Archery peep sight
摘要:
An archery peep sight adapted to be mounted on the bowstring of an archery bow for aligning the path of an arrow. A disc having a centrally located sight opening is attached to the bowstring in fixed space relation with the nocking point on the bowstring. The axis of the sight opening is coextensive with the axis of the disc and is located on the central plane of the disc. A frusto-conical surface is disposed inwardly from a first end of the disc, the apex thereof being terminated at the sight opening. A semi-conical recess is formed in the second end of the disc, the recess defining a horizontal planar surface adjacent the sight opening. Bowstring receiving channels are formed on opposite sides of the disc, the angular interval between a line normal to the bowstring receiving channels and the axis of the sight opening of the disc being in the range of 38.degree.-50.degree..
