Abstract

A compound bow using a toggle link assembly to provide improved arrow speed, greater accuracy and improved ease of tuning and use. The bow basically includes first and second spaced bow limbs having a bowstring extending between their outer ends and having their other ends attached through power links to the opposite ends of a main riser. An adjustable connection between the limbs causes them to move in unison. A power canister is secured to the riser adjacent to one of the limb attachments. A toggle link assembly is connected between a power storage compression spring in the canister, and a link on the adjacent limb. As the bowstring is drawn with an arrow in the conventional manner, the toggle link assembly causes energy to be stored in the canister, such as by compressing the spring. When the bowstring is released, the stored energy imparts acceleration to the arrow through the toggle link assembly, limbs and bowstring. Details of a preferred toggle link assembly, an adjustable inter-limb connector, adjustable arrow rest and adjustable sight are also disclosed.
