Abstract
Certain preferred embodiments of the present invention use a dual constraint system to align an archery bow limb with a limb cup on a riser. Preferably the limb is aligned so that the centerline of the limb is aligned with the centerline of the riser. The plane of the limb is also constrained to facilitate this centerline alignment and to prevent excessive clearance between the limb, limb pocket and corresponding riser. In certain preferred embodiments, the present invention uses taper or wedge geometry in both the X-Y and X-Z planes along the length and separately along the depth of the limb cup engagement with the archery bow limb. Preferably this provides two complimentary locking mechanisms between the limb and limb cup.
