ABSTRACT:
A novel limb construction for a compound archery bow including a handle riser and a bow limb with a base portion attached to the handle riser. The bow limb comprises a pair of resilient limb members connected to and integral with the base portion of the limb. Where the base portion joins two independent limb portions, a fork is formed. The bow limb also includes a working portion, which is an area of reduced thickness between the base of the limb and pulley. The majority of the flexing of the bow limb occurs at this working portion during the draw of the bowstring. In the present invention, the fork is on the base side of the working portion rather than the pulley side of the working portion, as with bows of the past. This design provides a lightweight bow which is strong and has many fewer parts compared to the split limbs of the past. The split limbs are stronger than a solid limb and can be made from various types of fiber reinforced plastics such as short and long fiber reinforced nylon.
