Various embodiments of the invention relate generally to water rocket toys and related methods.
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.
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.
Various embodiments are described herein with reference to the following attached figures (Figs). These figures are annotated with reference numbers for various features and components, and these numbers are used in the following description as a teaching aid, with like numbers referring to the same or similar features and components.
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.
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
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
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
Action
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
In the foregoing specification, specific exemplary embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings.
The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
Moreover in this document, relational terms, such as second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has”, “having,” “includes”, “including,” “contains”, “containing” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises a”, “has . . . a”, “includes . . . a”, “contains . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially”, “essentially”, “approximately”, “about” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1% and in another embodiment within 0.5%. The term “coupled” as used herein is defined as connected, although not necessarily directly and not necessarily mechanically. A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed. Also, the term “exemplary” is used as an adjective herein to modify one or more nouns, such as embodiment, system, method, device, and is meant to indicate specifically that the noun is provided as a non-limiting example.
