Abstract

An archery bow string release is provided which includes a string draw and release mechanism which is pivotally mounted to a handle member by a universal pivot such as a ball joint. The bow string draw and release device has only one pivoted arm that is biased into engagement with an immovably fixed jaw so as to retain a bow string therebetween. The fixed jaw has a straight jaw that permits a bow string to move when released in a forward direction without any interruptions. The biased jaw has a forward end portion that presents the only inpediment to a drawn bow string.

Claims

1. A bow string draw and release assembly comprising:

a. a handle member adapted to be gripped by the human hand;

b. catch and release means for releasably engaging a bow string means;

c. said catch and release means having a portion remote from said first end and a portion of said handle member cooperating to form a universal pivot, said universal pivot joining said handle and said catch and release means, and a portion of said catch and release means remote from said first end cooperating with said handle member and forming a connection therebetween, said connection comprising a means for permitting said handle member to pivot freely within a first plane substantially perpendicular to the line of draw of a bow string and to also permit said handle member to have limited pivotal movement in a second plane perpendicular to the first plane.

2. An assembly in accordance with claim 1 wherein said universal pivot is a ball joint.

3. An assembly in accordance with claim 2 wherein said handle member has an opening therethrough which forms the socket surface of the ball joint.

4. An assembly in accordance with claim 3 wherein the catch and release means includes a first jaw, a second jaw pivotally joined to said first jaw, the forward portions of said jaws when closed defining a region for engaging a bow string, detent means biasing said second jaw towards a closed position, and means for releasably locking said jaws in a closed position.

5. An assembly in accordance with claim 4 wherein a rear portion of said first jaw has a spherical section adapted to pivotally engage the socket surface of the handle member, thereby forming said ball joint.

6. An apparatus in accordance with claim 5 wherein said means for releasably locking said jaws is a pivoted lever arm and said second jaw has a relieved region adapted to cooperate with said arm to hold said jaws in a releasably open position.

7. Apparatus in accordance with claim 4 wherein a forward portion of said first jaw formiNg a string engaging surface of said first jaw has a straight side in the direction of motion of said bow string when released.

8. Apparatus in accordance with claim 7 wherein said second jaw has a bead on the forward portion thereof which defines with said first jaw the string engaging region.

9. Apparatus in accordance with claim 1 wherein a sight is mounted to the catch and release means.

10. A bow string catch and release assembly comprising a first jaw, a second jaw pivotally joined to said first jaw, said first jaw formed by a straight wall surface of said assembly, said first jaw being immovably fixed relative to said assembly, forward portions of said jaws when closed defining a region for engaging a bow string,, said second jaw having a lateral projection from the forward end of the jaw which engages a bow string, said second jaw being in mating engagement with the first jaw when a bow string is gripped, detent means for locking said jaws in a closed position until release is desired, said second jaw providing the sole impediment for a drawn bow string in the direction of bow string release, said second jaw being an elongated plate like member and being pivoted about a vertical axis from a locked position wherein said second jaw engages the side of the locking means to an inlatched position wherein the second jaw underlies the locking means, spring means biasing said jaws in a closed position, said locking means being pivoted about a horizontal axis, and means for releasing said detent means to permit said jaws to open thereby releasing a bow string.
