ABSTRACT:
A trigger device for facilitating pulling of a bow string and for quick release of the taut bow string for propelling an arrow from the bow, said trigger device comprising a main body portion provided with suitable finger receiving recesses and a secondary body portion substantially perpendicular to the main body portion having a bow string hold and releasing latch mechanism carried thereby. The latching mechanism comprises a flexible loop member adapted for encircling the bow string and engaging a loop receiving recess provided in the secondary body portion. A latch member extends across the open end of the loop receiving recess and is operably connected with a release trigger by way of a pivotal bell crank and a lever member whereby a light touch of the trigger member by the finger of the archer quickly causes the bell crank and lever member to operate to release the latch member for release of the taut bow string.
