retaining bar engages with a latch that is remotely triggerable via a mechanical actuator.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT(S)
This document, which incorporates drawings and claims, describes one or more specific embodiments of one or more inventions. These embodiments, offered not to limit but only to exemplify and teach the invention, are shown and described in sufficient detail to enable those skilled in the art to implement or practice the invention(s). Thus, where appropriate to avoid obscuring the invention(s), the description may omit certain information known to those of skill in the art.
FIG. 1 shows a water rocket action figure system or assembly 100. Assembly 100 includes a launch platform assembly 110, a water rocket assembly 120, and an action figure 130.
Launch platform assembly 110, which is generally formed of injection molded plastic and machined metal, includes a base 111, legs 112A-112D, trigger assembly 113, pressurization assembly 114, and launch tubes 115 and 116. Base 111 provides a flat support surface, which is elevated via four legs 112A-112D, with leg 112D visible only in FIGS. 2 and 3. Trigger assembly 113 includes a pistol style hand-squeezable trigger mechanism 113A, a Bowden type cable linkage 113B, a coupling member 113C, a linkage 113D, and a rocket retaining latch 113E. Pistol style trigger mechanism 133A is coupled via Bowden cable linkage 113B to coupling member 113C and then through a linkage 113D, shown best in FIG. 3, to rocket retaining latch 113E. Actuation of the trigger mechanism 113D pulls the internal cable of the Bowden cable linkage, lifting the retaining latch, which is spring biased in a closed or latched position in the exemplary embodiment over a retaining crossbar 124.
Pressurization assembly 114 includes a pressure source 114A, a pressure hose 114B, and a coupling member 114C. Pressure source 114A, which can take the form of a manual hand or foot pump, a motorized pump, or pressurized air or other gas canister, is in fluid communication via coupling member 114C with duct or conduit structure 114D on the underside of base 111 (shown best in FIG. 3.) Coupling member 114C takes the exemplary form of a Schrader or Presta type of valve connection. However, some embodiments use other forms of hose and one-way valve connections. Duct structure 114D branches to fluidly couple pressure source 114A with launch tubes 115 and 116, which feed upward from base 111 into respective rocket tanks 121 and 122 of water rocket assembly 120.
In addition to rocket tanks (or fuselages) 121 and 122, and retaining bar 124, water rocket assembly 120 includes a crossbar tank 123. Rocket tanks 121 and 122, which have central axes aligned respectively with launch tubes 115 and 116, are mechanically joined by and fluidly coupled via crossbar tank 123. Crossbar tank 123 includes a screw-off cap 123A, which is removable to allow simultaneous and even filling of rocket tanks 121 and 122 with water or other desired fluid. Some embodiments provide separate fill ports for each of the rocket tanks, for example via allowing the conical tips of the rocket tanks to be threaded off. Some embodiments also allow the rocket tanks to operated independently via providing separate triggers, retaining latches, and retaining bars or catches and allowing separation of the rocket tanks from the crossbar tank and common retaining bar. In some of these embodiments, the crossbar tank snap fits onto rocket tanks. Attached to crossbar tank 123 is action figure 130.
Action figure 130 includes a human-like body 131, a helmet 132, and a harness structure 133. Human-like body 131 includes two articulable arms, two articulable legs, and a head. The head is covered via a helmet 132, which includes a goggle region 132A and an embedded battery-powered digital video camera module 132B. Goggle region 132A includes an opening for the camera sensor, and the digital vide camera module includes an accelerometer and/or altitude sensor as well as wireless transmission circuitry, for example Bluetooth circuitry to enable wireless communication of video images to a paired smartphone or other Bluetooth compliant receiver. In some embodiments, one or more portions of the camera module are distributed into the torso region of body 131. The torso region is fitted into harness structure 133, which snap fits or otherwise removably attaches to a front portion of crossbar tank 123. In some embodiments, harness structure 133 includes a rear-mounted parachute 133A, which deploys in response to active or passive accelerometer or inertial sensors. In some embodiments parachute 133A is mounted on the front of harness 133A. In some embodiments, harness 133A, for example, the parachute includes a radio-controlled (e.g., Bluetooth controllable) quadcopter drone, which allows a user to fly the rocket action figure assembly and/or the action figure under control of a smartphone or other compatible controller.
In exemplary operation, a user fills rocket tanks 121 and 122 simultaneously with water via crossbar tank 123. When filled the user tightens cap 123A and attaches pressure hose 114B to coupling member and then pressurizes the tanks to a desired pressure. Some embodiments include pressure relief valves to prevent over pressurization of the tanks. Once pressurized, the user can stand away from the platform 111 and actuate trigger mechanism 113D. Actuating the trigger mechanism pulls the internal cable of Bowden cable linkage 113B, lifting the retaining latch 113E away from retaining crossbar 124 and allowing rocket action figure assembly 120 to separate from platform 110 under the joint propulsive force of the pressurized water from tanks 121 and 123. Once the rocket action figure assembly reaches a desired height or the apex of its flight, inertial sensors trigger operation of camera module 132B and/or parachute 133A. In some embodiment, camera module 132B is triggered via initial movement of rocket action figure assembly.
In some embodiments, action figure 130 is replaced with an alternative cargo or payload structure that snap fits onto the crossbar structure. In some embodiments, the payload structure includes wirelessly controllable payload doors to allow dropping a payload remotely.
