Abstract

A trigger acting upon a lever pivotally attached to a body urges the lever to overcome a magnetic force attracting the lever to a segment of the body and to pivot from a first position to a second position, which trigger is not positionally moved until the magnetic force is overcome. A jaw has a first position for retaining a bowstring and is maintained in the first position by the lever being in the first position. When the lever pivots to the second position, the jaw under influence of a force imposed by the bowstring pivots to a second position and releases the bowstring. A further pair of magnets may be used to create an opposing magnetic force to further urge maintenance of the lever in the first position.

Claims

1. A magnetic release for a bowstring, said release comprising in combination:

a) a body;

b) a jaw pivotally supported on said body, said jaw having a first position for capturing the bowstring and a second position for releasing the bowstring;

c) a lever pivotally supported on said body having a first position for retaining said jaw in the first position and having a second position for accommodating movement of said jaw to the second position;

d) a magnet for providing a magnetic force to magnetically retain said lever in the first position; and

e) a trigger acting upon said lever for urging said lever from its first position to its second position to permit release of the bowstring.

2. The magnetic release as set forth in claim 1 wherein said trigger is attached to said lever.

3. The magnetic release as set forth in claim 2 including a pin for pivotally supporting said lever and wherein said magnet is disposed adjacent said lever intermediate said pin and said jaw.

4. The magnetic release as set forth in claim 1 wherein said jaw includes an indentation and wherein an end of said lever is in contacting relationship with said indentation when said lever is in the first position.

5. The magnetic release as set forth in claim 4 wherein said lever is disengaged from said indentation when said lever is in the second position.

6. The magnetic release as set forth in claim 1 wherein said jaw includes a slot for receiving the bowstring.

7. The magnetic release as set forth in claim 6 wherein said body includes an anvil extending across said slot when said jaw is in the first position.

8. The magnetic release as set forth in claim 1 wherein said jaw includes a post and wherein said post bears against the end of said lever in response to a force exerted by the bowstring upon said jaw when said jaw is in the first position.

9. The magnetic release as set forth in claim 8 wherein said lever includes a rod for bearing against said post.

10. The magnetic release as set forth in claim 9 wherein said rod is of low friction material.

11. The magnetic release as set forth in claim 9 wherein said post is of low friction material.

12. The magnetic release as set forth in claim 11 wherein said rod is of low friction material.

13. The magnetic release as set forth in claim 1 including a second magnet supported by said lever for magnetically attracting said magnet.

14. The magnetic release as set forth in claim 1 including a second magnet supported by said lever for magnetically opposing said magnet.

15. The magnetic release as set forth in claim 14 including a third magnet supported by said body for magnetically attracting said lever.

16. The magnetic release as set forth in claim 15, said second magnet being positionally adjustable.

17. The magnetic release as set forth in claim 1 wherein said lever comprises a pair of pivotally mounted levers, one of said levers being in engagement with said trigger and the other of said levers being in engagement with said jaw.

18. The magnetic release as set forth in claim 17 including a first magnet mounted on said second lever and a second magnet mounted on said jaw for magnetically attracting said first magnet.

19. The magnetic release as set forth in claim 18 including a third magnet mounted upon said first lever for magnetically attracting said body.

20. The magnetic release as set forth in claim 1 wherein said lever comprises said trigger and wherein said lever comprises a section of a disc.

21. The magnetic release as set forth in claim 20 wherein said magnet is mounted on said section for magnetically attracting said jaw.

22. A magnetic release for a bowstring, said release comprising in combination:

a) a body;

b) means pivotally mounted on said body and having a first position for capturing the bowstring and a second position for releasing the bowstring;

c) means pivotally supported on said body having a first position for retaining said capturing means in the first position and having a second position for accommodating movement of said capturing means to the second position;

d) means for providing a magnetic force to draw said retaining and accommodating means to the first position; and

e) means for overcoming the magnetic force to accommodate repositioning of said retaining and accommodating means from the first position to the second position.

23. The magnetic release as set forth in claim 22 including further means for establishing an opposing magnetic force to resist movement of said retaining and accommodating means from the first position to the second position.

24. The magnetic release as set forth in claim 23 including means for adjusting the degree of opposing magnetic force by said further establishing means.

25. A method for magnetically releasing a bowstring from a hand held body, said method comprising the steps of:

a) capturing the bowstring with a jaw in a first position;

b) releasing the bowstring from the jaw in a second position;

c) retaining the jaw in the first position with a pivotable lever;

d) urging the lever into a first position with a magnetic force emanating from the body to exercise said step of retaining; and

e) providing a bias to the lever sufficient to overcome the magnetic force to reposition the lever into a second position to permit exercise said step of releasing.

26. The method as set forth in claim 25 wherein said biasing step is carried out by a trigger in operative engagement with said lever.

27. The method as set forth in claim 26 including the step of preventing movement of the trigger until the magnetic force is overcome.

28. The method as set forth in claim 25 including the step of providing a further magnetic force to resist movement of the lever from the first to the second position.

29. A triggerless magnetic release, said magnetic release comprising in combination:

a) a body, said body including means for gripping said body with a user'"'"'s fingers;

b) a pivotable jaw for capturing a bowstring when said jaw is in a first position and for releasing the bowstring when said jaw is in a second position;

c) an element for mechanically engaging said jaw in the first position of said jaw;

d) a magnet for producing a magnetic force to urge retention of said jaw in the first position and in mechanical engagement with said element;

e) a set screw for positionally adjusting the orientation of said element relative to said jaw and for locking said element in a selected position.

30. The triggerless magnetic release as set forth in claim 29 wherein said element is a section of a disc having an end and wherein said jaw includes an indentation for receiving said end.

31. The triggerless magnetic release as set forth in claim 30 wherein said jaw includes a hook for retaining the bowstring.
