Abstract

A release device for pulling the midsection of a bow string, the device having a slot for receiving the bow string, and a pair of balls that engage one another to close the slot to retain the box string until such time as the user manipulates a trigger to permit separation of the balls and release the bow string.

Claims

1. pair of balls are engaged with a bow string..]. PG,5 2. A bow string release device comprising:

a body having a slot for receiving a bow string;

a pair of balls mounted in said body on opposite sides of the slot, said balls being relatively movable from a first position in which they are adjacent one another and engage the bow string to prevent removal thereof from said slot, toward a second position in which they permit passage of the bow string therebetween;

a release member mounted on the body so as to be movable between a string-retaining position in which it prevents movement of the balls from said first position, and a release position permitting movement of the balls toward said second position;

means connected to the release member for moving it from the string-retaining position to the release position at such times as said pair of balls are engaged with a bow string.Iadd.;

.Iaddend.and .[.;

.].

including a trigger member pivotally connected to the body and engaged with the release member in such a manner that as the trigger member is moved from a first trigger position toward a second trigger position, the release member is moved from the string-retaining position towards the release position.Iadd.; and

said release member being slidably mounted relative to said body for linear movement therealong;

said trigger member having a cam which applies a positive force to said release member when the trigger member is moved from said first trigger position to said second trigger position for causing the release member to move linearly along said body to the release position; and

spring means located within said body for simultaneously biasing said trigger member to said first trigger position and said release member to

2. its string-retaining position.Iaddend.. 3. A bow string release device comprising:

a body having a slot for receiving a bow string;

a pair of balls mounted in said body on opposite sides of the slot, said balls being relatively movable from a first position in which they are adjacent one another and engage the bow string to prevent removal thereof from said slot, toward a second position in which they permit passage of the bow string therebetween;

a release member mounted on the body so as to be movable between a string-retaining position in which it prevents movement of the balls from said first position, and a release position permitting movement .[.ov.]. .Iadd.of .Iaddend.the balls toward said second position;

means connected to the release member for moving it from the string-retaining position at such times as said pair of balls are engaged with a bow string; and

in which the release member comprises a sleeve slideably mounted on the body and having a pair of openings disposed in alignment on opposite sides of the slot in the body at such times as the release member is disposed in said string-retaining position, one of the slots in the sleeve member being larger than the other slot to accomodate the nock of an arrow.

3. Iadd.. A bow string release device as defined in claim 2, wherein said cam engagement with said release member cams the release member to move linearly along said body to said release position;

and

said bow string release device further comprising;

said body being elongated, the slot being disposed at one end of the body;

handle means connected to the opposite end of the body relative to said slot;

the pair of balls being disposed adjacent one another in the string-retaining position, but being movable in a lateral direction with respect to the direction of motion of the release member on the body;

the release member comprising a sleeve-like member, linearly, slideably movable along the body in either a first direction toward the slot, or in the opposite direction, toward the handle means; and

first structure carried by the sleeve-like member and movable therewith, the first structure having a pair of abutments spaced in said lateral direction a distance at least as great as the combined diameters of the pair of balls and located on opposite sides of the pair of balls to prevent separation of the pair of balls a distance sufficient to pass the bow string between them when the release member is in said string-retaining position. .Iaddend. .Iadd.5. A bow string release device as defined in claim 4, and in which said first structure is moved toward the handle means as the trigger member is being moved toward the second trigger position. .Iaddend. .Iadd.6. A bow string device as defined in claim 4, and in which said trigger member has a cam slot and said release member has a pin extending transversely through the cam slot, said cam slot and pin forming a cam connection for achieving the said cam engagement between the trigger member and the release member. .Iaddend.
