Patent attributes
A nock assembly for use with a crossbow bolt includes a nock body defining a notch into which the bowstring of a crossbow is insertable. A light assembly includes a switch member at one end of the notch. First and second spherical caps protrude into the notch and define a first gap therebetween. Third and fourth spherical caps protrude into the notch and define a second gap therebetween. The bowstring is positionable between the spherical caps such that the first and second spherical caps resist movement of the bowstring out of the notch, and the third and fourth spherical caps resist movement of the bowstring toward the switch member. Release of the bowstring from its cocked or drawn position causes the bowstring to pass through the second gap and contact the switch member to turn on the light assembly.
