Abstract

An adjustable rope release for an archery bow, triggered by squeeze action of the fingers, which permits the archer to set the point in the squeeze motion at which the arrow is released. The rope release comprises a hand grip, for grasping by the index and middle fingers of the bowstring-drawing hand, from which a rope cord is looped around the bowstring and held by a hooked pin whose angle of projection relative to the grip member is adjustable by set screws. Squeezing of the middle finger of the hand causes the hand grip to pivot laterally relative to the drawn bow to a point which permits the rope loop to suddenly slip off the hooked pin, thereby releasing the bowstring and projecting the arrow toward its intended target.

Claims

1. A rope release for use with an archery bow comprising a grip adapted for grasping by the bowstring-drawing hand and configured with a pair of recesses for receiving portions of the forefinger and middle finger of the hand, a flexible cord loop whose terminal ends are attached to said grip, and a pin member projecting from said grip having a hook termination at one end adapted to releasably engage the bight portion of said loop and whose other end is attached to said grip between said recess pair, and adjustment means for permitting the angle of projection between said pin member and said grip to be varied to regulate the point at which said loop is freed from said hook termination during the squeezing of a user'"'"''"'"'s finger on the rope release.

2. The rope release of claim 1 wherein said adjustment means comprises a pivot dowel to which said pin member is attached and which is mounted for limited rotation within said grip, and fastener means for securing said pivot dowel at a present rotational position.

3. The rope release of claim 2 wherein indicia are associated with said pivot dowel for providing a visual indication of the rotational setting thereof.

4. The rope release of claim 1 wherein said loop is attached to said grip between said recess pair closely proximate said pin member.

5. The rope release of claim 1 further including fastener means for releasably securing said loop to said grip, thereby permitting replacement of said loops when needed.

6. A squeeze-action rope release for use with an archery bow comprising a hand grip of substantially E-shaped configuration having a pair of recesses for receiving portions of the forefinger and middle finger of the bowstring-drawing hand, a flexible cord loop whose terminal portions are attached to said grip between said recess pair therein, a pin member projecting from and coupled to said grip between said recess pair therein proximate said loop terminal portions, the projecting end of said pin member releasably engaging the bight portion of said loop after it has been bent around a bowstring, adjustment means for coupling said pin member to said grip to permit the angle of projection which said pin member makes with said grip to be varied to regulate the point at which said loop is freed from said pin member, whereby release of a bowstring is effected by squeezing of the middle finger of the hand while the forefinger remains substantially rigid, thereby rotating said grip relative to the drawn bowstring and causing said bight portion of said loop to slide off said pin member.

7. The rope release of claim 6 wherein said adjustment means comprises a pivot dowel to which said pin member is attached and which is mounted for limited rotation within said grip, and fastener means for securing said pivot dowel at a preset rotational position.
