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.
Claims22
An archery bow, comprising:
- an archery bow riser having a length with an upper end and a lower end;
- a pair of bow limbs, each bow limb having a proximal end and a distal end;
- a bowstring extending between the distal ends of said limbs;
- a limb pocket mounted on one end of said riser and restraining the proximal end of one bow limb, wherein said limb pocket has a seat portion and two opposing sidewall portions with a height defining a length and a depth of said limb pocket;
- wherein said limb pocket and said one proximal end of said bow limb have a matched taper along the length of said limb pocket to align said bow limb in a first plane;
- and,
- wherein said limb pocket has a taper matching or exceeding a taper of said proximal one end of said bow limb along the depth of said limb pocket to align said bow limb in a second plane perpendicular to said first plane.
A limb pocket for an archery bow, comprising:
- a seat portion to be mounted on an archery bow riser defining a front and a rear;
- sidewall portions with a height on opposing sides of said seat portion;
- said seat portion and said sidewall portions defining a pocket to receive an end of an archery bow limb;
- said pocket having a length and a depth;
- said pocket having an outward taper along said length from said front towards said rear;
- and,
- said pocket having an inward taper along the depth of said limb pocket.
A limb pocket for an archery bow, comprising a limb pocket bracket mountable on an archery riser and defining a pocket to receive an end of an archery bow limb, said pocket defining at least two tapered directions to wedgingly align the end of the archery bow limb in at least two directions.
