Abstract

A bowstring mounted peep sight is disclosed having a peep housing that is frictionally located between displaced bowstring filaments. The peep housing defines a peep hole and a transverse oriented receiving slot. Insertable aperture reducing discs are slidably inserted into the receiving slot to incrementally decrease the relative aperture of the peep hole. To prevent the inserts from being inadvertently dislodged from the receiving slot during use of the invention, one of the displaced bowstring elements is positioned so as to prevent the disc from sliding outwardly therefrom. Because of the design of the peep housing, lightweight materials can be utilized. Frusto conical recesses on both planar surfaces of the peep housing reduce incidental glare thereby increasing the clarity of the observed target.

Claims6

Dependent claims

An adjustable aperture peep sight for mounting between filaments of an archery bowstring comprising:

a peep housing generally having two substantially planar exterior surfaces and a peripheral surface, said housing defining a peep hole having a central axis generally perpendicular to said exterior surfaces and defining a receiving slot, said slot inwardly depending from said peripheral surface of said housing to define an orifice and bounded by said housing, said housing further defining a plurality of bowstring filament receiving notches located at said peripheral surface whereby a corresponding number of filaments of a bowstring may be located therein when mounting said peep housing;
and
an aperture reducing disc, said disc being slidably receivable in said receiving slot in a direction substantially perpendicular to said axis of said hole, wherein at least one of said plurality of bowstring receiving notches is located at said orifice of said receiving slot to prevent ingress of egress of said aperture reducing disc when a bowstring filament is located therein.
