  • Patent number: 5931146
    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.
