Abstract
A water propelled hover toy (10) comprises a circular body (24) with a fluid supply chamber (36) affixed thereto. The body (24) is rotatably secured at an inlet port to the supply chamber (36) to a launch tube (12), which is connected to a water line by means of tubing (14). The sections of tubing (12, 14) are preferably coupled together by means of a rotary connection (22). In each of the embodiments, the body (24) is preferably configured to generate lift during rotation.
Claims9
A rotatable tethered hover toy adapted for use with a grounded source of water under pressure, comprising:
- a fluid supply chamber having a central longitudinal spin axis extending therethrough;
- said fluid supply chamber having a bottom end with an inlet coaxial with the spin axis, and plural outlets arranged substantially symmetrically with said spin axis;
- a circular rim independent of said fluid supply chamber and surrounding said fluid supply chamber;
- structure rigidly connected between said fluid supply chamber and rim for generating lifting force upon rotation with said fluid supply chamber and rim about the spin axis;
- a first tubing section having upper and lower ends;
- a first rotary connection coupled between the upper end of said first tubing section and the inlet of said fluid supply chamber;
- a second tubing section having upper and lower ends and being relatively longer than said first tubing section;
- a second rotary connection coupled between the lower end of said first tubing section and the upper end of said second tubing section;
- the lower end of said second tubing section being adapted for connection to the grounded water pressure source;
- and
- a plurality of generally radially extending fluid discharge conduits each having an inner end connected to an outlet of said fluid supply chamber and an outer end, the outer ends of said conduits terminating at said rim and being oriented downwardly and outwardly such that reaction forces due to water discharging therefrom cause said rim, fluid supply chamber and connecting structure to spin and hover while tethered by said first and second tubing sections.

- said fluid supply chamber having a bottom end with an inlet coaxial with the spin axis, and plural outlets arranged substantially symmetrically with said spin axis;
- a circular rim independent of said fluid supply chamber and surrounding said fluid supply chamber, said rim having plural circumferentially spaced openings therein;
- a dished body rigidly connected between said fluid supply chamber and rim for generating lifting force upon rotation with said fluid supply chamber and rim about the spin axis;
- said dished body having convex and concave surfaces and plural circumferentially spaced openings with associated flaps oriented in the spin direction for gathering air;
- a first tubing section having upper and lower ends;
- a rotary connection coupled between the upper end of said first tubing section and the inlet of said fluid supply chamber;
- the lower end of said first tubing section being adapted for connection to the grounded water source;
- and
- plural generally radially extending fluid discharge conduits each having an inner end connected to an outlet of said fluid supply chamber and an outer end, the outer ends of said conduits extending through the openings in said rim and being oriented downwardly and outwardly such that reaction forces due to water discharging therefrom cause said rim, fluid supply chamber and body to spin and hover while tethered by said first tubing section.
