ABSTRACT:
A two-stage toy rocket and spring-loaded launcher assembly which when fired, propels the first stage into space. The first stage of the rocket is a missile molded of resilient plastic material having a solid disc mounted on its rear end encircled by a coupling collar. The second stage is formed by an externally-threaded sleeve whose upper end is received in the rear end collar of the first stage, and is releasable therefrom by a release button which, when actuated, then decouples the first stage from the second stage. The launcher is formed by a platform on which is anchored an internally-threaded shell whose diameter is such that it is threadably receivable in the sleeve of the second stage, a spring being nested in the shell and projecting thereabove. When a player turns the rocket to cause the threaded sleeve of the second stage to advance into the threaded shell of the launcher and thereby compress the spring then interposed between the disc at the rear end of the first stage and the platform, this action develops a strong latent force to cock the toy rocket. To fire the toy rocket, the player actuates the release button to decouple the first stage from the second stage, thereby causing the released spring to apply a powerful thrust force to propel the first stage into space.
