Archery bow and archery bow cam

摘要

An archery bow and cam apparatus having an anti-rotation cam stop mechanism which permits loosening of the bow string, loosening of a cable, or loosening of the bow string and a cable. The anti-rotation means may comprise an aperture or series of apertures through the cam and a member insertable in the aperture. The member can extend through the cam assembly and contact the limb of the bow to prevent the cam from rotating back to a resting or static position. The invention is particularly suited for a compound bow or compound crossbow having one or more cams, and a combination of a bow string and power cable, such the bow string may be detensioned by increasing the tension on the power cable, and vice versa, upon stopping free rotation of the cam.

主权项

1. A cam for engaging a bow string and power cable of an archery bow, the archery bow having opposed limbs, the cam comprising:
a cam body; a mount for rotatably mounting the cam body to one of said limbs about an axis; at least one first cam surface on said cam body for receiving the bow string; at least one second cam surface on said cam body for receiving the power cable; and a selectively actuatable cam stop to prevent rotation of the cam about said axis in a first direction beyond a first circumferential position when the cam is rotated in a second direction opposite the first direction and the cam stop is actuated, wherein actuation of the cam stop decreases tension on said bow string or said power cable when engaged to said cam surfaces and increases tension on the other of said bow string or said power cable, and deactuation of said cam stop permits free rotation of said cam body about said axis in either direction to restore tension on said bow string or power cable, the cam stop comprising at least one aperture within the cam body and a member configured to fit within said aperture, which when actuated, protrudes outwardly from both sides of the cam to contact first and second forks of the limb when said cam is mounted to said limb in order to prevent rotation of said cam in said first direction.
