LIMB MOUNTING SYSTEM FOR ARCHERY BOW

摘要

An archery bow includes a bow riser, a limb, a limb bolt and a pivot pin. The bow riser is formed at one end with a rearward portion that includes a cradle and a bridge spanning the cradle to form a passageway therebetween and a tunnel defined in an inner wall of the bridge. The limb bolt attaches a butt end of the limb to a forward portion of the bow riser. The pivot pin passes through the passageway in the rearward portion of the bow riser and positioned in the cradle of the rearward portion of the bow riser. Moreover, the pivot pin defines in a top a pair of recesses in which two limb members of the limb are nested respectively, and is formed on a bottom a pair of positioning studs together clasping opposite ends of the cradle of the rearward portion of the bow riser.
