Patent attributes
A nock body may include a first end and an opposing second end. A nock housing may include a proximal end that engages the first end of the nock body and a distal end opposite the proximal end. A slot may be defined in the nock housing beginning at the distal end that extends in a direction of the proximal end. An LED/battery assembly may be disposed at least partially inside of the nock housing. A fastener may be secured to the nock housing in a location that causes a width of the slot to narrow and secure the LED/battery assembly. A groove may be defined in the nock body beginning at the first end that extends towards the second end. A nock activation lockout can be provided to block an LED activation gap from closing so that the LED does not unintentionally turn on.
