Abstract
A bow tension relieving device that is useful with a bow that has a riser with opposing riser ends, has a first limb connected with a first riser end and extending in a direction that is generally away from a second riser end, and has a second limb connected with the second riser end and extending in a direction that is generally away from the first riser end. Each of the limbs also has an inner limb end at the riser. The bow tension relieving device has a coupling interconnecting the riser and one of the limbs. The coupling is actuatable between first and second positions to rotate the one limb a predetermined amount in a first rotational direction to decrease an effort of drawing the bow to a shooting position in the first position, and to rotate the one limb a predetermined amount in a second, opposing, rotational direction to increase the shooting force to a predetermined maximum level in the second position. The bow tension relieving device also has an actuator operatively connected with the coupler to actuate the coupler between the first and second positions. The actuator has a bias device that is operatively connected with the coupling and has a trigger that is operatively …
