Abstract

An archery release device and method are disclosed herein. The archery release device, in an embodiment, includes a trigger, a leverage link and a cord holder. In the hold arrangement, the trigger, the leverage link and the cord holder are coupled together through a direct connection or an indirect connection. The coupling, direct or indirect, causes the cord holder to hold a draw cord when the cord holder is subject to a pulling force. In the release arrangement, a release interface of the leverage link is decoupled from the trigger, and another release interface of the leverage link is decoupled from the cord holder.

Claims

1. An archery release device comprising:

a support;

a trigger moveably coupled to the support;

a leverage link pivotally coupled to the support, wherein the leverage link is configured to pivot about a fulcrum point, wherein the leverage link comprises first and second arms, wherein;

the first arm extends from the fulcrum point;

the first arm extends at least partially along a first arm axis;

the first arm comprises a first release interface located a lever distance from the fulcrum point;

the second arm extends in a direction opposite of the first arm;

the second arm extends at least partially along a second arm axis;

the second arm comprises a second release interface positioned on the second arm axis; and

the second arm axis is offset from the first arm axis by an offset distance;

a cord holder pivotally coupled to the support, wherein the cord holder comprises;

a cord engager configured to hold an archery draw cord that is applying a pulling force to the cord engager; and

a third release interface,

wherein the leverage link and the cord holder are configured to cooperate with each other, in response to a movement of the trigger, to establish one of a hold arrangement and a release arrangement,

wherein, in the hold arrangement, the trigger, the leverage link and the cord holder are coupled together through one of a direct connection and an indirect connection to cause the cord holder to hold the archery draw cord when the cord holder is subject to the pulling force,

wherein, in the release arrangement, the first release interface is decoupled from the trigger, and the second release interface is decoupled from the third release interface of the cord holder to cause the cord holder to release the archery draw cord when the cord holder is subject to the pulling force,

wherein the hold arrangement is configured to transition to the release arrangement in response to a trigger force that is applied to the trigger,

wherein the lever distance is greater than the offset distance to reduce a magnitude of the trigger force that is necessary to cause the transition.

2. The archery release device of claim 1, wherein the support comprises a body that defines a cavity, wherein the leverage link is positioned within the cavity.

3. The archery release device of claim 2, wherein a portion of the trigger is positioned within the cavity.

4. The archery release device of claim 1, comprising a trigger link pivotally coupled to the support, wherein the trigger link comprises a trigger release interface configured to be coupled to the first release interface.

5. The archery release device of claim 4, wherein, in the hold arrangement, the first release interface is engaged with the trigger release interface.

6. The archery release device of claim 4, wherein, in the release arrangement, the first release interface is disengaged from the trigger release interface.

7. The archery release device of claim 6, wherein the first release interface comprises a first travel length, and the trigger release interface comprises a second travel length, wherein the first and second travel lengths differ by less than fifty percent (50%).

8. The archery release device of claim 6, wherein the first release interface comprises a first travel length, and the trigger release interface comprises a second travel length, wherein the first and second travel lengths differ by less than twenty five percent (25%).

9. The archery release device of claim 4, comprising a trigger link adjuster that is at least partially positioned within a cavity defined by the support, wherein the trigger link adjuster is configured to contact the trigger link.

10. An archery release device comprising:

a support;

a trigger moveably coupled to the support;

a leverage link pivotally coupled to the support, wherein;

the leverage link is configured to pivot about a fulcrum point,

the leverage link comprises first and second arms, each of which extends along an axis,

the first arm comprises a first release interface located a lever distance from the fulcrum point;

the second arm comprises a second release interface; and

the axes are offset by an offset distance; and

a cord holder pivotally coupled to the support;

wherein the leverage link and the cord holder are configured to cooperate with each other, in response to a movement of the trigger, to establish one of a hold arrangement and a release arrangement,

wherein, in the hold arrangement, the trigger, the leverage link and the cord holder are coupled together through one of a direct connection and an indirect connection to cause the cord holder to hold a draw cord when the cord holder is subject to a pulling force,

wherein, in the release arrangement, the first release interface is decoupled from the trigger, and the second release interface is decoupled from the cord holder.

11. The archery release device of claim 10, wherein the support comprises a body that defines a cavity, wherein the leverage link is positioned within the cavity.

12. The archery release device of claim 10, wherein the first and second arms extend in opposite directions.

13. The archery release device of claim 10, comprising a trigger link pivotally coupled to the support, wherein the trigger link comprises a trigger release interface configured to be coupled to the first release interface.

14. The archery release device of claim 13, wherein, in the hold arrangement, the first release interface is engaged with the trigger release interface.

15. The archery release device of claim 14, wherein, in the release arrangement, the first release interface is disengaged from the trigger release interface.

16. The archery release device of claim 15, wherein the first release interface comprises a first travel length, and the trigger release interface comprises a second travel length, wherein the first and second travel lengths differ by less than twenty five percent (25%).

17. The archery release device of claim 13, comprising a trigger link adjuster that is at least partially positioned within a cavity defined by the support, wherein the trigger link adjuster is configured to contact the trigger link.

18. A method for manufacturing an archery release device, the method comprising:

obtaining a support;

coupling a trigger to the support so that the trigger is moveable relative to the support;

structuring a leverage link to comprise first and second arms, each of which extends along an axis, wherein;

the first arm comprises a first release interface located a lever distance from a fulcrum point;

the second arm comprises a second release interface; and

the axes are offset by an offset distance; and

coupling the leverage link to the support so that the leverage link is pivotal relative to the support so that the pivoting occurs about the fulcrum point;

coupling a cord holder to the support so that the cord holder is pivotal relative to the support; and

arranging the leverage link and the cord holder to cooperate with each other, in response to a movement of the trigger, to establish one of a hold arrangement and a release arrangement,

wherein, in the hold arrangement, the trigger, the leverage link and the cord holder are coupled together through one of a direct connection and an indirect connection to cause the cord holder to hold a draw cord when the cord holder is subject to a pulling force,

wherein, in the release arrangement, the first release interface is decoupled from the trigger, and the second release interface is decoupled from the cord holder.

19. The method of claim 18, comprising configuring the support to define a cavity, wherein the leverage link is positioned within the cavity.

20. The method of claim 18, comprising:

configuring a trigger link to comprise a trigger release interface configured to be coupled to the first release interface; and

coupling the trigger link to the support so that the trigger link is pivotal relative to the support,

wherein, in the hold arrangement, the first release interface is engaged with the trigger release interface,

wherein, in the release arrangement, the first release interface is disengaged from the trigger release interface.
