Arrow rest with decoupled launch assembly

Abstract

An arrow rest with a decoupled launch assembly comprises a rest rotatably mounted to a shaft and coupled to the shaft via a biasing device. An actuator connects the shaft to a portion of a bow allowing movement of the bow to actuate the decoupled launch assembly between a raised state and dropped state by rotation of the shaft. The biasing device flexibly couples movement of the rest and shaft permitting the shaft to further rotate after a dropped state has been achieved.
