ABSTRACT:
A lighted nock is provided for an arrow which undergoes an initial acceleration when shot from a bow and thereupon reaches a zero acceleration during flight shortly in front of the bow. The nock is formed of transparent material within which is embedded a light emitting diode. An elongate cavity is positioned within the forward portion of the nock and within that cavity there is slidably located an elongate battery having a rod-shaped forward electrode and a rear face forming a second electrode. An energy storing spring is positioned within the cavity and a second cavity is positioned adjacent the first cavity. Within the second cavity there is located an electrical contact and between the two cavities is a position delimiter formed as an annular silicone ring. As the arrow is shot, the energy storage spring moves into compressive contact with the rearward face of the battery and is compressed to store energy sufficient, upon the arrow reaching zero acceleration, to cause the battery forward rod-shaped end to penetrate the position delimiter and close a circuit. Electrical contact between the second terminal of the diode and the battery is provided by an elongate spring of low spring rate positioned coaxially within the energy storage spring and maintaining continuous abutting contact with the rearward face or terminal of the battery.
