ABSTRACT:
Astro capsule intended for use as a toy and raisable and rotatable on a four-bar linkage by hydraulic cylinders through hydraulic circuits. An electrical circuit provides for sequenced flashing flight lights, pulsating front gun lights, and for providing through a speaker a rocket sound and a phasor gun sound. The hydraulic circuits include a novel single spool for regulating flow through a valve between a combined motor pump tank to a cylinder at a fast speed up and slow speed down, and a hydraulically actuated system for rotating the capsule about its vertical axis. The vertical motion valve is mechanically linked to the joystick for ascending and descending motion and electrically controlled by the joystick for hydraulic actuation of the capsule about its vertical axis. The four-bar linkage includes a safety bar which overrides the joystick in the event that an individual or an object is positioned under the linkage in an elevated condition. Additionally, a safety switch positioned on the safety bar acts independently of the safety bar to trap fluid in the hydraulic cylinder to prevent its descent should an individual or object be positioned under the linkage in an elevated condition during or after the timed ride. The hydraulic circuit is provided with a joystick stop limit within the joystick throttle structure, a valve control stop link, a safety bar limit, a safety switch and solenoid shutoff valve, and the inherent four-bar linkage limit.
