Abstract

A bow string support lever is pivoted intermediate its ends on an arm which is in turn pivoted on a body member which includes a pair of finger grips. A catch on one end of the lever is arranged to engage a pawl operatively associated with the body member when the lever and arm are pivoted to a cocked position, whereby to secure the lever against pivotal movement. A hook on the opposite end of the lever is arranged to receive the bow string and to support the latter when in said cocked position. Upon slight lateral movement of the body member, the catch is disengaged from the pawl whereupon the lever is released to pivot from the cocked position and allow the bow string to disengage from the hook.

Claims

1. A triggerless archery bow string release, comprising:

a. an elongated body member having forward and rearward ends,

b. a finger grip connected to the rearward end of the body member and extending laterally from both sides of the body member,

c. an arm mounted pivotally at its rearward end on the body member on a transverse pivot mounting, projecting forwardly beyond the forward end of the body member, and extending generally along the longitudinal axis of the body member,

d. a bow string support lever mounted pivotally intermediate its ends of the forward end of the arm,

e. a catch on one end of the lever,

f. pawl means operatively associated with the body member for releasably engaging the catch for releasably securing the lever by rotating the body member in one direction about the pivotal axis of the arm to move the pawl means away from the catch to release the lever from cocked position and by rotating the body member in the opposite direction and rotating the lever so that the means will engage the catch, and

g. bow string retainer means on the opposite end of the lever for supporting a bow string when the lever is in said cocked position and for releasing a bow string when the lever is pivoted to uncocked position upon disengagement of the pawl means from the catch.

2. The bow string release of claim 1 including adjustment means on the body member operatively associated with the pawl means for varying the degree of sensitivity of release of the lever from its cocked position.

3. The bow string release of claim 2 wherein the pawl means comprises a fixed projection on the body member and the catch comprises a notch in the lever, and the adjustment means comprises a plurality of laterally spaced bearing means on the body member for selective engagement by the pivot mounting of the rearward end of the arm.

4. The bow string release of claim 2 wherein the pawl means comprises a pawl bar mounted on the arm for pivotal movement of its forward end toward and away from the catch, and a base member on the body member slidably supporting the rearward end of the pawl bar in the cocked position of the lever, the base member having a forward end over which the pawl bar is slidable to release the lever from its cocked position, and the adjustment means comprises means mounting the base member on the body member for adjustment of its forward end longitudinally relative to the pawl bar.

5. The bow string release of claim 1 wherein the pawl means comprises a fixed projection on the body member and the catch comprises a notch in the lever.

6. The bow string release of claim 1 wherein the pawl means comprises a pawl bar mounted on the arm for pivotal movement of its forward end toward and away from the catch, and a base member on the body member slidably supporting the rearward end of the pawl bar in the cocked position of the lever, the base member having a forward end over which the pawl bar is slidable to release the lever from its cocked position.

7. The bow string release of claim 6 wherein the base member comprises an adjustable bar mounted on the body member for adjustment of its forward end longitudinally relative to the pawl bar.

8. The bow string release of claim 1 wherein the finger grip is elongated laterally relative to the body member and is secured intermediate its ends to the body member, arm and lever for rotational adjustment relative to the body member.
