US12687370 - Operational structure and methods for torsion-driven, counter acting block and tackle type energy storage and deployment systems

An operating system of an arrow launching device utilizes the combination of a speed-limited winch together with a nock-release and passive fall away arrow rest within torsion-driven compact arrow launching devices that employ counter-acting block and tackle propulsion. The system enables a novel method of cocking, firing and de-cocking that improves safety, enhances reliability and increases efficiency.
