Back-tension handheld archery release
A back-tension handheld archery release includes a handle and a sear assembly adjustably connected with the handle to lengthen and shorten a head release distance. The sear assembly includes a first sear and a click sear which is adjustable to control a click distance prior to firing a shot. In addition, the degree of rotation of the first and click sears relative to the head is adjustable to control the head speed of the sear assembly when the release is operated to release a bowstring and fire a shot.
1. An archery release, comprising
(a) a handle having a longitudinal axis and containing an opening;
(b) a sear assembly adjustably including a neck portion arranged within said handle opening for movement toward and away from said handle and operable between hold and fire positions upon pivotal movement of said handle to hold and release a bowstring, respectively; and
(c) a neck locking screw connected with said handle to lock said sear assembly neck portion relative to said handle.
2. An archery release as defined in claim 1 , and further comprising an adjustment screw connected with said neck portion and operable to move said neck portion relative to said handle.
3. An archery release as defined in claim 2 , wherein said sear assembly includes a head portion at an end of said neck portion spaced from said handle.
4. An archery release as defined in claim 3 , wherein said sear assembly further includes
(a) a first sear pivotally connected with said head portion; and
(b) a second sear pivotally connected with said head portion and coaxial with said first sear, said first and second sears being operable between hold and fire positions.
5. An archery release as defined in claim 4 , and further comprising a torsion spring arranged between said first and second sears to bias said first and second sears toward the hold position.
6. An archery release as defined in claim 5 , and further comprising a sear adjustment screw threadably connected with one end of said second sear and operable to adjust an overlap distance between said first and second sears, thereby to adjust the fire position of said sear assembly.
7. An archery release as defined in claim 6 , and further comprising a click sear locking screw connected with said second sear to lock said sear adjustment screw in a fixed position.
8. An archery release as defined in claim 6 , wherein said head portion contains a recess adjacent to a second end of said second sear and further comprising a spring arranged in said head portion recess to bias said second sear against said sear adjustment screw.
9. An archery release as defined in claim 6 , and further comprising a cage rotatably connected with said sear assembly head portion and a bail rotatably connected with said cage, said bail having one end configured to hold and release the bowstring and another end which engages said second sear, whereby said sear assembly is operable to hold and release said bail to hold and release the bowstring, respectively.
10. An archery release as defined in claim 5 , and further comprising a head adjustment screw connected with said head portion and engaging said second sear to limit the rotation of said second sear relative to said head portion, thereby to control the speed of said sear assembly.
11. A sear assembly for an archery release, comprising
(a) a head portion;
(b) a first sear pivotally connected with said head portion;
(c) a second sear pivotally connected with said head portion and coaxial with said first sear, said first and second sears being operable between hold and fire positions; and
(d) a torsion spring arranged between said first and second sears to bias said first and second sears toward the hold position.
12. A sear assembly as defined in claim 11 , and further comprising a sear adjustment screw threadably connected with one end of said second sear and operable to adjust an overlap distance between said first and second sears, thereby to adjust the fire position of said sear assembly.
13. A sear assembly as defined in claim 12 , and further comprising a click sear locking screw connected with said second sear to lock said sear adjustment screw in a fixed position.
14. A sear assembly as defined in claim 12 , wherein said head portion contains a recess adjacent to a second end of said second sear and further comprising a spring arranged in said head portion recess to bias said second sear against said sear adjustment screw.
15. A sear assembly as defined in claim 12 , and further comprising a cage rotatably connected with said head portion and a bail rotatably connected with said cage, said bail having one end configured to hold and release the bowstring and another end which engages said second sear, whereby said sear assembly is operable to hold and release said bail to hold and release the bowstring, respectively.
16. A sear assembly as defined in claim 11 , and further comprising a head adjustment screw connected with said head portion and engaging said second sear to limit the rotation of said second sear relative to said head portion, thereby to control the speed of said sear assembly.
