Patent ID: 7993224

Claim:
A lighted archery nock assembly adapted for attachment to an arrow comprising: an arrow nock; a replaceable battery including electrical contacts and an annular groove; circuitry including electrical contacts that selectively engage said electrical contacts of said replaceable battery to form an electrical connection, said circuitry including: an accelerometer that provides an accelerometer output indicative of acceleration of said lighted archery nock where the arrow is shot from an archery bow by a user; a light source visible through at least a portion of said arrow nock; and a controller that controls illumination of said light source as a function of said accelerometer output; a housing joined with at least one of said arrow nock and said circuitry, and selectively joined with said replaceable battery, said housing being elongate and generally tubular; wherein said housing includes a plurality of tabs terminating at corresponding inwardly protruding end projections, said inwardly protruding end projections selectively engaging said annular groove of said replaceable battery to ensure that said replaceable battery maintains contact with said electrical contacts of said circuitry; wherein said plurality of tabs define a battery holding aperture; wherein said plurality of tabs are deformable so that said plurality of tabs open from a closed position upon initial insertion of said replaceable battery into said battery holding aperture, but said plurality of tabs return toward the closed position to engage said annular groove of said replaceable battery, thereby holding said replaceable battery in a secured configuration relative to the nock assembly.
