Two Stage Rope Cocker For Crossbow

Abstract

A two-stage rope cocker for a crossbow includes a bowstring carrier, a midway retainer, at least one handle and a cord. The bowstring carrier is slidably engaged with a rail of the crossbow. The midway retainer is pivotally engaged with the rail. Each handle includes a spring-motor engaged with a spool. A first end of the cord is retained on a first spool and a second end of the cord is retained on a second spool. A length of the cord is retained on the bowstring carrier. First and second spring-motors bias the first and second spools to wind the cord on the first and second spools. Pulling first and second handles translates the bowstring carrier from a distal position to the midway retainer. The first and second handles are pulled to translate the bowstring carrier from the midway retainer to a ready to fire position.
