TECHNICAL FIELD

The present invention relates to archery equipment, and more particularly to an arrow nock that retains an arrow on the bowstring until the arrow is shot.

BACKGROUND

An arrow nock forms the rearward end of an arrow and generally has a pair of wings that form a notch for receiving the bowstring. An arrow nock without a notch is disclosed in U.S. Pat. No. 1,785,589 to Mead. The arrow nock is often made as a separate component that is affixed to the rearward end of the arrow shaft.

Arrow nocks with a notch having parallel sides or sides that diverge rearwardly can slip off of the bowstring as the bow is drawn. Many known arrow nocks have notches with sides that converge rearwardly to retain the nock on the bowstring. However, the rearwardly converging sides create frictional drag on the arrow during release from the bowstring.

U.S. Pat. No. 1,542,762 to Cole discloses an arrow nock where one of the wings is spring biased and pivots to accommodate different bowstring diameters. U.S. Pat. No. 3,034,789 to Moore discloses an arrow nock with a leaf spring to retain the arrow on the bowstring. U.S. Pat. No. 3,214,174 to Saunders discloses an arrow nock with a cavity forward of the notch that allows the wings to flex outwardly more easily during engagement and release of the bowstring. None of these arrow nocks eliminates frictional drag during release.

DISCLOSURE OF THE INVENTION

An arrow nock includes a nock body, a pair of retaining tabs, an actuator and a means for biasing the actuator rearwardly. The nock body has forward portion that affixes to the tail of an arrow, an intermediate portion and a pair of spaced wings that extend rearwardly from the intermediate portion. The actuator fits between the wings and is movable between rearward and forward positions. The retaining tabs are movable between a closed position and an open position, and are linked to the actuator such that when the actuator moves from the rearward position to the forward position, the retaining tabs move from the closed position to the open position. The retaining tabs retain the bowstring when in the closed position and clear the bowstring when in the open position. When the bowstring is released to shoot the arrow, the bowstring pushes the actuator to the forward position. The means for biasing is selected such that the retaining tabs remain in the open position until after the bowstring clears the arrow nock.
