Abstract
A bowstring release device comprising a first housing; a pair of spring biased gripping arms pivotally secured within the first housing for movement toward and away from each other, the gripping arms each having at least one jaw; ball actuator means mounted in the first housing for moving the gripping arms between open and closed positions; a second housing secured to the first housing and axially aligned therewith; a firing pin slidably mounted in the second housing and adapted for engagement with the actuator means; and a handle mechanism secured to the second housing and including an element adapted to operatively engage the firing pin.

- and
- a handle mechanism secured to said second housing and including an element adapted to operatively engage said firing pin.
4 more elements
A bowstring release device comprising:
- a first housing;
- a pair of spring biased gripping arms pivotally secured within said first housing for movement toward and away from each other, wherein each gripping arm is provided with a pair of jaws, each comprising a substantially semi-spherical socket adapted to engage a corresponding pair of substantially ball-shaped nocks;
- a ball actuator mounted in said first housing between said gripping arms;
- a second housing secured to said first housing and axially aligned therewith;
- a firing pin slidably mounted in said second housing and adapted for engagement with said ball actuator so as to move said ball actuator axially toward said jaws and to thereby permit said gripping arms to move to an open release position;
- and
- a handle mechanism secured to said second housing and including an element adapted to operatively engage said firing pin.
4 more elements
A bowstring release device comprising:
- a first housing;
- a pair of spring biased gripping arms pivotally secured within said first housing for movement toward and away from each other, said gripping arms each having at least one jaw;
- a ball actuator mounted in said first housing, between said gripping arms, for causing said gripping arms to move between open and closed positions, wherein said ball actuator is engaged by one end of a spring which biases the ball actuator in a direction corresponding to said closed position;
- a second housing secured to said first housing and axially aligned therewith;
- a firing pin slidably mounted in said second housing and adapted for engagement with said ball actuator;
- a handle mechanism secured to said second housing and including an element adapted to operatively engage said firing pin;
- and
- wherein said gripping arms each include a surface engaging an opposite end of said spring and located intermediate forward and rearward ends of said gripping arms, and another surface engaging said ball and located between said spring and said rearward end.
5 more elements
A bowstring release device comprising:
- a first housing;
- a pair of spring biased gripping arms pivotally secured within said first housing for movement toward and away from each other, said gripping arms each having at least one jaw;
- ball actuator means mounted in said first housing for moving said gripping arms between open and closed positions;
- a second housing secured to said first housing and axially aligned therewith;
- a firing pin slidably mounted in said second housing and adapted for engagement with said ball actuator means;
- and
- a combined handle and trigger mechanism pivotally secured to said second housing for rotation about an axis perpendicular to said common center axis, and including an element adapted to operatively engage said firing pin;
- and further
- wherein said combined trigger and handle mechanism includes a hand grip and a hinge pin threadably secured in said hand grip and projecting from said hand grip, said hinge pin being pivotally mounted in said second housing, and wherein said hinge pin includes adjustable means for engaging said firing pin.
6 more elements
A bowstring release device comprising:
- a first housing;
- a pair of spring biased gripping arms pivotally secured within said first housing for movement toward and away from each other, said gripping arms each having at least one jaw;
- ball actuator means mounted in said first housing for moving said gripping arms between open and closed positions;
- a second housing secured to said first housing and axially aligned therewith, and wherein said first housing is freely rotatable relative to said second housing about a common center axis;
- a firing pin slidably mounted in said second housing and adapted for engagement with said ball actuator means;
- and
- a handle secured to said second housing and including a trigger member pivotally secured within an open slot along a rearward face of the handle, said trigger member adapted to operatively engage said firing pin;
- wherein said handle mechanism is secured to said second housing for rotation with said second housing relative to said first housing about said center axis, said handle including a trigger member pivotally secured thereto, said trigger member adapted to operatively engage said firing pin;
- and further wherein said handle includes a second firing pin extending through said handle and into engagement with said first firing pin.
6 more elements
A bowstring release device comprising:
- a housing;
- a pair of gripping arms, each having at least one jaw and each having ball engagement surfaces thereon;
- said arms pivotally secured in said housing for movement between closed gripping and open releasing positions;
- a ball actuator mounted in said housing and movable axially along grooves formed in said housing and along said ball engagement surfaces of said gripping arms;
- a spring extending axially between said gripping arms, one end of said spring engaging said gripping arms and an opposite end of said spring engaging said ball actuator, said ball actuator normally biased to a position between rearward ends of said gripping arms to thereby hold said gripping arms in the closed gripping position;
- a firing pin axially aligned and engageable with said ball actuator;
- and
- a handle for effecting movement of said firing pin and said spring biased ball actuator so as to cause said ball actuator to move forwardly, permitting said gripping arms to move from said closed gripping to said open releasing position.
