Abstract:
A hand-launched toy rocket, comprising:a cylindrical main body tube, said main body tube being open at both the top end and the bottom end, said main body tube having a body tube support ring attached at the top end of said main body tube; at least three rocket guide fins firmly attached by mounting means to the outer cylindrical surface at the bottom end of said main body tube, said guide fins being equally spaced around the perimeter of said main body tube; a spring support pin firmly attached in through-holes located near the bottom end of said main body tube, said spring support pin being installed by press fit means; a compression spring inserted from the top end of said main body tube, said compression spring being supported at the bottom end of said main body tube by said spring support pin; a cylindrical inner slide tube, a solid compression spring interface plate firmly attached to the bottom end of said inner slide tube, said inner slide tube being slidably mounted inside said main body tube from said top end allowing said spring interface plate to rest on top of said compression spring, said inner slide tube further having closed-end aligning guide pin slots cut on each side of said inner slide tube and extending most of the height of said inner slide tube; a solid inner tube guide pin firmly attached in through-holes located near the top end of said main body tube through said aligning guide pin slots in said inner slide tube, said inner tube guide pin being installed by press fit means; a solid material nose cone attached to the top of said inner slide tube by means of an adapter ring, said nose cone having a weight embedded in said solid material; a tether ring mounted to the bottom end of said main body tube; a launching tether tied to said tether ring for hand-launching said rocket; and a launching handle attached to the outer end of said tether, whereby said rocket is hand-launched into the air along an initial flight path, landing on said nose cone to force said inner sliding tube against said compression spring, thereby storing potential energy in said compression spring, said potential energy being sequentially released by said compression spring to self-launch said rocket along a second flight path.
