Toy with spring-loaded inner vehicle
摘要:
A toy is disclosed having a spring-loaded inner vehicle or projectile therewithin. An outer shell surrounds the inner vehicle, and the outer shell has a base at one end thereof constituting the rear of the shell. A spring is interposed between the inner vehicle and the base for resiliently biasing the inner vehicle away from the base in a forward direction. The outer shell has a portion thereof movable with respect to the base between a closed position in which the outer shell at least in part encloses the inner vehicle and holds the inner vehicle fixed with respect to the base while maintaining the spring in its compressed state, and an open position in which the shell portion is clear of the inner vehicle such that the spring may propel the inner vehicle forwardly with respect to the base portion.
