First Claim
Patent Images
1. An arrow assembly comprising:
- a solid arrow shaft extending along an axis and having a conically tapered rear end;
an adapter having a forwardly open conical bore receiving the rear end of the arrow shaft to align an axis of the adapter with the arrow axis by interfitting of the conical bore and tapered rear end and having a rearwardly opening bore with substantially parallel walls; and
a nock having a bifurcated rearward portion providing opposed fingers for fitting a bowstring therebetween and having a forwardly extending boss adapted to press fit within the rearwardly opening bore of the adapter to align the nock with the arrow axis;
wherein the nock provides a maximum diametrical extent less than a diameter of a cylindrical outer periphery of the adapter.
